Biochemistry
What is Biochemistry? Biochemistry is everything from the elements to dehydration synthesis. What is an element? An element in a pure substance that can be broken down in to smaller units called protons neutrons and electrons. There are over 100 elements on our planet. Did you know that DNA is a nucleotide because of it basic structural units which contains sugars joined together to form what looks like a winding ladder?
Elements can be bonded either by covalent bond, ionic bond, peptide bond or hydrogen bond.. Each bond is a chemical attraction between electrons. Once an chemical has bonded and it is written on paper the written bond is knew as a chemical formula. Another written bond is called a structural formula which is an expanded molecular formula showing the same thing as a chemical formula. In order for there to be a brand new chemical formed there must be some from of oxidation which is the transfer of electrons or reduction which is the subtraction of electrons. Sometime a element forms an organic compound which is a compound that includes Carbon. There are many more compounds such as monomer which is a chemical compound that can undergo polymerization or polymer which can be either a mixture or a compound formed but polymerization and consisting essentially of repeating structural units such as a glucose molecule. Also an isotope is any of two or more species of atoms with the same atomic number and a similar chemical behavior but with a different atomic mass
Biochemistry isn’t just about the elements it’s also about foods. There are many saturated and unsaturated fats in foods. Many most people don’t know about them. Amino acids are acids synthesized by living cells or obtained as essential components of a diet. In other words they are the fats in food. Much like a phospholipid which are numerous lipids in which phosphoric acid as well as fatty acids. A lot of food carry glucose which is the chemical word for sugar. Starch is a white odorless and tasteless powdery complex carbohydrate. Another type of carbohydrate is glycogen which is a white amorphous tasteless polysaccharide that is the principal form in which carbohydrates are stored. Steroid is any of numerous compounds containing a 17 carbon 4 ring system the includes various hormones. In order to make all these acids used in food useable the must be denature which means to deprive of natural qualities.
To uncover organic compounds like carbohydrates, lipids, proteins and nucleic acid, by using tests like Benedict, Lugol, Biuret and Beta Carotene. Each test was used to determine the presents of different organic molecules in substances. The substances that were tested for in each unknown sample were sugars, starches, fats, and oils. Moreover, carbohydrates are divided into two categories, simple and complex sugars. Additionally, for nonreducing sugars, according to Stanley R. Benedict, the bond is broken only by high heat to make make the molecules have a free aldehydes (Benedict). As for Lipids, there are two categories saturated and unsaturated fats. One of the difference is that saturated fats are mostly solids and have no double bond (Campbell Biology 73). The Beta Carotene test works by dissolving in a lipid, thus giving it color to make it visible. Moreover, proteins are made out of amino acids that are linked by a polypeptide bond (Campbell Biology 75). The purpose of this experiment was to determine whether an unknown class sample or food sample had any carbohydrates, lipids, or proteins in it. The expected result of the lab was that some substances would be present while other would be absent.
Carbohydrates are biomolecules that consist of a chain or ring of carbon atoms attached to hydrogen and oxygen atoms. The simplest formula for carbohydrates is (CH2O)n. Carbohydrates are important to organisms for a variety of reasons. They are used to form the structural components of the cell, aid in energy storage, and serve as intermediary compounds for more complex molecules. Carbohydrates are classified as either monosaccharides, disaccharides, or polysaccharides. Both monosaccharides and disaccharides dissolve easily in water. Carbohydrates are produced in plants through the process of photosynthesis and animals obtain these carbohydrates by eating the plants. ("BIO 1510 Laboratory Manual," 2016)
Proteins are one of the main building blocks of the body. They are required for the structure, function, and regulation of the body’s tissues and organs. Even smaller units create proteins; these are called amino acids. There are twenty different types of amino acids, and all twenty are configured in many different chains and sequences, producing differing protein structures and functions. An enzyme is a specialized protein that participates in chemical reactions where they serve as catalysts to speed up said reactions, or reduce the energy of activation, noted as Ea (Mader & Windelspecht).
Covalent compounds are formed when two or more non-metals react together. The covalent compound is actually made of molecules, and the name given depends on the structure of these molecules. Prefixes, like di- for two, tri- for three, tetra- for four, and so forth, are frequently used. Thus, NO2 is nitrogen dioxide and N2O4 is dinitrogen
Polydactyly is the most commonly observed congenital digital anomaly of the hands and feet appearing in 1 in every 500 live births. The condition is characterized by an abnormal amount of digits per hand in which the extra digits may develop bilaterally, or it may occur on both or just one hand, foot, or some other combination. Usually the extra digits that develop are either small pieces of soft tissue or fully formed in appearance. It is noted that in around 80% to 90% of cases involve the peripheral digits, although it is possible that all digits may be affected. Depending on the location of the extra digit, polydactyly can be further classified into three types: pre-, post-, and central axial forms. Polydactyly can occur as an isolated disorder (non-syndromic) or alongside other symptoms or disease. Isolated polydactyly is typically caused by the inheritance of an autosomal dominant gene mutation, meaning the cause is not due to a multifactorial trait. However, most cases of polydactylism are linked to specific syndromes that cause congenital anomalies through a variety of gene mutations.
Carbohydrates, fats, and protein are the three nutrients in food. Carbohydrates consist of foods like starches, vegetables, fruits, dairy products, and sugars. Fats are foods such as butter, margarine, salad dressing, oil, nuts, meat, poultry, fish and some dairy products. Foods that provide protein include meat, poultry, fish, cheese, milk, dairy products, eggs, and dried beans.
Proteins are any of a large class of complex organic chemical compounds that form the basis tissues and play a central role in biological processes (The American Heritage Student Science Dictionary 272). Proteins are essential to building muscle mass.
Also, I will know what a chemical and physical property is and I will know how to find them out. Materials = == == ==
Isotopes: Atoms of the same element (same atomic number) but with differing numbers of neutrons, different mass numbers.
Nutrients are the chemicals that humans need to live and grow. Humans obtain their nutrients from the food and water that they drink. They are used to build and repair tissues and regulate body processes and are converted to and used as energy. Lipids are a category of nutrients. Lipids consist of fats, oils, and waxes and are very important for are body’s health. Lipids are important for the human body because they are for storing energy, they’re good at storing energy because they can concentrate a group of calories in a smaller area.
.... Without these systems humans would be extinct, because these systems provide humans the nutrients, energy, oxygen, and many other substances that humans cannot live without. All these systems and functions work together as a whole. Biochemistry helps develop medicine and medicine is used every day in life. Without medicine many diseases and flus would not be cured. But not everyone catches or has the same types of diseases or flus, therefore biochemists developed different medication for different bodies and flus. But it is in the hands of the doctors, pharmacists, or the physician’s to prescribe the right medication for the patient, and this is taught in biochemistry. Therefore a student who wants join to the medical field should study human anatomy so the he/she is aware of the human structure. And also study biochemistry to have strong knowledge in medicine.
The most important nutrient categories are starches, minerals, sugars, and electrolytes. Starches and minerals fit into the area of complex carbohydrates. Complex carbohydrates are polysaccharides (many sugars bonded together). Because of the multiple bonds, polysaccharides are able to store energy for later use. Simple sugars make up the other group of carbohydrates. The bonding structures of simple sugars are much less advanced that than those of complex carbohydrates. This allows for the burning of simple sugars in an athlete's body. Electrolytes are a category of their own because they are helpful to an athlete all of the time, whether energy storage or energy burning is needed.
Chemical reactions involve the making and breaking of bonds. It is essential that we know what bonds are before we can understand any chemical reaction. To understand bonds, we will first describe several of their properties. The bond strength tells us how hard it is to break a bond. Bond lengths give us valuable structural information about the positions of the atomic nuclei. Bond dipoles inform us about the electron distribution around the two bonded atoms. From bond dipoles we may derive electronegativity data useful for predicting the bond dipoles of bonds that may have never been made before.
“Nutrients are the nutritious components in foods that an organism utilizes to survive and grow. Macronutrients provide the bulk energy for an organism's metabolic system to function, while micronutrients provide the necessary cofactors for metabolism to be carried out” (Nutrient. (2014, March 24). Nutrients are divided into many parts such as carbohydrates, proteins, lipids, vitamins, minerals, water, and fiber. Each of them have their own roles in a human body. “The role of carbohydrates is to provide energy, as they are the body’s main source of fuel, needed for physical activity, brain function and operation of the organs” (Healthy Eating. (n.d.). “Protein is a major part of the skin, muscles, organs, and glands. Protein is also found in all body fluids, except bile and urine.” (Protein in diet: MedlinePlus Medical Encyclopedia. (n.d.). “Lipid stores in your body function as an energy reserve to fuel your essential body functions, such your heart beating and breathing, when you go a long period of time without eating. Lipids also play a role in the formation of your cell...
All of these substances serve one purpose or another when consumed into the body. Carbohydrates, for example, are broken down in the body to provide energy for the body to perform reactions and to regain stamina. Protein helps muscles to recover stronger than before as well as help skin and hair cells to develop. Some substances, such as fat and sugar, can be misinterpreted as being harmful to the body. However, fats and sugars are vital to the human body and without them certain processes within the body could not take place ("What's In Food", Nutriti...
