Carbohydrates Carbohydrates are found in foods such as:fruits,vegetables, foods made with sugar, grains, and different types of bread. There are two types of carbohydrates, simple carbohydrates and complex carbohydrates. Normally complex carbohydrates are the healthiest ones in food. Yeast is a good example of carbohydrates, as in one of my resources it states Yeast was found in sugars, aspirin, essential oils, hydrogen peroxide, and acetic acids. Due to a new study and experiment too much of these things can cause cell death. So not all carbohydrates are useful in life, though these things help if use them too much it will result in cell death and I don’t think you want that. Apoptosis is found in carbohydrates and as shown in many studies …show more content…
There are 2 types of nucleic acids:DNA and RNA. This is found in the nucleus of the cell and passes through genetics. Nucleic Acids contain phosphorus and nitrogen. The food that contain Nucleic Acids are:Livers/Organ meats, seafood, dairy products, and any types of nuts. Only nuts and dairy products are not very high in nucleic acids. In other words the function of nucleic acids are for storing genetic information that every person needs to function. Scientist say that the building blocks to nucleotides are polynucleotides which are really long chains of nucleotides. The 3 parts to a nucleic acid is 5 carbon sugars, a phosphate group, and a nitrogen base. Some interesting facts about Nucleic acids: Nucleic acids code your genes, they are used in protein synthesis, repair, and reproduction. A nucleotide is a double helix made of two strands of polymers. If we did not have nucleotides we would get information to our cells and we wouldn’t be able to code our genes. Another interesting fact is scientist 1st found Nucleic acids in the cell's nucleus. DNA gives kinda a blueprint off of how an organism is made in other words a genetic code. DNA and RNA are made up of Nucleic Acids, the base that make up the DNA and RNA is nucleic acids so it is important to ingest them so your cells can keep copying your
DNA is made up of nucleotides, and a strand of DNA is known as a polynucleotide. A nucleotide is made up of three parts: A phosphate (phosphoric acid), a sugar (Deoxyribose in the case of DNA), and an organic nitrogenous base2 of which there are four. The four bases are as followed: Adenine (A), Cytosine
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)
Since DNA has the instructions for making the proteins, but it has to be highly protected, it doesn’t leave the nucleus where it is mostly found (Hall, 6). DNA’s function is to be a long-term storage and transmission of the genetic information (DNA vs RNA, 2014). Copies of certain instructions needed for proteins can be made in the form of RNA. It’s not an exact copy of what is found in DNA, but RNA can travel out of the nucleus with the instructions. RNA make...
The Structure and Function of Carbohydrates Large biological molecules are called macromolecules, there are giant molecules (polymers) made up of repeating units (monomers). Carbohydrates are one of the main classes of biological molecules. Macromolecule units (monomers) are joined together by condensation reactions and hydrolysis reactions split macromolecules down into their individual units. Carbohydrates are molecules that contain elements of carbon, hydrogen, and oxygen. Carbohydrates have a 2:1 hydrogen to oxygen ratio, there are twice as many hydrogen atoms as oxygen atoms (the same proportion as in water).
Carbohydrates are split into two main groups. The simple sugars and the starches. Simple sugars contain fructose, glucose and lactose. All three sugars can be found in most fruits. The starches are found in bread, rice, some fruits, some vegetables, and potatoes. Carbohydrates are mainly tasked with providing your body energy. However, in some instances where the body lacks enough fibre, the carbohydrates can be broken down to provide a replacement for fibre.
Chemistry dictates the structure of DNA. DNA is a polymer of monomers called nucleic acids. These are made of a nitrogenous base, a phosphate group and a sugar. It is the negative charge on the phosphate group that makes DNA an acid. There are 4 different bases: adenine, thymine, guanine and cytosine. In groups of three, these four bases can code for any protein coded for in an organism’s genome. Two strands of nucleic acids stack on top of each other in a double helix. The backbone of the nucleic acids consists of the interaction between phosphate groups and the hydroxide groups of nucleic acids. These are held together by covalent bonds called phosphodiester bonds. The helix itself is held together by hydrogen bonds. Although h...
Generally the most feared and hated macro nutrient is the carbohydrate. It is technically not the most fattening nutrient, (Carbohydrates provide 4 calories per gram whereas actual fat provides 9.) yet carbohydrates are much more numerous in the foods that contain them. For instance, white bread or ice cream contain multitudes of carbohydrates since they are simple sugars, but don't contain nearly the same amounts of fat. Carbohydrates at the basic level are made from carbon, hydrogen, and oxygen. It is these three elements that make up the sim...
The primary method to control gestational diabetes mellitus (GDM) is through dietary regulation. The most effective method to control GDM via diet is through carbohydrate restriction and/or selectivity. It is recommended that pregnant women with GDM reduce their carbohydrate intake to 40% of the total caloric intake or can maintain a 60% carbohydrate intake but those carbohydrates must all come from low glycemic index foods. Examples of low glycemic foods are apples, spinach, black beans, split peas, oatmeal, and quinoa. Additional suggestions are to eat complex carbohydrates instead of simple, refined sugars. Eat small, frequent meals and snack often in between meals in order to maintain constant glucose levels throughout the day.
Although the diet may cause one to lose weight, critics have found the diet to have considerable drawbacks. The Atkins diet restriction on carbohydrates is not very healthy since complex carbohydrates such as fruits, vegetables, and whole grains are found to contain essential nutrients and rich in fiber. Fiber is known to slow the absorption of food, which prevents blood glucose to rise and reduce insulin surges, therefore decreasing desire to eat. Critics have found that simple carbohydrates should be substituted for complex carbohydrates instead of eliminating carbohydrates from the diet completely. Complex carbohydrates and whole foods are rich in photochemical, bioflavonoid, carotenoids, and other substances that may reduce the risk of many chronic diseases.
1. DNA is a nucleic acid that carries the genetic information in the cell and is capable of self-replication and synthesis of RNA. DNA consists of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. The sequence of nucleotides determines individual hereditary characteristics.
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.
Severely restricting carbohydrates is not healthy and offers little advantages in terms of fat loss. Consumers of low carbohydrate products are often deceived into believing all low carbohydrate products are better for their health. However, usually when a product claims to have a low amount of carbohydrates, it fails to mention the increase of fats and proteins the product gains to compensate for the lost carbohydrates. In reality low carbohydrate diets increase health risks and give dieters false hopes. Carbohydrates are significant in supplying energy to the body’s needs. Through plenty of carbohydrates, especially for active people and athletes, the body is able to use its’ adequate amounts of energy efficiently.
The reality behind the common practice of taking vitamin supplements is less dramatic, although vitamins do represent an important component of the necessary human diet. The word vitamin was formed from the Latin word for life, "vita," and the Greek word "amine", because 19th century scientists believed that they were formed only from amino acids. Amino acids are the twenty essential code elements which arrange themselves in varied sequences or chains to form complex proteins, the basic foodstuff of life. These organic acids (containing the essential ingredient NH2), in conjunction with the nucleic acids (DNA material being composed of the four bases adenine, guanine thymine and cytosine), "translate" the genetic instructions from the DNA of the chromosome to the RNA transcript, and in turn transfer these instructions from the transcript to proteins.
Carbohydrates supply the body with the energy it needs to function. They are found almost exclusively in plant foods, such as fruits, vegetables, peas, and beans. Milk and milk products are the only foods derived from animals that contain a significant amount of carbohydrates.
“If we could give every individual the right amount of nourishment and exercise not too little not too much, we would have food the safest way of health” (Barasi.E.M, 2003). This essay is going to discuss on the important of six essential nutrients in human body. According to PosnerB.M (1998), he define essential nutrients as a nutrients that the body cannot synthesize on its own-or not to an adequate amount and must be provided by the died. Oxford dictionary (2009), also define essential nutrients as are those nutrients that are required by the body and cannot be synthesise in the adequate amount to meet requirement, so must be provided by the diet. Essential nutrients are those found to be essential to human life and optimal function, Williams.M. H (2006).There are six main type of nutrients used to maintain body health. They are carbohydrates, protein, fat, vitamins, minerals and water. They must be in balance for the body to function properly.
