Compounds That Compose the Human Body
There are five major groups of compounds that compose the human body. They are carbohydrates, lipids, proteins, nucleotides, and water. These are all very important to humans and without them we would not be able to survive. They have many functions that encourage a human cell and a human body to function.
Carbohydrates include sugars and starches, contain carbon, hydrogen, and oxygen which appears in a ratio of 1:2:1. Carbohydrates are classified according to size as monosaccharides, disaccharides, and polysaccharides. The primary function of carbohydrates is to serve as sources of energy. Carbohydrates are some of the most numerous molecules in living organisms. They play a major role as food molecules in the cell, being broken down to produce energy. Polysaccharides play an important role serving as energy reserves also. It provides a quick-release energy source that keeps us going between meals. Small amounts of carbohydrates are also used for structural purposes and others are attached to outer surfaces of cell membranes to guide cellular interactions. For many cells, sugars are the most important source of energy.
Lipids are important because they function as structural components of cell membranes, sources of insulation, and a mean of energy storage. The lipid molecules are most well known as forming basic structures of cell membranes and as energy storage molecules as well. In this group of lipids, there are about three main types: true fats (triglycerides), phospholipids, and steroids. True fats represent the body’s most abundant and concentrated source of usable energy. When they are oxidized, they yield large amounts of energy. They are stored chiefly in fat deposits beneath the skin and around body organs, where they help insulate the body and protect deeper body tissues from heat loss and bumps. True fats are a storage form for excess food, they are stored energy. Any type of food consumed in excess need to be converted to fat and stored. Phospholipids although similar in structure to the true fats, are not stored energy but rather structural components of cells. Lecithin is a phospholipid that is part of our cell membranes and myelin provides electrical insulation for nerve impulse transmission. The third group is steroids and cholesterol is an important steroid. Cholesterol is another component of cell membranes and a form of cholesterol in the skin is changed to vitamin D on exposure to sunlight. All of the sex hormones like estrogen and testosterone are also steroids.
Carbohydrates pose a big role in food and diets as we are all very familiar with them. This macromolecule provides a short period of energy for our bodies through glucose, this is similar to how lipids store energy as well. Carbohydrates are found in eukaryotic cells on the outer surface of the cell membrane. A carbohydrate is made up of 3 different elements, carbon, hydrogen, and oxygen which is the same for the other 3
One of the four molecules is carbohydrates. Carbohydrates are made out of CHO. The main building blocks are sugars (saccharides). What carbohydrates do for us is they store fuel for our cells. They are fast energy. Glucose, fructose, and galactose are examples of single or simple sugar molecules or monosaccharide. Maltose, sucrose, and lactose are examples of two sugar molecules linked, also known as disaccharide. Starch, glycogen, and cellulose are examples of many sugar molecules linked. They are also called polysaccharide. If you wanted to test if there were carbohydrates in something you could do the sugar or the starch test.
Carbohydrates are more than just fuels for the body and have other uses. Carbohydrates are hydrocarbons containing a carbonyl group and many alcohol groups. Their polymers can complex or they be simple and contain just one repeating monosaccharide, the roles of polymers can be many such as structural, storage or even signalling. (Tymoczko et al, 2012 p. 131)
This includes glucose, which is produced by photosynthesis. Fructose, which is the sugar found in fruits, and galactose which is a simple milk sugar. Another example of Carbohydrates is Disaccharides, this includes maltose, sucrose, and lactose. Maltose, is grain sugar. People who have celiac disease are allergic to this because it is from the grain, and the substance does not react with the body in the right way. Sucrose is table sugar, which is used on the ordinary basis or in restaurants. Lastly for Disaccharides is Lactose, different from Galactose, which is a simple milk sugar. Lactose is more complex, giving the people allergic to milk products the name, Lactose intolerant. The last example is Polysaccharides. This includes starch, glycogen, and cellulose. Starch is most commonly known from potatoes, and can be of great use in gluten free cooking. As for glycogen , it’s found to be of many glucose linked together and cellulose is simply a plant
What are carbohydrates? What role do they play in our bodies? The role of carbohydrates in our bodies is to provide energy, as they are the body’s main source of fuel. These biochemicals are needed for physical activity, brain function and to operate the organs. Carbohydrates can be found in dairy, fruits, grains, and in starchy vegetables. Complex carbohydrates are foods which contain vitamins, minerals, and antioxidants. Oat meal, brown rice, quinoa, potatoes, beans, peas, whole grains and other starchy vegetables are good examples of complex carbohydrates. Simple carbohydrates are a major source of energy for the body and can be found in fruits, fruit juices, and dairy products. While both kinds of carbohydrates use glucose as a source,
Carbon is essential to many basic biological functions. Carbon’s unique properties are what make this element the basis of all living matter. Carbon is also responsible for the creation of monomers, polymers, and macromolecules. Monomers are small, simple units of carbon that have been strung together to form larger polymers. Polymers are more complex molecules made from individual carbon monomers. Macromolecules are very large molecules made from carbon based chains, such as polymers. The four classes of macromolecules include carbohydrates, proteins, lipids, and nucleic acids. The creation of these very important macromolecules is caused by the properties of carbon. These properties include carbon’s ability to form four covalent bonds, carbon’s
Lipids store energy in fat and act as structural components of cell membranes. They are an essential nutrient in the human body. Triglycerides (fats and oils) give the body the energy it needs to operate. They serve as components of hormones and vitamins.
Carbohydrates are divided into two groups based on how complex their structure is.Monosaccharides is a simple carbohydrate because it has one simple sugar, disaccharides has a combination of two simple sugars.An example of disaccharides is lactose.Complex carbohydrates also known as polysaccharides are known to have multiple sugars.Polysaccharides are also used to store energy, an example of this starch.In addition, nutrients include proteins ,fats, minerals and vitamins.Multiple tests were taken like Benedict’s Solution, Lugol’s Solution, and Biuret’s Solution to test if the presence of a substance was there.
Fats. This is essential for your body, as it helps maintain a healthy body. There are many different forms of fat. Some good and some bad. The ones that are good and form part of the macronutrient are fats such as saturated, monosaturated and omega 3,6,9. Fat is used as a means of protection for the body. It is used as insulation to keep a regular body temperature. Fat is also protects the organs of the body.
Polysaccharides are carbohydrates, their main function is to give us energy. They are polymers of monosaccharides made up of carbon, hydrogen, and oxygen. Starch is one form of a polysaccharide, it consists entirely of α- glucose molecules linked in long chains. Plants store glucose in the polysaccharide
Answer: Carbohydrates are sugars, carbohydrates are made up of a long chain of carbon atoms. Carbohydrates provide living things with energy.
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)
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.
Carbohydrates are the main source of glucose, which is a major fuel for all of the body's cells and the only source of energy for the brain and red cells. Except for fiber, which cannot be digested, both simple and complex carbohydrates are converted into glucose. The glucose is then either used directly to provide energy for the body, or stored in the liver for future use. When a person consumes more calories than the body is using, a portion of the carbohydrates consumed may also be stored in the body as fat.
There are many more lipids than I have mentioned in my research paper, there are over a 100 know lipids. Lipids are very important for our body and cells and they carry out many function. They provide nutrients for our body. 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. Lipids are also used to make soaps, detergents and waxes. These are things that we use in every day life.
