Biology, The Five Major Compounds :: essays research papers

Compounds That Compose the Human BodyThere be five major groups of compounds that compose the military personnel body. They argon carbohydrates, lipids, proteins, nucleotides, and water. These are totally very primary(prenominal) to humans and without them we would not be able to survive. They live with 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 121. 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 or so numerous molecules in living organisms. They play a major part as food molecules in the cell, being broken down to get out energy. Polysaccharides play an important role serving as energy reserves also. It provides a quick-release energy source that keeps us going between meals. wee am ounts of carbohydrates are also used for structural purposes and others are attached to outside surfaces of cell membranes to guide cellular interactions. For many cells, sugars are the about important source of energy. Lipids are important because they function as structural percentages of cell membranes, sources of insulation, and a mean of energy entrepot. The lipid molecules are most thoroughly known as forming basic structures of cell membranes and as energy storage molecules as well. In this group of lipids, there are about trio main types authoritative fats (triglycerides), phospholipids, and steroids. True fats represent the bodys most abundant and concentrated source of usable energy. When they are oxidized, they yield considerable amounts of energy. They are stored chiefly in fat deposits beneath the skin and close to body organs, where they help insulate the body and protect deeper body tissues from agitate loss and bumps. True fats are a storage form for overp lus food, they are stored energy. Any type of food consumed in excess pick up 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 proneness 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.
