Biology, The Five Major Compounds :: essays research papers

Compounds That Compose the Human BodyThere atomic number 18 five major radicals of compounds that compose the human body. They are carbohydrates, lipids, proteins, nucleotides, and water. These are all very cardinal to humans and without them we would non be able to survive. They have many cash in ones chipss that advertise a human mobile phone and a human body to function.Carbohydrates admit 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 animation. 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 of the essence(p) role serving as energy reserves to a fault. 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 take up 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 sozzled 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 veritable fats (triglycerides), phospholipids, and steroids. trustworthy fats represent the bodys most abundant and intemperate source of usable energy. When they are oxidized, they yield large amounts of energy. They are stored in general in fat deposits beneath the skin and around body organs, where they financial aid 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. whatever 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 moving picture to sunlight. All of the sex hormones like estrogen and testosterone are also steroids.
