Document Summary
Proteins compounds composed of carbon, hydrogen, oxygen, and nitrogen atoms; arranged into amino acids linked in a chain. Amino acids building blocks of proteins; amino means containing nitrogen. All amino acids have the same basic structure: A central carbon (c) atom with a hydrogen (h) atom attatched. This distinguishes the amino acids from one another. The side groups in amino acids vary from one to the next; this makes proteins more complex than both carbohydrates and fats. There are 20 di erent amino acids in total. While amino acids all share a common structure, they di er in size, shape, electrical charge, etc. More than half of the amnio acids are nonessential amino acids amino acids that the body can make or synthesize on its own. There are 9 essential amino acids amnio acids that the body requires but cannot make, therefore they must be supplied by the diet. These are also referred to as indispensable amino acids.
