Amino acids are joined to create proteins. The carbon atom in each amino acid is joined to four different groups: COOH, NH2, H, and a variable group denoted by the symbol R.
This R might be an H, CH3, CH2SH, or another kind. A water molecule is eliminated from the formula when two amino acids are joined together. Numerous hundred amino acids can be used to create one protein. The protein's formula is extremely intricate as a result of everything mentioned above. Because they contain nitrogen, carbon, hydrogen, and oxygen, proteins differ from fats and carbohydrates. Fats contain fatty acids, which have a carboxyl group and an alkyl group and so only have carbon, oxygen, and hydrogen, whereas carbohydrates only have carbon, hydrogen, and oxygen.
