Proteins are unbranched polymers constructed from 20 standard α-amino acids. They have four levels of structural organization. Primary structure, the amino acid sequence (1˚ structure), which is connected by peptide bonds. Primary structure of polypeptide determines the higher levels of structural organization. Peptide bonds are amide linkages formed between α-amino group of one amino acid and the α-carboxyl group of another. The α-amino acids have α-carbon, to which one α-amino group (–NH2/N-terminal), one α-carboxylic group (–COOH/C-terminal) is attached, and one side chain (R group), which is different in each amino acid. Amino acids are classified based on their properties of the R-group of side chain, on the basis of their polarity, hydrophilicity, hydrophobicity, etc. at the physiological pH 7.
