There are basically three major classifications for amino acids (1) those with nonpolar R group, (2) those with uncharged polar R groups, and (3) those with charged polar R group. The table below shows us all 20 amino acids with their codes.
R-group Hydrocarbon Neutral Acid or base where the COOH is understood to be the carboxyl group shown above. There are 20 amino acids which make up the proteins, distinguished by the R-group. The simplest of the amino acids, glycine, has just H as an R-group. Amino acids are the structural elements from which proteins are built. When amino acids bond to each other, it is done in the form of an amide, making a connection which is called a peptide linkage. This can be illustrated with the two simplest amino acids, glycine and alanine.
