Answer: Amino acids are the building blocks of proteins.

There are 20 standard amino acids which make up the human and other mammalian proteins. In a protein molecule, amino acids are held together by peptide bond which is formed between -COOH (carboxylic group) of one amino acid and [tex]NH_2[/tex] (amino group) of another amino acid.

They can be broadly divided as-

1) Charged amino acids

Lysine (K)

Arginine (R)
Aspartic acid (D)
Glutamic acid (E)

2) Hydrophobic amino acids

Glycine (G)
Alanine (A)
Proline (P)
Leucine (L)
Isoleucine (I)
Methionine (M)
Phenylalanine (F)
Valine (V)

3) Polar amino acids

Glutamine (Q)
Histidine (H)
Asparagine (N)
Serine (S)
Threonine (T)
Cysteine (C)
Tyrosine (Y)
Tryptophan (W)
