Hope this helps!

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 \(NH_2\) (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)
