5.1.2 Formation of Peptides of Proteins

Amino acids link in specific sequence to form strands of protein called peptides in which one amino acid is linked with the next amino acid by a peptide bond. The carboxyl (-COOH) group of one amino acid bonds to the amino (-NH2) group of another amino acid releasing one molecule of water and form a dipeptide. 

 

 If three amino acids are thus linked, it is a tripeptide and if many amino acids are liked they are called polypeptide.amino acids where as a polypeptide containing more than 10 amino acids are called proteins.

  • These polypeptide chains twist, fold or coil into different shapes in forming the proteins.

    Proteins present in the animal body perform various functions that include serving as carrier of vitamins, oxygen, carbon dioxide plus structural, kinetic, catalytic, and signaling roles.
