Amino Acid Sequence of Polypeptide Chain:
The next important landmark was the identification of the amino acid sequence of the two types polypeptide in crystalline hemoglobin,
This was the first sequence **ysis of oligomeric or multichain proteins,
The hemoglobin contain on 4 polypeptide chain
Polypeptide = identical a chain = 141 residues
Polypeptide = identical b chain = 146 residues
The Human Adrenocorticotrophin and S – S linkage
1 polypeptide = Ser, Tyr, Ser, Met, Glu, His, Phe, Arg, Trp, Gly = 10 amino acids
2 polypeptide = Lys, Pro, Val, Gly, Lys, Lys, Arg, Arg, Pro, Val = 10 amino acids
3 polypeptide = Lys, Val, Tyr, Pro, Asp, Ala, Gly, Glu, Asp, Gln = 10 amino acids
4 polypeptide = Ser, Ala, Glu, Ala, Phe, Pro, Leu, Glu, Phe, = 9 amino acids
The longest polypeptide chains for which complete amino acids sequence have been deduced to date are those of bovine trypsinogen (229 residues) and bovine chymotrypsinogen (245 residues) and the polypeptide chain of glyceraldehydes 3-phosphate dehydrogenase of lobster muscles (333 residue) Although the amino acids sequence of over 50 different proteins are known,
The Bovine ribonuclease and S – S linkage
1 polypeptide = Lys, Glu, Thr, Ala, Ala, Ala, Lys, Phe, Glu, Arg = 10 amino acids

Threonine = C4H9NO3 = 121.25 m/g
Alanine = C3H7NO2 = 90.75 m/g

Alanine = C3H7NO2 = 90.75 m/g
Lysine = C6H14N2O = 149.5 m/g
Phenylalanine = C9H11NO2 = 167.75 m/g
