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

Identical a chain Identical b chain
Lysine = C6H14N2O2 = 149.5 m/g
Valine = C5H11NO2 = 119.75 m/g
Tyrosine = C9H11NO3 = 183.75 m/g
Proline = C5H9NO2 = 117.25 m/g
Aspartic acid = C4H7NO4 = 134.75 m/g
Total = 705 = Identical a chain
Alanine = C3H7NO2 = 90.75 m/g
Glycine = C2H5NO2 = 76.25 m/g
Glutamate = C5H9NO4 = 149.25 m/g
Aspartic acid = C4H7NO4 = 134.75 m/g
Glutamine = C5H10N2O3 = 148.5 m/g
Total = 599.5 = Identical b chain
For example
= a2 + b2 = c2
= a2 = Identical a chain and b2 = Identical b chain = c2
= a2 = 705 and b2 = 599.5 = c2
= a705 + b599.5 = c2
= 497025 + 359400.25 = c2
= a + b = 856425.25 = c2
= a + b = 856425.25 / 925.4 = 925.4
= a + b = 925.4 = Polypeptide
= a + b = 925.4 / 64 (S2) = 14.459375 = cross-linked of Sulfur oxide
= a + b = 14.459375 * 6.8 (Hemoglobin Iso pH) = 98.32375
= a + b = 98.32375 + 13.67625 CH = 112
= a + b = 112 = Residues
= a + b = 925.4 / 64 (S2) = 14.459375 = cross-linked of Sulfur oxide
= a + b = 14.459375 * 7 (Myoglobin Iso pH) = 101.215625
= a + b = 101.215625 + 13.784375 CH = 115
= a + b = 115 = Residues
= a + b = 925.4 * 69.69 (2CH2OH + H5) = 64491.126
= a + b = 64491.126 + 8.874 H7 = 64500
= a + b = 64500 = molecular weight of (Hemoglobin)
= a + b = 925.4 = Polypeptide
= a + b = 925.4 / 20.45 (H2O + H2) = 45.27
= a + b = 45.25 = COOH = carboxyl-group,
= a + b = 925.4 = Polypeptide
= a + b = 925.4 / 21.03 (H2O + H2) = 44.00
= a + b = 44.00 = carboxyl-terminal end
= a + b = 925.4 = Polypeptide
= a + b = 925.4 / 128 (S4) = 7.2296875
= a + b = 7.2296875 - 0.4296875 (H) = 6.8
= a + b = 6.8 Iso-electric pH of hemoglobin by 4 sulfur linkage
Carboxyl-group = COOH = 45.25 * 12 activate carbon atom = 543
= 543 + 49 [3(OH ion)] = 592

Supposed a cell function = 16692180 numbers / 925.4 Polypeptide = 18037.79
= 18038 / 1752 light sec = 10.29
