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

Identical a chain Identical b chain
Lysine = C6H14N2O2 = 149.5 m/g
Proline = C5H9NO2 = 117.25 m/g
Valine = C5H11NO2 = 119.75 m/g
Glycine = C2H5NO2 = 76.25 m/g
Lysine = C6H14N2O2 = 149.5 m/g
Total = 612.25 = Identical a chain
Lysine = C6H14N2O2 = 149.5 m/g
Arginine = C6H14N4O2 = 177.5 m/g
Arginine = C6H14N4O2 = 177.5 m/g
Valine = C5H11NO2 = 119.75 m/g
Glycine = C2H5NO2 = 76.25 m/g
Total = 700.5 = Identical b chain
For example
= a2 + b2 = c2
= a2 = Identical a chain and b2 = Identical b chain = c2
= a2 = 612.25 and b2 = 700.5 = c2
= a612.25 + b700.5 = c2
= 374850.0625 + 490700.25 = c2
= a + b = 865550.3125 = c2
= a + b = 865550.3125 / 930.3 = 930.3
= a + b = 930.3 = Polypeptide
= a + b = 930.3 / 64 (S2) = 14.5359375 = cross-linked of Sulfur oxide
= a + b = 14.5359375 * 6.8 (Hemoglobin Iso pH) = 98.844375
= a + b = 98.84 + 13.16 CH = 112
= a + b = 112 = Residues
= a + b = 930.3 / 64 (S2) = 14.5359375 = cross-linked of Sulfur oxide
= a + b = 14.5359375 * 7 (Myoglobin Iso pH) = 101.7515625
= a + b = 101.75 + 13.25 CH = 115
= a + b = 115 = Residues
= a + b = 930.3 * 69.33 (2CH2OH + H4) = 64497.699
= a + b = 64497.699 + 2.301 H2 = 64500
= a + b = 64500 = molecular weight of (Hemoglobin)
= a + b = 930.3 = Polypeptide
= a + b = 930.3 / 20.55 (H2O + H2) = 45.27
= a + b = 45.25 = COOH = carboxyl-group,
= a + b = 930.3 = Polypeptide
= a + b = 930.3 / 21.14 (H2O + H2) = 44.00
= a + b = 44.00 = carboxyl-terminal end
= a + b = 930.3 = Polypeptide
= a + b = 930.3 / 128 (S4) = 7.26796875
= a + b = 7.26796875 - 0.46796875 (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 / 930.3 Polypeptide = 17942.79
