| Abstract Spectroscopic studies in the U.V region were carried out on human PSA. The U.V spectra of PSA, was obtained and revealed that PSA have a characteristic spectrum. The effect of pH and polarity on PSA U.V spectra was studied. Spectrophotometric pH titration and solvent perturbation were carried out and the data revealed that about 83.3% of tyrosine residues are located on the surface of the PSA molecule, while about 16.7% of tyrosine residues are buried interior the folded structure of the PSA. About 27.4% of histidine residues is located on the surface of the PSA molecule, while about 72.6% of histidine residues is embedded in the interior region of the PSA molecule. | ||
