Search this article

Description

A steep decrease in value of specific rotation was observed when concentration of sulfuric acid reached more than constant normality for each amino acid. Ultraviolet ab-sorption, nuclear magnetic resonance and Raman spectra showed that these decrease of specific rotation in concentrated sulfuric acid are attributed to the protonation of carboxyl group. The concentration of sulfuric acid in which amino acids showed maximum specific rotation are as follows.<br> Amino Acids Normality of sulfuric acids<br> L-Arginine 10 to 11<br> L-Aspartic acid 2 to 3<br> L-Isolcucine 20<br> L-Leucine 20<br> L-Phenylalanine 18<br> L-Valine 20
