Abstract
The effect of alkali treatment on the isomerization of amino acids was investigated. The 100×D/(D+L) values of amino acids from peptide increased with increase in the number of constituent amino acid residues. Furthermore, the N-terminal amino acid of a dipeptide was isomerized to a greater extent than the C-terminal residue.
摘要
研究了碱处理对氨基酸消旋化的影响。随着组成氨基酸残基数目的增加，来自肽的氨基酸的 100×D/（D+L）值增加。此外，二肽的 N 末端氨基酸比 C 末端残基更容易发生消旋化。
