residues are DL-alanine, L-valine, L-leucine, L-phenyl-alanine, L-proline, and L-serine have been synthesized and the separation of each glycyltripeptide diastereomers by an amino acid analyzer have been studied. Among six peptides studied, diastereomeric mixtures of H-Gly-DL-Ala-L-Val-OH and H-Gly-DL-Ala-L-Leu-OH were separated completely. A procedure to determine the amounts of LL and DL diastereomer
已经合成了几种三肽,H-Gly-DL-Ala-B-OH,其中 B 残基是
DL-丙氨酸、
L-缬氨酸、
L-亮氨酸、L-苯基-丙
氨酸、
L-脯氨酸和
L-丝氨酸,并且已经研究了通过
氨基酸分析仪分离每种甘
氨酰三肽非对映异构体。在研究的六种肽中,H-Gly-DL-Ala-L-Val-OH 和 H-Gly-DL-Ala-L-Leu-OH 的非对映异构混合物被完全分离。开发了使用分析仪测定 H-Gly-Ala-Leu-OH 的 LL 和 DL 非对映异构体量的程序,该程序用于检查偶联试剂对苄氧羰基偶联过程中外消旋化的影响-glycyl-
