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-L-丙氨酸和L-亮氨酸苄酯通过几种试剂。
