The photochemical lability of peptides is poorly understood, largely because of the lack of product data. In the present study, product analyses have been carried out following the photolyses in aqueous solution of selected glycyl dipeptides (Gly-Gly, DL-AIa-GIy, L-VaI-GIy, L-Pro-Gly, L-Phe-Gly, and Gly-L-Phe), L-prolyl-L-phenylalanine, and L-phenylalanyl-L-proline. Efficient deamination and decarboxylation
人们对肽的光化学不稳定性知之甚少,主要是因为缺乏产品数据。在本研究中,在选定的甘氨酰二肽(Gly-Gly、DL-Ala-Gly、L-Val-Gly、L-Pro-Gly、L-Phe-Gly、和 Gly-L-Phe)、L-脯氨酰-L-苯丙氨酸和 L-苯丙氨酰-L-脯氨酸。脂肪族二肽的有效脱氨基和脱羧在涉及肽键的光诱导电子转移过程中产生简单酰胺的热前体。苯丙氨酰肽光降解的类似途径受到其他类型反应的竞争。
