摘要

运用KrF激光光解瞬态吸收光谱、以丙酮为光敏剂研究了水溶液中色氨酰酪氨酸（Trp-Tyr）二肽的光化学过程，观察到丙酮三重态引发肽分子内的电子转移，由Trp/N,•,-Tyr→Trp-Tyr/O,•,自由基的生成过程。

Abstract

The photochemical reaction processes of triplet acetone with a peptide containing tryptophan and tyrosine residues (Trp-Tyr) were investigated in neutral aqueous solution using KrF (248nm) laser flash photolysis. Triplet acetone induced radical transformation: Trp/N,•,-Tyr→Trp-Tyr/O,•, was observed directly, and the transformation resulting from intramolecularelectron transfer was suggested.
