mushroom tyrosinase are reported. The enantiomers L-tyrosine, DL-tyrosine, D-tyrosine, L-dopa, DL-dopa, D-dopa, L-alpha-methyldopa, DL-alpha-methyldopa, L-isoprenaline, DL-isoprenaline, L-adrenaline, DL-adrenaline, L-noradrenaline, and D-noradrenaline were assayed with tyrosinase immobilized on a chiral support (sorbitol cinnamate), whereas L-tyrosine, DL-tyrosine, D-tyrosine, L-dopa, DL-dopa, D-dopa, L-alpha-methyldopa

of adrenaline toward hydrogenabstraction by the tert-butoxyl radical and the excited tripletstate of benzophenone have been examined in solution using laser flash photolysis techniques. The rate constants obtained in acetonitrile-rich solvents are 13 and 1.5 x 10(8) M(-1) s(-1) for benzophenonetriplet and the tert-butoxyl radical, respectively. Adrenaline is a better hydrogen donor than phenol, but
已使用激光闪光光解技术检查了溶液中肾上腺素对叔丁氧基自由基夺氢的反应性和二苯甲酮的激发三重态。对于二苯甲酮三重态和叔丁氧基,在富含乙腈的溶剂中获得的速率常数分别为13和1.5 x 10(8)M(-1)s(-1)。肾上腺素是比苯酚更好的氢供体,但效率不如α-生育酚。
