Abstract
- The effect of oxygen concentration at 1 atm on rat enzyme systems concerned in the synthesis and degradation of 5-hydroxytryptamine was studied in vitro. 2. Oxygen activated tryptophan hydroxylase and the deamination of both 5-hydroxytryptamine and tyramine by monoamine oxidase. 3. Oxygen did not affect the activities of 5-hydroxytryptophan decarboxylase or peroxidase.
摘要
- 在体外研究了1个大气压下氧气浓度对大鼠体内与5-羟色胺合成和降解相关的酶系统的影响。2. 氧气激活了色氨酸羟化酶以及单胺氧化酶对5-羟色胺和酪胺的脱氨基作用。3. 氧气不影响5-羟色氨酸脱羧酶或过氧化物酶的活性。
