Abstract
- The incorporation and washout of [1-14C]palmitate in the subcellular fractions of toad, chick and guinea-pig hearts has been studied at warm and cold temperatures. 2. Maximal FFA radioactivity generally occurred in the microsomal fraction. Washout of radioactivity in chick and guinea-pig hearts virtually ceased in the cold, while in the toad it was only moderately affected. 3. The microsomal esterification process was temperature dependent. It was most active in the guinea-pig and least active in the toad.
摘要
- 研究了在温暖和寒冷温度下，[1-14C]棕榈酸盐在蟾蜍、鸡和豚鼠心脏亚细胞组分中的掺入和洗脱情况。2. 游离脂肪酸（FFA）放射性最高值通常出现在微粒体组分中。鸡和豚鼠心脏中的放射性洗脱在寒冷环境下几乎停止，而蟾蜍心脏中的放射性洗脱仅受到适度影响。3. 微粒体酯化过程依赖于温度。在豚鼠中最活跃，在蟾蜍中最不活跃。
