Abstract
- The specific activity of the enzyme palmitoyl-CoA-l-glycerol 3-phosphate palmitoyltransferase (EC 2.3.1.15) in the mammary tissue of guinea pigs has been shown to increase 37-fold at parturition. 2. Increases also occur in tissue concentrations of glycerol 3-phosphate, CoA and free fatty acid, but not in that of acid-insoluble CoA. 3. The isolation and fatty acid composition of plasma triglyceride and of mammary-tissue free fatty acid, diglyceride and triglyceride are described. 4. The findings are discussed in relation to the regulation of milk fat synthesis.
摘要
- 已证明豚鼠乳腺组织中棕榈酰辅酶A - L - 甘油3 - 磷酸棕榈酰转移酶（EC 2.3.1.15）的比活性在分娩时增加37倍。2. 甘油3 - 磷酸、辅酶A和游离脂肪酸的组织浓度也会增加，但酸不溶性辅酶A的浓度不会增加。3. 描述了血浆甘油三酯以及乳腺组织游离脂肪酸、甘油二酯和甘油三酯的分离及脂肪酸组成。4. 结合乳脂肪合成的调节对这些发现进行了讨论。
