〔答〕血清类脂质检查用于肝脏方面的有总胆固醇和胆固醇脂.人体内胆固醇可由乙酰辅酶A合成.肝脏是人体合成胆固醇的主要器官,肠壁细胞、皮肤、肾上腺皮质、性腺也能合成少量胆固醇.肝脏不仅合成胆固醇速度最快,还能迅速地将胆固醇以脂蛋白形式输送到血液中.肝脏在胆固醇代谢上起重要作用的表现在:(1)肝脏能充分利用乙酰辅酶A合成胆固醇和胆固醇脂.(2)肝脏能合成卵磷脂胆固醇酰基移换酶,该酶到血液后能使血浆内卵磷脂分子上的脂肪酸与游离型胆固醇合成胆固醇脂.
〔A〕 Serum lipid test for the liver with total cholesterol and cholesterol, cholesterol in the human body can be synthesized by acetyl-CoA, the liver is the body’s main organ for the synthesis of cholesterol, intestinal cells, skin, adrenal cortex, gonads can Synthesis of a small amount of cholesterol, the liver is not only the fastest cholesterol synthesis, but also quickly to cholesterol in the form of lipoprotein delivery to the blood.The liver plays an important role in cholesterol metabolism in the performance of: (1) the liver can make full use of acetyl-CoA synthesis Cholesterol and cholesterol. (2) The liver can synthesize lecithin cholesterol acyltransferase, the enzyme to the blood plasma lecithin molecular fat and free cholesterol synthesis of cholesterol.
