Application

胆固醇用于制备免疫刺激复合物以增强细胞和体液反应。它被掺入动物饲料中以研究富含胆固醇饮食的影响。
用于色谱的标准品

Biochem/physiol Actions

所有生物膜的主要成分；总脑脂质中约25%为胆固醇。
胆固醇是一种占到细胞膜结构成分约20-25％的脂质。它决定了膜的流动性和渗透性，使其可透过水而不是离子和质子。胆固醇还可调节质膜上存在的转运蛋白和信号蛋白的功能。胆固醇合成的主要部位是小肠和肝脏。

Preparation Note

胆固醇一水合物在热酒精中可产生透明无色至淡黄色的溶液。它还可溶于丙酮、二恶烷、乙酸乙酯、苯、石油醚、油、脂肪和胆盐的水溶液中。溶液应当避光保存。

Mycobacterium tuberculosis (Mtb) is the world's most deadly pathogen. Unlike less virulent mycobacteria, Mtb produces 1-tuberculosinyladenosine (1-TbAd), an unusual terpene nucleoside of unknown function. In the present study 1-TbAd has been shown to be a naturally evolved phagolysosome disruptor. 1-TbAd

Cholesterol Biosynthesis

Cholesterol biosynthesis starts in the hepatic endoplasmic reticulum with acetyl-CoA, yielding 3-hydroxy-3-methylglutaryl-CoA via HMG-CoA synthase.

胆固醇生物合成

胆固醇的生物合成通常发生在肝细胞的内质网中，并以乙酰辅酶A开始，乙酰辅酶A主要来源于线粒体中的氧化反应。乙酰辅酶A和乙酰乙酰辅酶A由HMG-辅酶A合成酶转化为3-羟基-3-甲基戊二酰辅酶A（HMG-辅酶A）。
