Cholesterol

CAS No. : 57-88-5

MCE 国际站：Cholesterol

产品活性：Cholesterol 是一种哺乳动物中的主要固醇，占质膜结构成分的 20-25％。 质膜对水具有高渗透性，但对离子和质子则相对不可渗透。Cholesterol 在确定膜的流动性和渗透性特征以及转运蛋白和信号蛋白的功能中起着重要作用。Cholesterol 还是一种内源性雌激素相关受体 α (ERRα) 激动剂。

研究领域：Vitamin D Related/Nuclear Receptor  |  Metabolic Enzyme/Protease  |  Anti-infection

作用靶点：Liposome  |  Estrogen Receptor/ERR  |  Endogenous Metabolite  |  Bacterial

结构分类：甾体类  |  结构分类

In Vitro: GT1-7 hypothalamic cells subjected to Cholesterol depletion in vitro produced 20-31% reductions in cellular Cholesterol content. All Cholesterol-depleted neuron-derived cells, exhibit decreased phosphorylation/activation of IRS-1 and AKT following stimulation by insulin, insulin-like growth factor-1, or the neurotrophins (NGF and BDNF). Reduction in cellular Cholesterol also results in increased basal autophagy and impairment of induction of autophagy by glucose deprivation.

In Vivo: Cholesterol can be used in animal modeling to construct a rat model of hyperlipidemia.

Insulin-deficient diabetes in mice can lead to a reduction in brain Cholesterol synthesis, which occurs through a change in expression of Cholesterol synthesis enzymes and their upstream regulators SREBP2 and SCAP1.
The pool of Cholesterol in the whole animal is 2,200 mg/kg body weight. This is true for essentially all species from the mouse to the primate and indicates that the average concentration of Cholesterol in the whole animal is 2.2 mg/g fresh tissue.
The basal metabolic rate in the mouse is 170 kilocalories (kcal)/day/kg, and the flow of Cholesterol from all peripheral organs to the liver is greater than 100 mg/day/kg.
