Cholesterol is a cholestanoid consisting of cholestane having a double bond at the 5,6-position as well as a 3beta-hydroxy group. It has a role as a human metabolite, a mouse metabolite, a Daphnia galeata metabolite and an algal metabolite. It is a 3beta-sterol, a cholestanoid, a C27-steroid and a 3beta-hydroxy-Delta (5)-steroid.

Cholesterol is the principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils. [3] [4] Cholesterol is biosynthesized by all animal cells [citation needed] and is an essential structural and …

Cholesterol is transported in the circulatory system and to the body tissues by plasma lipoproteins, which share a common structure of a neutral lipid core consisting of triglycerides and cholesterol esters, surrounded by a monolayer of phospholipids, free …

2022年7月29日 · Cholesterol’s structure consists of: The four hydrocarbon rings join together in the middle of the compound. The hydrocarbon tail attaches to one end, and the hydroxyl group attaches to the...

In blood, cholesterol is carried as a complex with lipoproteins, partly esterified with a fatty acid, and partly with the 3-0H free. (See Chapter 7, page 119). The cholesterol in blood can exchange readily with liver cholesterol, but some cholesterol pools, especially that in …

The 2D chemical structure image of cholesterol is also called skeletal formula, which is the standard notation for organic molecules.

Three structurally distinct regions are shown as shaded boxes: the 3β-hydroxyl group, the rigid steroid ring, and the flexible alkyl chain. The 3β-hydroxyl moiety is the only polar group in...

Cholesterol has vital structural roles in membranes and in lipid metabolism in general with an extraordinary diversity of biological roles, including cell signaling, morphogenesis, lipid digestion and absorption in the intestines, reproduction, stress responses, sodium and water balance, and calcium and phosphorus metabolism, and we can only tou...

2022年1月1日 · Cholesterol is synthesized by all animal cells and is an essential structural component of animal cell membranes, where it contributes to the order of phospholipid chains and overall membrane (dis)order, integrity and heterogeneity.

2023年8月8日 · Cholesterol is a structural component of cell membranes and serves as a building block for synthesizing various steroid hormones, vitamin D, and bile acids. Besides their structural role providing stability and fluidity, cholesterol also plays a …
