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 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.

2022年7月29日 · Cholesterol comprises carbon, hydrogen, and oxygen. It is a waxy, fatty substance that is solid and white or light yellow. Its chemical formula is C 27 H 46 O. This means it has 27 atoms...

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 crucial role in regulating cell function.

2024年2月27日 · Understanding cholesterol molecular structure and managing risk factors through lifestyle changes and regular check-ups are essential for preventing complications like atherosclerosis and heart disease.

2022年5月14日 · Cholesterol is starting ingredient for the synthesis of the steroid hormones including progesterone, estrogens, androgens (e.g., testosterone), glucocorticoids (e.g., cortisol), and mineralocorticoids (e.g., aldosterone). Cholesterol is also the precursor from which the body synthesizes vitamin D.

There are mainly three components in the chemical structure of cholesterol. They are: Steroid Backbone: It is the core structure of cholesterol consisting of four fused hydrocarbon rings, say A, B, C, and D, as shown in the figure, which is the classic feature of all steroids.

Cholesterol plays a vital role in animal life, and it is essential both as a structural component of cell membranes and as a precursor of steroid hormones and bile acids in cells. It takes part in cell signalling, transport processes, nerve conduction and the regulation of gene transcription.

Cholesterol originated from the Greek words chole, which means bile, stereos, which means solid, and the suffix -ol, which means alcohol. As a sterol, it is an organic compound and a form of lipid. It is also a structural part of the animal cell membrane that all animal cells can biosynthesize.

Structure Of Cholesterol . As cholesterol is a cholestanoid with cholestane with a double bond at 5,6-position and a 3beta-hydroxy group. It plays the role of a human metabolite, mouse metabolite, an algal metabolite and a Daphnia galeata metabolite.
