Question

sterol vs steroid explain

Answer 1

Sterols, also known as steroid alcohols, are a subgroup of the steroids and an important class of organic molecules. They are a type of lipid. They occur naturally in plants, animals, and fungi, and can be also produced by some bacteria (however likely with different functions).The most familiar type of animal sterol is cholesterol, which is vital to cell membrane structure, and functions as a precursor to fat-soluble vitamins and steroid hormones.

Sterol chemical structure.

Types

Sterols of plants are called phytosterols and sterols of animals are called zoosterols. The most important zoosterol is cholesterol; notable phytosterols include campesterol, sitosterol, and stigmasterol. Ergosterol is a sterol present in the cell membrane of fungi, where it serves a role similar to cholesterol in animal cells.

Steroids

Steroids are a man-made version of chemicals, known as hormones, that are made naturally in the human body. Steroids are designed to act like these hormones to reduce inflammation. They're also known as corticosteroids, and are different to anabolic steroids used by bodybuilders and athletes.Steroids work by decreasing inflammation and reducing the activity of the immune system. They are used to treat a variety of inflammatory diseases and conditions. Corticosteroids are different from anabolic steroids, which some athletes use to build bigger muscles.
