Τι (ποιος) είναι sterol - ορισμός

ANY ORGANIC COMPOUND THAT IS A STEROID HAVING A HYDROXYL GROUP ATTACHED TO C3 POSITION
Sterols; Zoosterol

sterol         
['st??r?l, 'st?r?l]
¦ noun Biochemistry any of a group of naturally occurring unsaturated steroid alcohols, typically waxy solids.
Origin
early 20th cent.: independent usage of the ending of words such as cholesterol.
Sterol carrier protein         
PROTEIN FAMILY
Sterol-binding domain
Sterol carrier proteins (also known as nonspecific lipid transfer proteins) is a family of proteins that transfer steroids and probably also phospholipids and gangliosides between cellular membranes.
Sterol O-acyltransferase         
CLASS OF ENZYMES
Acyl-CoA:cholesterol acyltransferase; Acyl CoA Cholesteryl Acyl Transferase; EC 2.3.1.26; Acyl-CoA cholesterol acyl transferase; Acyl-CoA cholesterol acyltransferase; Acyl-CoA acyltransferase; Acyl-CoA cholesterin acyltransferase; Acyl-CoA:cholesterol O-acyltransferase; Acyl CoA cholesteryl acyltransferase; Sterol o-acyltransferase
Sterol O-acyltransferase (also called Acyl-CoA cholesterol acyltransferase, Acyl-CoA cholesterin acyltransferase or simply ACAT) is an intracellular protein located in the endoplasmic reticulum that forms cholesteryl esters from cholesterol.

, whose molecule is derived from that of gonane by replacement of a hydrogen atom in position 3 by a hydroxyl group. It is therefore an alcohol of gonane. More generally, any compounds that contain the gonane structure, additional functional groups, and/or modified ring systems derived from gonane are called steroids. Therefore, sterols are a subgroup of the steroids. They occur naturally in most eukaryotes, including plants, animals, and fungi, and can also be 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.

While technically alcohols, sterols are classified by biochemists as lipids (fats in the broader sense of the term).

1. For those without high cholesterol, sterol products are less suitable as they interfere with the absorption of key nutrients.
