HYDROXYCHOLESTEROLS Meaning and
Definition
-
Hydroxycholesterols are a group of chemical compounds derived from cholesterol through hydroxylation, a process that adds a hydroxyl group (-OH) to the cholesterol molecule. It refers to a family of cholesterol metabolites that play important roles in various biological processes.
Hydroxycholesterols are primarily produced in the liver and are present in relatively low concentrations in the bloodstream. They act as intermediates in the biosynthesis of bile acids and steroid hormones. Moreover, these compounds serve as important regulators of cholesterol metabolism by influencing the expression and activity of enzymes involved in cholesterol synthesis and transport.
One of the most well-known hydroxycholesterols is 25-hydroxycholesterol, which serves as a precursor for cholecalciferol, also known as Vitamin D3. It is produced in the skin upon exposure to ultraviolet B (UVB) radiation and converted into its active form through various metabolic steps in the liver and kidneys.
In recent years, hydroxycholesterols have garnered significant attention due to their potential roles in various pathophysiological conditions. They have been implicated in the development and progression of atherosclerosis, a chronic inflammatory disease of the arteries that is a major cause of heart attacks and strokes. Additionally, hydroxycholesterols have been studied for their potential as biomarkers for certain diseases and as therapeutic targets for drug development.
In summary, hydroxycholesterols are cholesterol derivatives that play diverse roles in cholesterol metabolism and have emerged as important molecules in various physiological and pathological processes.

Etymology of HYDROXYCHOLESTEROLS
The word "hydroxycholesterols" is made up of two components: "hydroxy" and "cholesterols".
The term "hydroxy" comes from the Greek word "hydor" meaning "water" and the suffix "-oxy" meaning "related to oxygen". In this context, "hydroxy" refers to a compound that contains the hydroxyl group (–OH), which consists of an oxygen atom bonded to a hydrogen atom.
"Cholesterols" is derived from the word "cholesterol", which itself has its roots in the Greek words "chole" meaning "bile" (referring to its bile-like appearance) and "stereos" meaning "solid" (referring to its waxy texture).
Combining these components, "hydroxycholesterols" refers to compounds that are derived from cholesterol and have hydroxyl groups attached to their structure.
