Hydroxyproline
Hydroxyproline
Hydroxyproline (pronounced: hy·droxy·pro·line) is an amino acid that is particularly important in collagen structure.
Etymology
The term "Hydroxyproline" is derived from the Greek words "hydro" meaning water, "oxy" referring to oxygen, and "proline", another amino acid from which it is derived.
Definition
Hydroxyproline is a non-essential, non-proteinogenic amino acid, which means it is produced in the body and is not directly involved in the creation of proteins. It is a major component of the protein collagen, the substance that holds together the skin and connective tissue in animals.
Function
Hydroxyproline plays a key role in maintaining the stability of collagen. It helps provide structure to connective tissues, skin, tendons, and ligaments. It also contributes to the integrity of the walls of blood vessels and other tissues throughout the body.
