phosphatidylcholine
[fษsfษหtaษชdษlหkoสliหn ]
Definition
biochemistry term
Phosphatidylcholine is a class of phospholipids that are a major component of biological membranes. They are composed of two fatty acid chains, a glycerol backbone, a phosphate group, and a choline head group, making them essential for cell structure and function. It is involved in various physiological functions, including membrane integrity, cell signaling, and lipid transport.
Synonyms
Examples of usage
- Phosphatidylcholine is vital for maintaining cell membrane structure.
- In the liver, phosphatidylcholine plays a role in lipid metabolism.
- Dietary sources of phosphatidylcholine include eggs and soybeans.
- Supplements containing phosphatidylcholine are marketed for liver health.

Origin of 'phosphatidylcholine'
Main points about word origin
- The word is derived from 'phos' meaning light, 'fat' referencing its lipid nature, and 'choline,' which is a nutrient.
- It was first recognized and named in the 1940s, highlighting the ongoing discovery of important cell components.
The term phosphatidylcholine originates from the combination of several Greek and Latin roots referring to its chemical structure. The 'phosphatid-' part derives from 'phosphor', indicating the presence of a phosphate group. The 'choline' part refers to the choline head group that is integral in its structure. Phosphatidylcholine was first identified in the early 20th century as a component of egg yolk and soybeans, where it was termed lecithin. Over time, research has highlighted its importance in molecular biology and human nutrition as an essential nutrient for the synthesis of membranes and neurotransmitters. Phosphatidylcholine has since been recognized for its potential health benefits and its role in cognitive function, cardiovascular health, and liver metabolism.
