PHOSPHATIDES Meaning and
Definition
-
Phosphatides, also known as phospholipids, are a type of lipid molecule that plays a crucial role in the structure and function of cell membranes. They are composed of a glycerol backbone, two fatty acid chains, a phosphate group, and a polar head group.
The structure of phosphatides allows them to form a bilayer arrangement in cell membranes, with the hydrophilic head groups facing the aqueous environment on either side and the hydrophobic fatty acids pointing inward, creating a barrier that separates the internal contents of the cell from the external environment. This bilayer structure provides the necessary flexibility and fluidity for cell membranes to perform essential functions such as regulating the passage of molecules in and out of the cell.
Phosphatides also serve as important signaling molecules in cellular processes. They can be enzymatically cleaved to produce secondary messengers such as diacylglycerol and inositol trisphosphate, which play pivotal roles in intracellular signaling pathways. These molecules can activate various cellular processes, including ion channel opening, gene expression, and cellular differentiation.
Furthermore, phosphatides are involved in the transport of lipids throughout the body. They form lipoproteins when combined with proteins, allowing for the transport of lipids, such as cholesterol and triglycerides, through the bloodstream to cells where they are needed.
In summary, phosphatides are essential components of cell membranes involved in maintaining cell structure, facilitating signaling pathways, and mediating the transport of lipids in the body.

Etymology of PHOSPHATIDES
The word "phosphatides" is derived from the combination of two words: "phosphate" and "lipids".
"Phosphate" comes from the Greek word "phosphoros", meaning "light-bringing", which is ultimately derived from "phos" (light) and "pherein" (to carry). Phosphorus, the element it refers to, was discovered by German alchemist Hennig Brand in 1669. Since phosphorus emits a pale glow in the dark, he named it "phosphoros" or "light-bringer".
"Lipids", on the other hand, originates from the Greek word "lipos", meaning "fat". The term was first introduced by the French chemist and pharmacist Michel Eugène Chevreul in the early 19th century to describe a class of organic compounds that are soluble in nonpolar solvents.
