Lipid

Definition

noun, plural: lipids

A fatty or waxy organic compound that is readily soluble in nonpolar solvent (e.g. ether) but not in polar solvent (e.g water). Its major biological functions involve energy storage, structural component of cell membrane, and cell signaling.


Supplement

Examples of lipids are waxes, oils, sterols, cholesterol, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides (fats), and phospholipids.

Fatty acids (including fats) are a subgroup of lipids, hence, it will be inaccurate to consider the terms synonymous.


Word origin: French lipide » Greek lipos, fat.

Related forms: lipidic (adjective).
Related terms: glycolipids, lipid a, lipid bilayer, lipid granulomatosis, lipid peroxidation, lipid pneumonia, lipid profile, phospholipids, sphingolipids

Compare: fatty acid.

Main Factors that Affect Clinical Consequence of Toxicity

... factors that affect toxicosis. The chemical nature of a toxicant determines solubility, which in turn influences absorption, because nonpolar or lipid-soluble substances tend to be more readily absorbed than polar or ionized substances. The vehicle or carrier of the toxic compound also affects ...

... often a effective method to break down protienacious cellular walls or viral capsids and the using of a detergent such as SDS is viable to remove lipid membranes. Besides, DNA associated with other cellular proteins can be degraded with the addition of a protease. What’s more, the precipitation ...

Re: Elastic cytoplasm film.

It sounds like a black lipid membrane system is the sort of system you are looking for. However, the membranes are fairly unstable, so I doubt you could set one up that would last for months. http://en.wikipedia.org/wiki/Model_lipid_bilayer

Re: Elastic cytoplasm film.

I don't know what a "cytoplasm film" would be. A black membrane system comes to mind, in which a planar phospholipid bilayer is formed by painting the phospholipids across a small aperture in a rigid sheet separating two chambers containing aqueous solutions. Such a system ...
