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 ยป 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.

... link to the source that you get the resource from. So if you find the paper through pubmed but you view and download the PDF form the Journal of Lipid Research (JLR), you must use the JLR link.

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 ...

Propagation and Transfection of BHK cells?

... :? (i.e. which condition will produce MMP9 expressing cells) 3 conditions: A. Untransfected cell (growth media only) B. Control transfected cells (lipid alone, non-expressing) C. MMP-9 transfected cells (DNA and Lipid, expressing) Many thanks! :lol:
