What exactly are lipids?
Answers:
Generally speaking, they're known to be fat. If you Google lipids you will find lots of info, but here's a site which includes a quiz http://www.chem4kids.com/files/bio_lipid…
These are fat and cholesterol. Cholesterol is a substance, but it is attached to carrier protein complexes call LDL, HDL, VLDL, and and then there is total cholesterol.

Lipid is a broadly used term, with a narrow interpretation as fat, which are fatty acid triglycerides.
Lipids are a broad group of naturally-occurring molecules which includes fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and others. The prime biological functions of lipids include energy storage, as structural components of cell membranes, and as important signaling molecules.
Lipids may be divided into eight categories: fatty acyls, glycerolipids, glycerophospholipids, sphingolipids, saccharolipids and polyketides (derived from condensation of ketoacyl subunits); and sterol lipids and prenol lipids (derived from condensation of isoprene subunits).
Although the permanent status lipid is sometimes used as a synonym for fats, fats are a subgroup of lipids called triglycerides. Lipids also encompass molecules such as fatty acids and their derivatives (including tri-, di-, and monoglycerides and phospholipids), as in good health as other sterol-containing metabolites such as cholesterol.
Most of the above was abstracted from the Wikipedia article on lipids Source(s): http://en.wikipedia.org/wiki/Lipid
