Unlike carbohydrates, proteins and nucleic acids lipids aren’t polymers but small molecules, with a molecular weights that range between 100 and 5000, and also vary considerably in polarity, including hydrophobic molecules, like triglycerides or sterol esters, and others more water-soluble like phospholipids or very short-chain fatty acids, the latter completely miscible with water and insoluble in non polar solvents. 1. They may be classified based on their physical properties at room temperature (solid or liquid, respectively fats and oils), on polarity, or on their essentiality for humans, but the preferable classification is based on their structure.Based on structure, they can be classified in three major groups.

The LIPID MAPS classification system is based on the concept of 2 fundamental “building blocks”: ketoacyl groups and isoprene groups ().Consequently, lipids are defined as hydrophobic or amphipathic small molecules that may originate entirely or in part by carbanion based condensations of ketoacyl thioesters and/or by carbocation based condensations of isoprene units (). Its application to glycerol (VII) is particularly simple : CH~OH (3) VI1 Glycerol (sn numbering to right) 524 JOURNAL OF LIPID RESEARCH VOLUME 8, 1967 Nomenelatwe of Lipids by on June 18, 2008 www.jlr.org Downloaded from Acts as an emulsifier in fat digestion and absorption Triglyceride Phospholipid Cholesterol Important component of all cell membranes due to its hydrophilic head and hydrophobic tail.

As a result, the lipid components are arranged in a continuous . Knowledge of lipid biochemistry is necessary in understanding many important biomedical areas, e.g., obesity, diabetes mellitus, atherosclerosis, and the role of various polyunsaturated fatty acids in nutrition and health. The structure of the fatty acids determines whether or not the fat is considered saturated or unsaturated. Up Next.
