1 Lipids Definition Classification Functions Lipid Chemistryо Recent news. lipid, any of a diverse group of organic compounds including fats, oils, hormones, and certain components of membranes that are grouped together because they do not interact appreciably with water. one type of lipid, the triglycerides, is sequestered as fat in adipose cells, which serve as the energy storage depot for organisms and. Classification of lipids. lipids can be classified according to their hydrolysis products and according to similarities in their molecular structures. three major subclasses are recognized: 1. simple lipids (a) fats and oils which yield fatty acids and glycerol upon hydrolysis. (b) waxes, which yield fatty acids and long chain alcohols upon.
Biology Revision Notes On Lipids Classification And Functions #biochemistry#lipidchemistrythis video includes definition, classification with examples and functions of lipids. useful for first year mbbs, occupational th. Lipids formed from fatty acids. fatty acids are carboxylic acids with 12 22 carbon atoms connected in a long, unbranched chain. as shown in the diagram above, most lipids are classified as esters or amides of fatty acids. waxes are esters formed from long chain fatty acids and long chain alcohols. most natural waxes are mixtures of such esters. Introduction. fats and lipids are an essential component of the homeostatic function of the human body. lipids contribute to some of the body’s most vital processes. lipids are fatty, waxy, or oily compounds that are soluble in organic solvents and insoluble in polar solvents such as water. lipids include:. The final category is the polyketides (pk), which are a diverse group of metabolites from animal, plant and microbial sources. fig. 1. lipid building blocks. the lipid maps classification system is based on the concept of 2 fundamental biosynthetic “building blocks”: ketoacyl groups and isoprene groups. fig. 2.

These lipids have enormous structural variability given the large number of different fatty acids (both saturated and unsaturated) and head groups that can be attached to a phosphate attached to the carbon 3 of glycerol. the structures of the most common glycerophospholipids are shown in figure 10.1.16 10.1. 16. The major saponifiable lipids are triacylglycerides, glycerophospholipids, and the sphingolipids. the first two use glycerol as the backbone. triacylglycerides have three fatty acids esterified to the three ohs on glycerol. glycerophospholipids have two fatty acids esterified at carbons 1 and 2, and a phospho x groups esterified at c3.
