have . classification of lipids with lipid metabolism disorders. Clinical Biochemistry. ). Contrary to carbohydrates which constitute a family of relatively homogenous compounds, lipids form a very heterogenous class of compounds of widely differing structures and grouped according to their insolubility in water and solubility in organic solvents (ether, acetone, chloroform-alcohol mixtures, etc. They are arbitrarily classed together according to their solubility in organic solvent such as benzene, ether, chloroform, carbon terachloride (the so-called fat solvents) and their insolubility in water. The subjects of lipid nomenclature and classification are dealt with at many points in this website, but especially in relation to individual lipid classes as listed here.For definitive detailed accounts, we can serve you best by pointing to the following documents, which are all available in the form of PDF files as free downloads from the journals specified below. In this article we will discuss about the classification of lipids. No precise definition of the term lipid exists. Elena Ri.

Classification, functions and structure. Simple lipids: Esters of fatty acids with various alcohols. Lipid - Lipid - Classification and formation: There are four major classes of circulating lipoproteins, each with its own characteristic protein and lipid composition. 1. a . have . 5.3 CLASSIFICATION OF LIPIDS Lipids are classified as follows: 1. They naturally occur in most plants, animals, microorganisms and are used as cell membrane components, energy storage molecules, insulation, and hormones. The term “lipid” has been loosely defined as any of a group of organic compounds that are insoluble in water but soluble in organic solvents .These chemical features are present in a broad range of molecules such as fatty acids, phospholipids, sterols, sphingolipids, terpenes and others. 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. vneac. Fats and Lipids Definition: water insoluble compounds Most lipids are fatty acids or ester of fatty acid (TG) They are soluble in non-polar solvents such as petroleum ether, benzene, chloroform Classification: Neutral lipids (fatty acid esters of glycerol) Phospholipids, sphingolipids, and glycolipids (complex lipids) Clinical Biochemistry.
