What Is The Chemical Structure Of Lipids. The lipid part of the membrane is polar or amphipathic lipid largely phosphoglycerides some amounts of sphingolipids and a negligible amount of triacylglycerols. Both stearic acid a fatty acid and phosphatidylcholine a phospholipid are composed of chemical groups that form polar heads and nonpolar tails The polar heads are hydrophilic or soluble in water whereas the nonpolar tails are hydrophobic or insoluble in water. The lipids can be classified according to the chemical structure into the large group of heterogenous compounds as the following. There is great structural variety among the lipids as will be demonstrated in the following sections.
The structure of the fatty acids determines whether or not the fat is considered saturated or unsaturated. Complex lipids such as phospholipids. Waxes steroids phospholipids and fats are the most common types of lipid groups. Lipids are considerably smaller than proteins. The Chemical Classes of LipidsTheir Structure and Nomenclature. Structure of lipids.
Ether chloroform acetone benzene and general insolubility in water.
70 to 80 per cent are polar lipids and the remainder is mostly protein. Fats and oils the most common lipids in food are triacylglyceride mixtures ie. It can be found in large concentrations within the liver spinal cord and brain. You may click on a topic listed below or proceed page by page.
