write a note on types of lipids
Answers
Explanation:
Simple Lipids
Esters of fatty acids with various alcohols.
Fats: Esters of fatty acids with glycerol. Oils are fats in the liquid state
Waxes: Esters of fatty acids with higher molecular weight monohydric alcohols
Complex Lipids
Esters of fatty acids containing groups in addition to alcohol and a fatty acid.
Phospholipids: These are lipids containing, in addition to fatty acids and alcohol, a phosphoric acid residue. They frequently have nitrogen-containing bases and other substituents, eg, in glycerophospholipids the alcohol is glycerol and in sphingophospholipids the alcohol is sphingosine.
Glycolipids (glycosphingolipids): Lipids containing a fatty acid, sphingosine and carbohydrate.
Other complex lipids: Lipids such as sulfolipids and amino lipids. Lipoproteins may also be placed in this category.
Precursor and Derived Lipids
These include fatty acids, glycerol, steroids, other alcohols, fatty aldehydes, and ketone bodies, hydrocarbons, lipid-soluble vitamins, and hormones. Because they are uncharged, acylglycerols (glycerides), cholesterol, and cholesteryl esters are termed neutral lipids. These compounds are produced by the hydrolysis of simple and complex lipids.
