CLASSIFICATION OF LIPIDS Lipids are classified as follows: 1. Simple lipids: Esters of fatty acids with various alcohols. (a) Fats: Esters of fatty acids with glycerol. Oils are fats in the liquid state. A long-chain carboxylic acid; those in animal fats and vegetable oils often have 12–22 carbon atoms. (b) Waxes: Esters of fatty acids with higher molecular weight monohydric alcohols. Waxes are carboxylic acid esters, RCOOR’ ,with long, strai…

LIPIDS The lipids are a heterogeneous group of compounds, including fats, oils, steroids, waxes, and related compounds, which are related more by their physical than by their chemical properties. Lipids are non-polar (hydrophobic) compounds, soluble in organic solvents. Most membrane lipids are amphipathic, having a non-polar end and a polar end Lipids are important in biological systems because they form the cell membrane, a mechanical barrier that divi…

Diclofenac Short half life (1‐2 hrs), high 1stpass metab.,  accumulates in synovial fluid after oral admn., reduce inflammation, such as in arthritis or acute injury Mechanism of action inhibition of prostaglandin synthesis by inhibition of cyclooxygenase (COX). There is some evidence that diclofenac inhibits the lipooxygenase pathways, thus reducing formation of the leukotrienes…
