LIPIDS NOTES BY BILAL MALIK 163 LIPIDS: • Lipids (fixed oils, fats, and waxes) are esters of long-chain fatty acids and alcohols, or of closely related derivatives. They are grouped together on the basis of their solubility in non polar solvents. pharmakon - drugs gnosis - knowledge. They may also be glyceroglycolipids or sphingoglycolipid depending upon the alcohol group present (glycerol or sphingosine). Steroid derivatives are phenanthrene structures that are quite different from lipids made up of fatty acids. The general empirical structure for carbohydrates is (CH 2 O) n.; They are organic compounds organized in the form of aldehydes or ketones with multiple hydroxyl groups coming off the carbon chain.
