Unformatted text preview: Four major classes of biomolecules Carbohydrates Proteins Lipids Nucleic Acids Lipids are a chemically diverse group of compounds Lipids are insoluble in water, but soluble in aprotic organic solvents including diethyl ether, chloroform, methylene chloride, and acetone Lipids include fatty acids, triacylglycerols, sphingolipids, phosphoacylglycerols, glycolipids, lipid-soluble vitamins prostaglandins, leukotrienes, and thromboxanes cholesterol, steroid hormones, and bile acids The function of lipids is as diverse as their chemistry Major types of lipids Fatty acids Storage lipids Triacylglycerols Membrane lipids Phospholipids Glycerophospholipids Sphingolipids Glycolipids Sphingolipids Isoprenoids Sterols Simplest lipids are fatty acids Saturated versus unsaturated fatty acids CH 3-(CH 2 ) 14-C-OH = O CH 3-(CH 2 ) 5-CH=CH-(CH 2 ) 7-C-OH = O Naturally occurring fatty acids Double bonds can be in one of two configurations trans cis Fatty acids with cis double bonds are kinky ..and form less stable aggregates Common derivatives of fatty acids CH 3-(CH 2 ) 5-CH-CH-(CH 2 ) 7-C-OH = O CH 2 CH 3-CH-(CH 2 ) 4-CH=CH-(CH 2 ) 7-C-OH = O CH 3 Major types of lipids...
