Document Summary

By the end of this topic, you should be able to: describe and distinguish between different classes of lipids. The new added carbon bond is cis and results in a kink in the molecule. Fatty acids are written in the short form with number of carbons bonds with the number of double bonds separated by a colon. (ex 16:0) fatty acids are used for energy and structure. Triacylglycerols are three carbon molecules with hydroxyl group at each carbon end. To make triacylglycerol the hydroxyl group end is attached to a fatty acid using an ester bond. Glycerophospholipids are like triacylglycerols but one end on the fatty acids is replaced with a phosphate group. The phosphate group is usually conjugated (double/triple bonds separated with single bonds in between) to a polar alcohol. If a fatty acid is attached to nitrogen of sphingosine with amide linage than molecule is a ceramide.
