Document Summary
Biochem423/523 - lecture 12 - hydrocarbons and membrane additives. The membrane is made up of lipids (glycerophospholipids in a bilayer form) Naturally occurring fatty acids contain an even number of carbon atoms. If double bonds are present (unsaturation), they are usually in the cis conformation. Saturated fatty acids do not have any double bonds, or kinks, in their hydrocarbon chain. Polyunsaturated fatty acids (pufa) contains two or more double bonds in the hydrocarbon chain. Storage of fatty acids in organisms is largely in the form of triacylglycerols, or triglycerides (fats) They are triesters of fatty acids and glycerol. Hydrogenation preserves some foods and prevents spoilage. Adipocytes are animal cells specialized for containing fat droplets, and make up most of. It serves three main purposes: energy production, heat production, and insulation the adipose (fatty) tissue. Saponification is the process of hydrolyzing fats with bases such a naoh or koh.
