Document Summary
Highly soluble in nonpolar solvents; most are amphipathic. Forms lipid bilayer, used for energy, and involved in cell communication (i. e. steroids) Classes of lipids: fatty acids (fa) formula r-cooh, triaglycerols (tg) fat storage ad thermal insulation, glycerophospholipids general membrane component, sphingolipids membrane component in the brain, waxes protection (found in cell walls, exoskeleton, skin) Can be saturated or unsaturated (contains at least one double bond) Saturated solid at room temp (higher mp); unsaturated liquid at room temp (lower mp) Trans fat making a saturated fat from an unsaturated fat; this introduces a lot of trans formation fat which is not healthy. Glycerol + 3 fa linked via ester bonds. Simple tg all fa chains are the same, mixed tg contains 2 or 3 different fa chains. Glycerol bound to 2 fa and a phosphate group (which can bind other groups i. e. sugar groups)
