Document Summary

Ch6 - lipids, membranes, & the frist cells. Simple lipid consisting of a hydrocarbon chain bonded to a carboxyl group (-cooh) Type of bone b/w carbons in hydrocarbon chains is a key factor in lipid structure and function. When 2 carbons form a double bond, attached atoms found in a plane instead of a 3d tetrahedron cis c=c bond forms a kink Family of lipids distinguished by a bulky, four-ring structure. Differ from one another by the functional (or side groups) attached to different carbons in the rings. 3 fatty acids linked to a glycerol (3-c molecule) If the fatty acids are polyunsaturated, fat is an oil Formed by dehydration reaction, ester linkage b/w glycerol and fatty acid. Glycerol linked to phosphate group and 2 hydrocarbon chains. Polar head and non polar tail = amphipathic. Membranes keep damaging materials out, allow necessary materials to enter (selective permeable)
