Document Summary
Fatty acids are hydrocarbon derivative amphiphillic molecules so polar head and non-polar tail, with carboxyl head and fatty chain. In esterification they join glycerol to form triacylglycerol. Fat is a major energy store and catabolized in times of need, in aerobic exercise it releases massive energy because it is so reduced. Can be used for heat and hibernation for animals, and generates water too for survival. Linoleic= 18:2 delta 9,12 a-linoleic= 18:3 delta 9, 12, 15 y-linoleic= 18:3 --- Glucagon stimulates it"s breakdown and hormones trigger the mobilization of it by activating the gs pathway coupled with gpcr when hormone binds, this releases the 2 catalytic pka subunits from the regulatory subunits once camp binds. Amp can also signal mobilization of fatty acids out of adipocytes when other catabolic pathways are on. Fatty acids first activated by linking to coa via thioester bond.
