BIOL 2021 Lecture Notes - Lecture 3: Carnitine O-Palmitoyltransferase, Lipoprotein Lipase, Acetyl-Coa
Document Summary
Important for migratory birds who fly incredibly long distances: ruby-throated hummingbird winters in. Central america and nests in southern canada often flies non-stop! Must go through many more oxidation steps than carbohydrates before completely broken down to co2. * fats have 9 calories/g whereas carbohydrates have 4 calories/g (alcohol = 7 cal/g) Fatty acids released from tags, transported to cytoplasm and then mitochondria of peripheral tissues (muscle cells) for degradation. Oxidation: 4 step process, yields acetyl-coa units that feed into the. When too much fuel is around, fatty acids are made, linked to glycerol (tags are made) and stored in adipocytes: localization of processes: Fatty acids need to be delivered to cells for. Two major sources for fatty acids (fa) and glycerol for metabolic fuels are obtained from triacylglycerols: (1) in the diet (2) stored in adipocytes (fat storage cells) Free fatty acids occur only in trace amounts in cells. Storage and mobilization of fatty acids in fat cells.
