BIO 360 Chapter Notes - Chapter 17: Omicron, Apolipoprotein, Glycerol
Document Summary
Dietary fatty acids absorbed in vertebrate small intestine. Oxidation of fatty acids is a major energy source in many organisms. ~ 113 of our energy needs comes from dietary tri acyl glycerol s. ~ 80% of energy needs of mammalian heart + liver are met by oxidation of fatty acids. Many hibernating animals , such as grizzly bears , rely almost exclusively on fats as their source of energy. Lipids transported in the blood as chylomicrons. Fatty acids carry more energy per carbon (more reduced) Fatty acids carry less water because they are nonpolar. Glucose + glycogen short term energy needs + quick delivery. Fats long term (months) energy needs , good storage + slow delivery. Chyl omicron surface layer of phospholipids , head groups facing aqueous phase. Trlacylglycerol s sequestered in the interior lyellow) make up more than 80% of the mass.
