Name two physical properties that characterize matter.
Biochem 2 Review 3 Chapter 20: lipid metabolism Triacylglycerols (triglycerides/fats) - Storage and transport form of fats - highly concentrated energy storage molecule, so therefor the major form of energy storage in people - when fully oxideized to CO2 and water, it gives over twice the energy per carbon than glucose. - Stored in adipose tissue, and undergo beta-oxidation to give acetyl CoA, FADH2 and NADH. Lipid Digestion - Takes place at lipid-water interfaces because fats are hydrophobic but enzymes are hydrophilic. - The rate of the reaction is determined by surface area of interface, so bile salts are released to increase the surface
