Document Summary
Energy provided per greater than carbohydrates more carbons and hydrogens per. Instead of hydrogen atom, there is a double bond between the two carbons: saturated fats saturated with hydrogens, no double bonds, solid at room temperatures, mostly come from animal sources. The shorter a carbon chain is, the easier the fat is broken down. Hydrogenation solidifying unsaturated fats essentially adding hydrogens to break the double bonds and turn them into saturated fats. Cholesterol type of lipid, only from animal products, we can make it ourselves as well as eat it. Types of lipids: triglycerides glycerol and 3 fatty acids, fatty acids even number of carbons, can be saturated or unsaturated, omega-3 and omega-6 fatty acids 18-carbon polyunsaturated fatty acids. Polyunsaturated: more than one double bond in each fatty acid chain. Fatty acids: methyl group at one end carbon with 3 hydrogens. Acid group at the other end (carboxyl group: usually even number of carbons.
