Document Summary
A large group of molecules that are not soluble in water. What makes thing soluble in water: water + glucose (sharing electrons) Water + fatty acids (repel sharing electrons) Diverse class of molecules that are insoluble in water. Lipids in the diet consist of: triglycerides: (solid fats & oils) with glycerol + 3 fatty acids. Usually what were talking about when we say fat : phospholipids: (eg. lecithin) We eat triglycerides and store our body fat as triglycerides. Made of: 1 glycerol molecular glycerol backbone , 3 fatty acid molecules long hydrophobic chains of carbon and hydrogen. Different fatty acids give triglycerides different properties. Fatty acids can be different: lengths- of their carbon chain. How it is digested and processed in the body. Fatty acids with different saturation (the way we classify fatty acids) Saturated (sfa)= no double bond (have hydrogen atoms surrounding every carbon in the chain)
