Biochemistry (Fach) / Lipids (Lektion)
- fatty acids usually unbranched carboxylic acids (O=C-OH)
- unsaturated vs. saturated fatty acid unsaturated = double bonds
- glycolipid a carbohydrate bound to a hydroxygroup of a lipid by glycosidic linkage
- gangliosides glycolipids with complex carbohydrate moiety that cobtains more than 3 sugars and obe of them is sialic acid found in nerve tissues
- waxes complex ester long chain carboxylic acids
- steroids lipids with a fused-ring structure e.g cholesterol
- lipid soluble vitamins EDEKA
- odd numbered fatty acids also undergo ß-oxidation but the final product is propionyl coA whihc is then converted to succinyl-CoA
- Ketone Bodys Acetoacetate: alternative energy source, used by excess of acetyl-CoA (e.g by excessive intake of Fats) side product is acetone
- fatty acid biosynthesis not exact reverse of ß-ocidation, takes place in cytosol, requires energy
