Document Summary
Lipid synthesis and degradation pathways: biological significance, regulation under different conditions. Lipids have a bad reputation but are impt: roles, e metabolism, roles as components of, mb, hormones, fat-soluble vitamins, thermal insulators, signaling molecules. Fats as e reserves: tissue fuel stores for average 70 kg human: Simplified representation of a fatty acid: will have polar hear = carboxyl group, non-polar head = long carbon chain, saturated or unsaturated (2le bond) Saturated fatty acids: unsaturated fatty acids, do(cid:374)"t (cid:374)eed to (cid:373)e(cid:373)orize ta(cid:271)les, ex. Stearic acid = 18 c"s with no double bond: ex. Oleic acid = 13c"s with double bond at c9; cis/trans: cis/trans: Oleic acid in cis/trans configuration: cis = both h on same side and create bend in chain, trans = both h on opposite side of chain. Most fa are cis: when you get trans bond you need to convert it to cis as seen later. But in nature can have 3 diff.
