Document Summary

Methyl end + ch2 chain + acid (cooh) Unsaturated: has 1+ double bond(s) (kink, usually cis) Esterified fatty acid something attached to o from oh pka = 4. 8. [# c] : [# double bonds], e. g. 18:0 n-octadecanoic acid (n = normal, no branching) [# c] : [# double bonds] ( # of double bond from carboxylic acid end, # of other) cis-,cis-9, 12-octadecadienoic acid (di for two, ene for double bond) + if saturated, + if longer, - if kink (think packing) Triacylglycerols: 1 glycerol + 3 fatty acid chains. Dehydrated hydrophobic can be packed well. Found in adipose (fat) cells: oil droplet with shitloads of triacylglycerols. Structural lipids polar head group, non-polar tail all in membranes membrane lipids (1) phospholipids. Phosphatidylcholine (phosph -1, head +1 zwitterionic, no net neutral) Phosphatidylethanolamine (phosph -1, head +1 zwitterionic, net neutral) Diphosphotidylglycerol (cardiolipin) (phosph -1, head glycerol bound to two 2 sn-glycerol-3-phosphate) Phosphotidylinositol (phosph -1, inositol 6 c ring all oh)
