Thought for today: If someone calls you a “FAT HEAD”,

What is a Lipid?
Any substance that is insoluble in water but
soluble in organic solvents
Does this mean any water insoluble compound?
What are some examples I would recognize?
Stearic acid….a saturated fatty acid
Oleic acid…an unsaturated fatty acid
Bees wax….a fatty acid ester
Vitamins A,D,E,K…the fat-soluble vitamins
Lecithin…a membrane glycerophospholipid
Classifications (all lipids)

Esterified vs Non-esterified
Odd chain vs Even chain
