Lipids
Week W3
Lipids
Lipids are non-polar
this is why they dont mix with water
hydrophobic composed of C,H and O
Functions include:
energy storage
building membranes and other cell structures
chemical signalling: hormones
insulation
fats have 2.25x the energy carbohydrates have per gram
4 Major Families
glycerides
fats in food
phospholipids
membranes
steroids
tren, cholesterol, estrogen
waxes
bees
Glycerides
Lipids 1
, Glycerol
3 carbons, 3 OH
Saturated - MAXIMUM NUMBER OF HYDROGENS
Unsaturated - MISSING SOME HYDROGENS, AT LEAST ONE DOUBLE
BOND (POLY - MULTIPLE DOUBLE BONDS)
triglyceride
Ester linkages are formed between the fatty acids and the hydroxyls of the
glycerol in condensation reactions
Monoglycerides have 1 fatty acid
diglycerides have 2 fatty acids
triglycerides have 3 fatty acids
Lipids 2
