TRIACYLGLYCEROLS
Sources of fats
consumed in diet
stored in cells
synthesized in one organ for export to another
Mobiliztion of triacylycerols
in diet
in adipose tissue
Conversion of glycerol to glycolysis intermediate
ACTIVATION OF FATTY ACIDS
General process
FATTY ACID ACTIVATED
Fatty acid
based on Acyl- CoA Synthetase
Fatty acid + ATP+ CoA <-> Acyl- CoA+ PPi + AMP
Fatty Acyl- CoA
Transported by Carnitine System

FATTY ACID OXIDATION
have 3 stages
STAGE 2
Acetyl CoA oxidized to CO2 via the TCA cycle
Acetyl CoA are formed
oxidation in the mitochondrial
conversion in the cytosol

STAGE 3
Respiration and provide energy
STAGE 1
OXIDATION
Beta- oxidation of saturated fatty acid
1 cycle of B-oxidation remove 2 acetyl CoA, 2 pairs of electron and 4 H
3 more items...
OXidation of unsaturated fatty acid
Requires the enzyme enoyl- CoA to produce 6 acetyl CoA
Oxidation of odd number fatty acids
The products of the last pass through Beta- oxidation acetyl- CoA and propionyl- CoA
