| Which cells never use B Oxidation |
RBCs and Brain Cells |
| Where does B oxidation occur |
Mitochondria |
| B oxidation utilizes which kind of metabolism |
aerobic |
| Uncommon Fatty Acids |
Long chains with odd numbers of carbons |
| Common Fatty Acids |
Long Chain (even numbers) and mono- or polyunsaturated FA |
| Medium Fatty Acid chains |
6-12 C |
| Short Fatty Acid Chains |
4 carbons |
| Very Long Acid Chains |
more than 20 carbons |
| Triacylglycerol Lipolysis |
Tracylglycerol -> Diacylglycerol -> Monoacylglycerol -> Glycerol |
| Long chain fatty acid cross the plasma membrane via |
facilitated transport and diffusion |
| Fatty acids transported on what protein in plasma |
albumin |
| How is ATP expended in the cytosol during B Oxidation |
Fatty acids bound to acyl CoA molecules |
| Carnitine |
transports Fatty Acyl into mitochondria |
| What binds to FA as soon as it enters the mitochondria |
binds to another CoA |
| When does B Oxidation occur |
in a fast |
| What mitochondria do not perform B oxidation |
mitochondria in brain cells |
| major regulation of B oxidation |
Adipose (hormone sensitive) Lipase |
| B oxidation Starting materials |
Long Chain FA
NAD+
FAD |
| B oxidation products |
Acetyl CoA
NADH
FADH2 |
| How far are fatty acids cleaved during B oxidation |
until there are only Acetyl CoA Molecules |
| How many FADH2 and NADH produced in B oxidation |
1 per each B oxidation |
| Propionyl- CoA |
3 carbons |
| When is propionyl CoA Produced |
when Fatty acid chains have odd numbers |
| Where does Propionyl CoA enter the Kreb Cycle |
production of Succinyl CoA |
| FADH2 production from B oxidation of unsaturated fatty acids |
1 less FADH2 per double bond |
| When are medium chain fatty acids B-oxidized |
as soon as they are absorbed from the gut |
| w-oxidation produces |
dicarboxylic acids |
| Where does w-oxidation occur |
opposite end of fatty acid chain that B oxidation occurs |
| Peroxisomal Oxidation |
oxidizes long, branched chains into fatty acyl-CoA that is then B oxidized |
| Peroxisomal and W-fatty acid oxidation regulation |
only by the supply of fatty acids they oxidize |
