Question

B-Oxidation is the major pathway for fatty acid oxidation in mammals. However, other fatty acid oxidation pathways exist. Sort the following phrases based on whether they describe p-oxidation, a-oxidation, or w-oxidation of fatty acids -Oxidation a-Oxidation w-Oxidation the B carbon is oxidized occurs in the endoplasmic reticulum results in a fatty acid with two carboxyl groups occurs when an alk group is present on the carbon of a fatty acid in animal cells two carbon atoms are removed from the carboxyl end of a fatty acid takes place in peroxisomes but not mitochondria

Explanation / Answer

Beta oxidation

- the beta is oxidized.

- two carbon atoms are removed from the carboxyl end of a fatty acid.

Alpha oxidation

-Occurs when an alkyl group is present on the beta carbon of a fatty acid.

- in animals cells, takes place in peroxisomes, but not mitochondria.

Omega oxidation

- Occurs in the endoplasmic reticulum.

- results in a fatty acid with two carboxyl groups.
