β-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 β-oxidation, α-oxidation, or ω -oxidation of fatty acids.
two carbon atoms are removed from the carboxyl end of a fatty acid
occurs in the endoplasmic reticulum
occurs when an alkyl group is present on the Beta carbon of a fatty acid
the alpha carbon atom is hydroxylated
results in a fatty acid with two carboxyl groups
in animals, occurs in mitochondria or peroxisomes
Homework Answers
Beta oxidation - Mitochondrial oxidation of fatty acids takes place by beta-oxidation. In the first stage-β oxidation-the fatty acids undergo oxidative removal of successive two-carbon units in the form of acetyl-CoA, starting from the carboxyl end of the fatty acyl chain.the bond between alpha- beta carbon is broken hence the name beta-oxidation is given.
Omega oxidation - the alcoholic group is subsequently oxidised to -COOH by dehydrogenase producing a fatty acid with a carboxyl group at each end.
