What is the role of co-lipase in the action of pancreatic lipase?

Back

Co-lipase is a protein that is required for the effective action of pancreatic lipase, as it helps anchor the lipase to the lipid interface, facilitating the digestion of dietary fats.

Front

What is alpha oxidation?

Back

Alpha oxidation is a metabolic process that involves the oxidative removal of one carbon atom from the fatty acid chain, occurring primarily in peroxisomes.

Front

What is the primary product of alpha oxidation?

Back

The primary product of alpha oxidation is a fatty acid that is one carbon shorter than the original fatty acid.

Front

What is the significance of phytanoyl CoA alpha hydroxylase in alpha oxidation?

Back

Phytanoyl CoA alpha hydroxylase is an enzyme that is involved in the alpha oxidation of phytanic acid, but it is not required for all alpha oxidation processes.

Front

What is the difference between alpha oxidation and beta oxidation?

Back

Alpha oxidation removes one carbon atom from the fatty acid chain, while beta oxidation breaks down fatty acids into two-carbon units (acetyl-CoA) for energy production.

Front

What is the function of pancreatic lipase?

Back

Pancreatic lipase is an enzyme that breaks down dietary fats into free fatty acids and glycerol, aiding in fat digestion.

Front

What is the role of magnesium in enzymatic reactions?

Back

Magnesium acts as a cofactor for many enzymes, stabilizing negative charges and assisting in the proper functioning of the enzyme.

Front

What is the process of fatty acid oxidation?

Back

Fatty acid oxidation is the metabolic process by which fatty acids are broken down to produce energy, primarily through beta oxidation in the mitochondria.

Front

What are peroxisomes?

Back

Peroxisomes are organelles in cells that contain enzymes for various metabolic processes, including the oxidation of fatty acids and the detoxification of harmful substances.

Front

What is the energy yield of beta oxidation?

Back

Beta oxidation yields ATP through the production of acetyl-CoA, which enters the citric acid cycle, and NADH and FADH2, which enter the electron transport chain.
