Lipid Metabolism

Flashcards covering key terms and concepts related to lipid metabolism, digestion, and absorption.

Triacylglycerol (TAG)

A predominant dietary lipid that contains three long-chain fatty acids.

Lipolysis

The process of breaking down stored fat into fatty acids and glycerol.

Hormone Sensitive Lipase

An enzyme that regulates the lipolysis process in adipose tissue.

Cholecystokinin (CCK)

A hormone that stimulates the release of bile and pancreatic juice.

Micelles

Tiny micro droplets that emulsify dietary lipids, aiding in absorption.

Apolipoprotein B-48 (apoB-48)

The major apoprotein associated with chylomicrons essential for their formation.

Lipoprotein Lipase (LPL)

An enzyme that digests the triacylglycerols of chylomicrons and VLDL in the blood.

Carnitine Shuttle

A transport system that facilitates the entry of long-chain fatty acids into the mitochondria for oxidation.

Beta-Oxidation

The metabolic pathway that breaks down fatty acids into acetyl-CoA.

Acetyl-CoA Carboxylase

The rate-limiting enzyme for fatty acid synthesis, converting acetyl-CoA into malonyl-CoA.
