BICH 410 Lipid Metabolism

Flashcards summarizing key vocabulary terms and definitions related to lipid metabolism, including digestion, absorption, and transport processes.

Lipid Metabolism

The process of digestion, absorption, and transport of lipids.

Triacylglycerols

A type of lipid that makes up about 90% of dietary fats.

Micelles

Structures formed by the emulsification of fats aided by bile salts.

Pancreatic lipase

An enzyme that breaks down triacylglycerols in the small intestine.

Chylomicrons

Lipoprotein particles that transport dietary lipids from the intestines to other locations in the body.

Emulsification

The process of breaking down fat globules into smaller droplets to aid digestion.

Apolipoproteins

Protein components of lipoproteins that facilitate lipid transport.

VLDL

Very Low Density Lipoprotein, a type of lipoprotein that transports triacylglycerols and cholesterol from the liver to tissues.

LDL

Low Density Lipoprotein, primarily responsible for delivering cholesterol to cells.

HDL

High Density Lipoprotein, involved in the transport of cholesterol away from the arteries.

I-FABP

Intestinal fatty acid-binding protein, which helps transport fatty acids within intestinal cells.

Colipase

A protein that enhances the activity of pancreatic lipase at the lipid-water interface.

Bile salts

Amphiphilic molecules synthesized from cholesterol that aid in lipid digestion and absorption.

Dietary lipids processing steps

The sequence of events from emulsification of fats by bile salts to the formation of chylomicrons.

Apoprotein A-I (ApoA-I)

An apolipoprotein that facilitates reverse cholesterol transport.

ApoB-100

A large apolipoprotein that is critical for the function of LDL.

ApoE

An apolipoprotein associated with chylomicrons and linked to Alzheimer's disease risk.
