Lipid Metabolism Flashcards
What are triglycerides, and how are they used?
Fat storage molecules that can be broken down into fatty acids and glycerol to meet energy demands.
What are lipoproteins?
Molecules made of cholesterol, triglycerides, phospholipids, and proteins that transport triglycerides and cholesterol.
: How are lipids obtained and processed
Lipids are ingested in the diet, liberated from adipose tissue, and synthesized in the liver.
What happens to triglycerides from lipoproteins?
They are catabolized to glycerol and fatty acids via lipolysis
What happens to glycerol in fasted conditions
It is metabolized to generate ATP
: How are fatty acids processed in the liver?
They are metabolized to ketone bodies via beta-oxidation.
: What happens to glycerol and fatty acids in fed conditions?
: They are converted to triglycerides for storage.
Why are most lipids and fats insoluble?
: Due to their molecular structure, which makes them hydrophobic
