Chem- Fats Flashcards
What are the products produced by triglyeride digestion
Monoacylglyerol
2 Fatty acids
What happens once fat is absorbed by eneterocytes
some transported to liver while others are re esterfoed and combined w protein to form lipoproteins
Where are chylomicrons (lipoprotein) absorbed
Absorbed by central lacteals in villi of sm intestine and are transported via thoracic duct
What are the saturated fatty acids`
Palmitic acid
Stearic acid
arachidic acid
What are examples of unsaturated FA
Omega 3/6
What are the non essential FA and what are they made of
Arachidonic acid
–made from linoleum acid
Where does the breakdown of fatty acids occur
Mito of adipocytes and its purpose is to produce acetyl CoA (which enters krebs)
what drives the FA into the mito matrix
Carnatine
Once inside the mitochondria what happens to acyetl coa
beta oxidation
what inhibits beta oxidation
high lvls of citrate
What is excreted in the breath and causes a fruity smell during diabeic ketoacidosis
Acetone
What happens in lipogenesis
Excess glucose in diet first converted to glycogen , then glucose is converted to acetyl coA then to maloney CoA which turns into fatty acids
What is the rate limiting enzyme of lipogenesis
acetyl coa carboxylase
(which converts acetyl coa to maloney coA)
What is the rate limiting set in steroid production and where is it produced
Gonads and adrenal glands
HMG coA reductase (which converts HMG CoA to mevalonate)
