Fatty Acid metabolism Flashcards
Location of FA synthesis
Cytosol of liver, mammary glands, adipose, and kidneys
Substrates needed to make palmitate (16 C)
8 acetyl coA (1/2 of the carbons) + 14 NADPH + 7 ATP
Step 1 substrate to get acetyl coA out of mitochondria
Citrate
Step 2 conversion of acetyl coA into malonyl CoA
Acetyl coA carboxylase and biotin cofactor
Step 2 conversion of acetyl coA into malonyl CoA
Acetyl coA carboxylase and biotin cofactor
Step 3 linking of malonyl coA units
Fatty acid synthase (reduce, dehydrate, reduce)
Purpose of carnitine shuttle
To get FA into the mitochondria for beta oxidation/ energy production
Carnitine shuttle starting products
Lysine, methionine, ATP
Carnitine shuttle location
Liver and kidneys
Backbone of sphingolipids
Ceramide
