Lipids Flashcards
What is the way a FA is named in terms of A:B (C)
A No of carbons
B number of double bonds
C location of double bonds
What are TAGs
Esters of FA and glycerol,
Omega 3 is a nonessential fatty acid, what does this mean
Not produced in the body and have to be obtained from diet
What are the benifits of taking omega 3
Lowers plasma cholesterol, therefore decreasing risk of artherosleorsis, lowers TAG preventing obesity

In beta oxidation, Fa are activated . Where the do they head to
They have to go to the mitochondria matrix
What are the 4 stages of degradation
Dehydrogenation
Hydration
Dehydrogenation
Triolysis
Very long fatty acids require the formation of a structure before b oxidation. What is this structure called
Peroxisome
What does B oxidation produce and where does this occur
Keto bodies in the liver
What is the main keto bodie called
Beta hydroxybutyrate
What is the name of enzyme in the liver r3sponible for keto body production
hmg CoA synthase
Ketone bodies are produced where in the cell
Mitochondrial matrix
Ketone bodies are not soluble therefore require transport around the blood, true or false
False
In the formation of fatty acids, elongation occurs, what are the 4 steps
Condensation Reduction Dehydration Reduction Conducted 7 times to get palmityl CoA
