alpha-ketoisocaproic acid & alpha-ketoisovaleric acid

[Endreos]

Hi there

 

I need some help with a "clinical detective story" on my med studies.

My task is:

 

alpha-ketoisocaproic acid: highly elevated

alpha-ketoisovaleric acid: highly elevated

 

Describe the chemical structure of these acids.

Are these acids common in our body?

If yes, how are they produced in our body?

If not, from what substances can our body alternatively create them?

 

I'm not really sure where to look. Found something about metabolism of leucine, but not too much. Can anyone help me out here, and give me a direction where to look for information and stuff?

Thanks

What two functional groups do these two compounds have in common with each other?

What did you find out about the metabolism of leucine?
