Overview of Protein Biochemistry Flashcards
1
Q
ketogenic AA
A
generate acetyl co a when broken down
produce ATP through TCA cycle or ketone synthesis
2
Q
2 examples of post-translationally modified AAs
A
- hydroxy proline & hydroxy lysine: structural components of colagen, need vitamin c
- gamma carboxygluamate: prothrombin uses to target membranes
- Ornithine: part of Urea cycle
3
Q
Protein breakdown in GI tract vs in cells
A
GI Tract: Peptidases
Cells: Ubquination (targets to proteasome) & Degradation (lysosomes)
4
Q
Aromatic AA
A
tryptophan, phenylalanine, tyrosine
5
Q
glucogenic AA
A
methionine, valine, histadine
6
Q
Ketogenic AA
A
leucine, lysine
7
Q
both glycogenic and ketogenic AA
A
isoleucine, phenylalanine, typtophan, tyrosine
8
Q
Glutamine
A
accepts nitrogen from peripheral tissues
