2.8&2.9 Protein Digestion/Absorption Flashcards
What are Glucogenic Amino Acids degraded to? (2)
Pyruvate OR CAC precursors
What are Ketogenic Amino Acids degraded to? (2)
Acetyl CoA OR AcetoAcetate
Is an essential AA made in our body?
NO, we need to eat them. Our body makes NONessential AAs
What are the two Ketogenic AAs?
LEU-CINE & LY-SINE
What is the “conditional essential” AA?
Tyrosine
What are the 9 (10) Essential AAs?
PVT TIM HALL Histidine, Methionine, Thereonine, Valine, Isoleucine, Phenylalanine, Tryptophan, Leucine, Lysine (Tyrosine)
Which ion is used to symport Di and Tri Peptides from the lumen into the enterocyte?
H+
Which ion is used to symport MonoPeptides from the lumen into the enterocyte?
Na+
What digestive protein enzyme converts trypsinogen to trypsin?
EnteroPepidase (Picture of Pavlov for some reason)
What is the scientific term for Pro-Enzymes? Because you can’t just have protein breakers hanging out all the time!
Zymogens!
What does chymotrypsinogen get cleaved to in its active form?
alpha- chymotrypsin
Which enzyme breaks down hydrophobic AAs only?
Elastase
Which enzyme breaks down Aromatic AAs?
Chymotripsin
What sequences can mark a protein for death?
PEST (Proline, Glutamate??E?, Serine, Threonine)
What is the N terminal rule?
If there is a specific AA at the N terminal of a protein, it can determine how long it will live!
