Q

Amino Acid Conjugation
functional group/ substrates

A

carboxylic acids

25
Amino Acid Conjugation enzyme
N-acyltransferase
26
Amino Acid Conjugation co-enzyme
the drug acts like the co-enzyme
27
amino acid conjugation (where the the amino acid is the first step)
amino acid is the co-enzyme
28
enzyme of amino acid conjugation
HSCOA
29
methylation co-enzyme
SAM
30
methylation enzyme
methyltransferase
31
common substrates of methylation
phenols, catechols and amines
32
if methylation happens on the catechol what enzyme is used
COMT
33
if methylation happens on the amine what enzyme is used
N-methyl transferase
34
glutathione conjugation
drug binds to to the thiol on the GSH and a derivative can form. this derivative is not water soluble and cannot be excreted by the body
35
enzymes involved in mercaptopuric acid formation
γ-glutamyltranspeptidase – Cysteinylglycinase – N-acetylase
36
4 electrophiles that can take part of mercaptopuric acid formation
Micheal acceptor imidoquinone arene oxide epoxides
