Common Name | Acetaminophen cystein |

Description | Acetaminophen cystein, also known as paracetamol cysteine or aa-cysteine, belongs to the class of organic compounds known as l-cysteine-s-conjugates. L-cysteine-S-conjugates are compounds containing L-cysteine where the thio-group is conjugated. Acetaminophen cystein is a very strong basic compound (based on its pKa). Within humans, acetaminophen cystein participates in a number of enzymatic reactions. In particular, acetaminophen cystein can be biosynthesized from NAPQI and glutathione through its interaction with the enzymes glutathione S-transferase p and glutathione S-transferase theta-1. In addition, acetaminophen cystein can be converted into acetaminophen cystein through its interaction with the enzyme multidrug resistance-associated protein 1. In humans, acetaminophen cystein is involved in acetaminophen metabolism pathway. |
