acetylator

acetylator

 [ah-set″ĭ-la´ter]
an organism capable of metabolic acetylation. Individuals that differ in their inherited ability to metabolize certain drugs, e.g., isoniazid, are termed fast or slow acetylators.

acetylator

/acet·y·la·tor/ (ah-set´ĭ-la″ter) an organism capable of metabolic acetylation; in humans, acetylator status (fast or slow) is determined by the rate of acetylation of sulfamethazine.

acetylator

an organism capable of metabolic acetylation. Those animals that differ in their inherited ability to metabolize certain drugs, e.g. isoniazid, are termed fast or slow acetylators.
