WebJul 6, 2024 · Biotransformation sites are the: Liver (primary site, which also makes it the most susceptible to damage by ingested toxicants). Kidneys (about 10-30% of the liver's capacity). Skin, intestines, testes, and placenta (low capacity). WebBiotransformation is the biochemical modification of one chemical compound or a mixture of chemical compounds. Biotransformations can be conducted with whole cells, their lysates, or purified enzymes. [1] Increasingly, biotransformations are effected with purified enzymes. Major industries and life-saving technologies depend on biotransformations.
