Bisphenol A sulfonation is impaired in metabolic and liver disease [PDF]

open access: yes, 2016
Background: Bisphenol A (BPA) is a widely used industrial chemical and suspected endocrine disruptor to which humans are ubiquitously exposed. The liver metabolizes and facilitates BPA excretion through glucuronidation and sulfonation.
