Figure 1. Percentage in contribution of the selected B-esterases: (A) Acetylcholinesterase (AChE), (B) pNPA-Carboxylesterase (pNPA-CE), and (C) αNB-Carboxylesterase (αNB-CE) in several tissues of the two fish species: sea bass and hake. The contribution in each tissue is based on the hydrolysis rates using the three commercial substrates independently.
