“…Cholinesterases (ChE), carboxylic ester hydrolases, are a family of enzymes that play an essential role in neural and motor functions (Alves et al, 2015;Wilson, 2010). These enzymes are responsible for the removal of the neurotransmitter acetylcholine (ACh) from the synaptic cleft by hydrolysis (Habig and DiGiulio, 1991).…”

“…Pseudocholinesterases have higher affinity for propionylthiocholine (PTCh) or butyrylthiocholine (BTCh), being sensitive to eserine and selectively inhibited by iso-OMPA, while relatively insensitive to BW284C51 (Eto 1974). The characterization of ChE is important because different ChE may respond differently to anticholinesterase agents such that the measurement of this enzyme activity in a given species using one substrate instead of the other can lead to misinterpretation of results in ecotoxicological studies (Alves 2015).…”

“…A atividade de Colinesterase muscular teve uma porcentagem de 73% de inibição após 16 horas de exposição a Masoten (Figura 6). A acetilcolinesterase em músculo é normalmente utilizada como um dos principais biomarcadores de exposição a organofosforados 44,45 . Entretanto, aqui chamaremos as colinesterases encontradas no músculo apenas de colinesterases, pois recentemente observou-se que, com a tilápia, a atividade colinesterásica realizada por diferentes substratos de cadeia alquídica de tamanho variável (acetiltiocolina, propioniltiocolina e butiriltiocolina) não evidenciou prevalência na reação de hidrólise a nenhum dos substratos testados em enzimas solubilizadas com NaCl e detergente não iônico 46 .…”
