Role of histidine in cataract formation in Atlantic salmon (Salmo salar L).

Abstract

Elevated levels of dietary histidine have been shown to reduce cataract formation in farmed Atlantic salmon. The aim of this study was to explore the possible roles of histidine and its derivatives in the lens. Since histidine is a buffer at physiological pH, its contribution to lens buffering capacity was examined. In addition, the role of histidine and its analogues in lens osmoregulation was investigated
