NADPH-dependent reduction of glyceraldehyde: a unusually high activity in the lens of the camel (Camelus dromedarius).
The enzymes of the polyol pathway, namely aldose reductase and sorbitol dehydrogenase, were measured in camel lens extracts. A NADPH-dependent glyceraldehyde and erythrose reductase activity 25 times higher than that of calf lens was observed in camel lens. A preliminary comparison between this enzyme activity present in the camel and aldose reductase of calf lens is reported.
