Aldose Reductase

Function

Aldose Reductase (AldR) is an NADPH-dependent enzyme which reduces aldehydes and carbonyls. It reduces glucose to sorbitol in the glucose metabolism pathway.^[1]

Disease

The AldR is implicated in diabetics and causing Iodine Deficiency Disorder (IDD) and its treatment involves the use of IDD inhibitors of AldR.
