Immunochemical detection of oxalate monoalkylamide, an ascorbate-derived Maillard reaction product in the human lens.
Carbohydrates with reactive aldehyde and ketone groups can undergo Maillard reactions with proteins to form advanced glycation end products. Oxalate monoalkylamide was identified as one of the advanced glycation end products formed from the Maillard reaction of ascorbate with proteins. In these experiments, we have analyzed human lens proteins immunochemically for the presence of oxalate monoalkylamide. Oxalate monoalkylamide was absent in most of the very young lenses but was present in old and cataractous lenses. The highest levels were found in senile brunescent lenses. Incubation experiments using bovine lens proteins revealed that oxalate monoalkylamide could form from the ascorbate degradation products, 2,3-diketogulonate and L-threose. These data provide the first evidence for oxalate monoalkylamide in vivo and suggest that ascorbate degradation and its binding to proteins are enhanced during lens aging and cataract formation.

Morgagnian cataract.
It appears that morgagnian cataract is a special form of cortico-nuclear cataract. It is assumed that the process of fibre dissolution which is encountered in cortical cataract in general is speeded up and occurs en masse in morgagnian cataract. Enzymatic degradation of membrane and crystallin fibre components could then occur to produce liquefaction of the fibres and resorption of the cortical fluid. Factors responsible for the resistance of the nucleus to this process have been discussed. The high levels of calcium in the capsule and nucleus in this form of cataract could be due to the precipitation of calcium orthophosphate in the capsule and of calcium oxalate in the nucleus.
