2,2-Dihydroxyacetic acid

2,2-Dihydroxyacetic acid (Formylformic acid) is an intermediate in the glyoxalate cycle, which enables certain organisms to convert fatty acids to carbohydrates.2,2-Dihydroxyacetic acid has been found to be associated with primary hyperoxaluria, an inborn error of metabolism. As an aldehyde, glyoxalate is also highly active and can modify proteins to form advanced glycosylation products (AGEs).
