Glyoxylic acid monohydrate 是一种既是醛又是羧酸的有机化合物。它是乙醛酸循环的中间体，使某些生物体能够将脂肪酸转化为碳水化合物。2,2-Dihydroxyacetic acid 被发现与原发性高草酸尿有关，这是一种先天性代谢错误。作为一种醛，乙醛酸酯也具有高活性，可以修饰蛋白质形成晚期糖基化产物(AGEs)。 Glyoxylic acid monohydrate is an organic compound that is both an aldehyde and a carboxylic acid. It 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).
