Glycine betaine aldehyde, often simply called betaine aldehyde, is an intermediate in the metabolism of glycine, serine and threonine. The human aldehyde dehydrogenase (EC 1.2.1.3) stimulates the transformation of betaine aldehyde to glycine betaine. Betaine aldehyde is a substrate for choline dehydrogenase (mitochondrial).
