The pathway starts with a 3-phosphoglyceric acid interacting with an NAD driven D-3-phosphoglycerate dehydrogenase / α-ketoglutarate reductase resulting in an NADH, a hydrogen ion and a phosphohydroxypyruvic acid. This compound then interacts with an L-glutamic acid through a 3-phosphoserine aminotransferase / phosphohydroxythreonine aminotransferase resulting in a oxoglutaric acid and a DL-D-phosphoserine. The latter compound then interacts with a water molecule through a phosphoserine phosphatase resulting in a phosphate and an L-serine. The L-serine interacts with an acetyl-coa through a serine acetyltransferase resulting in a release of a Coenzyme A and a O-Acetylserine. The O-acetylserine then interacts with a hydrogen sulfide through a O-acetylserine sulfhydrylase A resulting in an acetic acid, a hydrogen ion and an L-cysteine
