De novo synthesis of serine from the glycolytic intermediate 3-phosphoglycerate (3-PG) occurs through a pathway consisting of three sequential steps: phosphoglycerate dehydrogenase (PHGDH) oxidizes 3-PG to 3-phosphohydroxypyruvate (pPYR) using an NAD + cofactor, phosphoserine aminotransferase (PSAT) transaminates pPYR to phosphoserine (pSER) using glutamate as the nitrogen donor, and finally phosphoserine phosphatase (PSPH) dephosphorylates pSER to produce serine [68]

Understanding Bioavailability and Delivery One of the biggest challenges with glutathione is how well it is actually absorbed
