Serine, Glycine Biosynthesis

The video tutorial explains the biosynthesis of serine, glycine, and cysteine from the glycolysis intermediate 3-phosphoglycerate. It details the enzymatic steps involved in converting 3-phosphoglycerate to serine and then to glycine, highlighting the role of methylene tetrahydrofolate in nucleotide and SAM synthesis. The tutorial also discusses the energy dynamics of these pathways, noting the unusual generation of NADH due to the high energy of 3-phosphoglycerate.
