And we form this high energy intermediate molecule, amino acrylate. And then the amino Acrylate basically undergoes a hydrolysis step or said another way, a diamondination step, in which we have the water molecule kicking off this ammonium group. And so we form this Pyruvate as a result. And so, again, the enzyme that catalyzes step is serene dehydrates. Now, glycine can actually be transformed into pyruvate by first transforming the glycine into serene. And the way that we form the serine from glycine is by adding a hydroxy methyl group.
