And so, depending on the pathway that is followed, that sulfur atom is released as either thiocyanate, hydrogen sulfide or sulfur trioxide, and we ultimately form the Pyruvate. Now let's move on to the conversion of Alanine into Pyruvate. Now, we actually discussed this before, so we saw that Alanine could be transformed to Pyruvate in a single step, in a single transamination step. And the enzyme that catalyzes this is known as Alanine aminotransferase. So this enzyme utilizes a co enzyme, PLP, so, paradoxyl phosphate. And so Alanine basically reacts with alpha keylutrate.
