We, primates, lost the ability to make ascorbate. Therefore we are genetically deficient.

Several nucleotides can activate sugars. In the case of glucose for glycogen synthesis it is UTP. See next page. The first reaction a), is reversible but it is coupled to b) that releases -5 kcal/mol and favors reaction a).
