The possibility of endogenous digoxin synthesis by actinide based primitive organism like archaea with a mevalonate pathway and cholesterol catabolism was considered [5-8].
Threonine catabolism takes place in the liver, mainly through two major pathways (Bird and Nunn, 1983) based on the enzymes threonine dehydratase (TDH, EC 4.2.1.16) and threonine dehydrogenase (TDG, EC 1.1.1.103).

"Whether the explanation is tissue redistribution, insufficient vitamin C provision in a setting of increased catabolism, or both, a consequence of in-hospital hypovitaminosis C could be cerebral hypovitaminosis C with a resulting mood disorder that could be easily ameliorated or prevented by adequate vitamin C provision," they conclude.
A good rule of thumb is, improve hydration, provide calories with high dextrose fluids, promote anabolism, and prevent catabolism. This prevents severe complications such as hypoglycemic seizures, severe acidosis, and even death.
