Deficiency Of Biotin Vitamin B7. The antibiotics medicine kills the biotin producing bacteria in the intestine. So these medications can arise the deficiency of vitamin H. Let us define a carboxylation reaction as the addition of a CO2 unit to a substrate molecule, and decarboxylation as loss of CO2. Decarboxylation reaction reactions are typically quite thermodynamically favorable due to the entropic contribution of cleaving a single molecule into two, one of which is a gas. Conversely, we can expect carboxylation reactions to be energy-requiring, and we should not be surprised to learn ATP hydrolysis is coupled to carboxylation. T…
