The instant a needle penetrates the rubber stopper, three things happen: air enters the vial headspace, the sterile barrier is permanently breached, and the multi-dose use clock starts
This is well illustrated by the velocity equation for the CBS reaction, the first step in the transsulfuration pathway: The first factor is simply Michaelis-Menten kinetics for the CBS reaction that uses homocysteine (Hcy) and serine (Ser) as substrates
This injection is especially helpful when the body cannot absorb vitamins efficiently through oral supplements
