the calculated transport kinetics also suggest that the beta-hb molecule has a greater affinity for the transport ( mediator ) protein during starvation , although the maximal rate of uptake by brain due to a carrier processes mediated vmax is decreased either because there is a smaller quantity of the mediating molecule or because there is trans inhibition by a high cellular concentration of beta-hb or some analog .
