WebbSeveral cases of the effects of phosphorylation on protein–protein binding are reviewed in Table 1. Regulation of Binding by Disorder–Order and Order–Disorder Transitions Upon Phosphorylation Many proteins and protein regions are intrinsically disordered under native conditions, namely, they contain no or very little well-defined structure. Protein binding can influence the drug's biological half-life. The bound portion may act as a reservoir or depot from which the drug is slowly released as the unbound form. Since the unbound form is being metabolized and/or excreted from the body, the bound fraction will be released in order to maintain equilibrium. Visa mer Plasma protein binding refers to the degree to which medications attach to proteins within the blood. A drug's efficiency may be affected by the degree to which it binds. The less bound a drug is, the more efficiently it … Visa mer Only the unbound fraction of the drug undergoes metabolism in the liver and other tissues. As the drug dissociates from the protein, more and more drug undergoes metabolism. Changes in the levels of free drug change the volume of distribution because … Visa mer A drug in blood exists in two forms: bound and unbound. Depending on a specific drug's affinity for plasma proteins, a proportion of the drug may become bound to the proteins, with the remainder being unbound.
