Aspirin Absorption - Biology - ProfessorDr. Bongsup Cho - Lecture 16 of 20 - Video-lecture

Video-lecture, Biology

Description: "This simple animation illustrates how an acidic molecule like aspirin can change its polarity depending on the environment. Aspirin, which is non-ionized in the strongly acidic stomach environment (pH ~2), can be readily absorbed across the membrane. Once in the bloodstream (pH 7.4), however, the aspirin molecule is deprotonated to become ionic, polar, and thus water soluble and more able to travel to target sites. The deprotonation is indicated by the removal of a hydrogen atom (white sphere) when the aspirin molecule is taken into the bloodstream"
