Descripción

Aplicación

D-Mannitol is used as an osmolyte and transport facilitator in a variety of biological in vivo and in vitro applications, such as improvement of blood-brain barrier transport and hyperosmolar therapy. D-Mannitol is used as a substrate to identify, differentiate and characterized enzymes such as mannitol dehydrogenase(s). D-Mannitol is used in identify mannitol metabolizing bacteria.

Acciones bioquímicas o fisiológicas

A sugar alcohol sweet tastant. Used in sweetness inhibition studies.

Otras notas
