GO:0015761:   mannose transmembrane transport
The process in which mannose is transported across a lipid bilayer, from one side of a membrane to the other. Mannose is the aldohexose manno-hexose, the C-2 epimer of glucose. The D-(+)-form is widely distributed in mannans and hemicelluloses and is of major importance in the core oligosaccharide of N-linked oligosaccharides of glycoproteins.
