What is the reaction that bonds two monosaccharides called , what bond it creates and other products formed.
It is called condensation reaction, a glycosidic bond is formed and for each bond a H2= molecule is given off
Explain the difference between (a) and (b) glucose.
The OH ion in the C1 atom in a (a) Glucose molecule is pointed downwards, which is the opposite orientation of the OH ion in a (b) Glucose molecule.
What is the general formula for monosaccharides?
Cn(H20)n
