Using complete sentences, explain why glucose and many other monosaccharides can be represented by both a cyclic form (as seen in Haworth projections) and an open-chain form (as seen in Fischer projections). NOTE: I am not asking you to explain what Haworth and Fischer projections are; I am asking why these monosaccharides can be represented using a cyclic form and a non-cyclic form.
