In organic chemistry, pyranose is a collective term for saccharides that have a chemical structure that includes a six-membered ring consisting of five carbon atoms and one oxygen atom (a heterocycle). There may be other carbons external to the ring. The name derives from its similarity to the oxygen … See more

What is the Difference Between Pyranose and Furanose
See more on pediaa.comPyranose is a saccharide having a six-membered ring with five carbon atoms and one oxygen atom. Hence pyranose molecules are cyclic in nature. The name “pyranose” comes from the word “pyran” due to the similarity in their ring structure. However, when compared to the structure of pyran, pyranose does not have dou…Pyranose - an overview | ScienceDirect Topics
