Mechanism of glucose epimerization into mannose by a) carbon shift and b) two successive hydride shifts. Selected aldohexoses (d-glucose, d-mannose, and d-galactose) and aldopentoses (d-xylose, l-arabinose, and d-ribose) are readily available components of biopolymers. Where does D-mannose occur naturally? A simple sugar, d-mannose is found naturally in high amounts inRead More →
