释义	mannose /ˈmanəʊz / /ˈmanəʊs/ noun [mass noun] Chemistry A sugar of the hexose class which occurs as a component of many natural polysaccharides. Chemical formula: C6H12O6. Other sugars found in foods, such as sucrose (table sugar), fructose (fruit sugar) and mannose are converted to glucose almost as quickly as starch is.... These data suggest that galactose and mannose may compete with glucose for uptake, whereas sucrose and fructose do not.
