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.’
‘Asian and African populations showed selection in genes affecting the metabolism of the plant sugars mannose and sucrose.’
‘These data suggest that galactose and mannose may compete with glucose for uptake, whereas sucrose and fructose do not.’
‘The mannose is dissolved in water and/or incorporated in a pharmaceutical agent or food for the purpose of administration.’
‘The outermost layer of the cell wall is composed of diverse proteins bearing polysaccharide side chains composed of mannose.’
Origin
Late 19th century: from mannite ‘mannitol’ + -ose.
