Any of the class of simple sugars whose molecules contain six carbon atoms, such as glucose and fructose. They generally have the chemical formula C₆H₁₂O₆
- ‘For example, fruit pulp of many species contains the disaccharide sucrose and the hexoses, glucose and fructose.’
- ‘They have six atoms of carbon in each molecule and are therefore called hexoses.’
- ‘Like fructose, it is a six-carbon atom sugar, or a hexose.’
- ‘These hexoses were taken up and sucrose was synthesized and exported into the hypocotyl.’
- ‘The most important monosaccharides are hexoses such as glucose and galactose.’
Late 19th century: from hexa- six + -ose.
