还原糖 Reducing sugar

(重定向自Reducing substances)

还原糖是在碱性溶液中能生成醛基和羰基的糖。还原糖可被适当的氧化剂氧化成醛糖酸、糖二酸等。 还原糖包括如葡萄糖、果糖、甘油醛等的所有单糖,以及乳糖、麦芽糖等二糖,和寡糖。 蔗糖和海藻糖在溶液中不生成醛基和酮基,故不属于还原糖。

Reducing sugar 还原糖

(重定向自Reducing substances)
Reducing form of glucose (the aldehyde group is on the far right)
Equilibrium between cyclic and open-chain form in one ring of maltose
Offenkettige Form der Glucose mit Aldehydgruppe (oben)

A reducing sugar is any sugar that is capable of acting as a reducing agent because it has a free aldehyde group or a free ketone group. All monosaccharides are reducing sugars, along with some disaccharides, oligosaccharides, and polysaccharides. The monosaccharides can be divided into two groups: the aldoses, which have an aldehyde group, and the ketoses, which have a ketone group. Ketoses must first tautomerize to aldoses before they can act as reducing sugars. The common dietary monosaccharides galactose, glucose and fructose are all reducing sugars.
