Lactose is classed as a "reducing sugar" as it contains a aldehyde group (-CHO) which is oxidised into (-COOH) when reacted with an oxidant such as Fehling's or Benedict's reagant (alkaline conditions).
A redox reaction (also known as an electron transfer reaction) occurs when the reagent is added to the reducing sugar (at 80°C) and the following reaction occurs:
2Cu(OH)2 + R-CH=O → Cu2O + R-COOH + 2H2O
as you can see, the 2Cu(OH)2 becomes Cu2O and is hence reduced from Cu2+ to Cu+, making the sugar it has reacted with a 'reducing sugar' :)

∙ 9y agoYes it is. It's not visible at first sight because the structure of the molecule doesn't show an aldehyde. There's an intermolecular reaction which releases an aldehyde, so the disaccharide becomes reducing.

What are the examples of disaccharide?
sucrose (common sugar), lactose, lactulose, trehalose, maltose, and cellobiose are common disaccharides.
Which sugar is NOT a reducing sugar?
Sucrose
Is gentiobiose reducing or non-reducing sugar?
yes it is a reducing sugar, it has a free anomeric OH group. thus it can also mutarotate
What is the action of strong alkali on reducing sugar?
The action of strong alkali on reducing sugar, reverses the form of sugar back and forth.
How hydrochloric acid affect non-reducing sugar?
A non-reducing sugar can be hydrolyzed using dilute hydrochloric acid. After hydrolysis and neutralization of the acid, the product is a reducing sugar. So acidic hydrolysis can convert the non-reducing sugars (disaccharides and polysaccharides) into reducing simple sugars.
Does lactulose raise your blood sugar?
no
How many Grams of sugar are in 10Grams of Lactulose?
15
Is lactulose ok for diabetica?
It is safe, because it is an indigestible sugar.
Do you give a diabetic lactulose?
Yes, but does lactulose cause diabetes blood sugar increase?
Is sucrose is reducing sugar?
No, it is not a reducing sugar.
Is maltose non reducing sugar?
maltose is a reducing sugar ..
Is beet root reducing sugar or non reducing sugar?
reducing sugar
How many Grams of sugar are in 15ml of lactulose?
1.2 mg
Is Cellobiose is reducing or non reducing sugar?
It's a reducing sugar.
Is there a sugar free lactulose product?
No, lactulose is itself a sugar. However, how it works is that it is not absorbed by the body but instead broken down to acids, which act to hold water in the stools to soften them and make them easier to pass, thereby alleviating constipation.
Is gentiobiose a reducing or non-reducing sugar?
a reducung sugar since it has an aldehyde group
What is reduced sugar?
A reducing sugar that, in a solution has an aldehyde or a ketone group. This allows the sugar has an reducing agent.
