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' :)
Yes, dextrose is a reducing sugar.
Yes, maltose is a reducing sugar.
sucrose (common sugar), lactose, lactulose, trehalose, maltose, and cellobiose are common disaccharides.
Yes, a hemiacetal is a type of sugar that can act as a reducing sugar.
Sucrose is not a reducing sugar because it does not have a free aldehyde or ketone group that can participate in the reduction reaction.

It is safe, because it is an indigestible sugar.
Honey, giving lactulose to a diabetic is like giving a fish a bicycle - it just doesn't make sense. Lactulose is a type of sugar that can mess with blood sugar levels, which is the last thing a diabetic needs. Stick to the doctor's orders and keep that lactulose away from anyone with diabetes.

Oh, dude, lactulose is a sugar that doesn't get absorbed by the body, so it doesn't directly raise blood sugar levels. It just hangs out in your gut, doing its thing to help with constipation. So, like, you can enjoy your lactulose without worrying about a sugar rush.
No, it is not a reducing sugar.
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.
maltose is a reducing sugar ..
reducing sugar
Yes, lactulose solution is considered vegan as it is a synthetic non-digestible sugar made by reacting galactose with fructose. It does not contain any animal-derived ingredients.
lactose is a milk sugar, thus made from cow's milk
Yes, dextrose is a reducing sugar.
