Sucrose is made by the glosidic linkage between glucose and fructose whereas maltose is made by the glycosidic linkage between two glucose molecules.
the first figure is maltose and second is sucrose(courtesy Google images)
take solution of substance in one test tube; in another test tube take acetic acid, water and phenyl hydrazine in 1:2:1 ratio. mix the solution of both test tubes and heat at water bath.
if precipitates form immediately--> its glucose;
if precipitates form after long heating--> its lactose.
Seliwanoff test; it differentiates between ketose (sugars with a ketone group) like fructose and aldose sugars (sugars which end in carbonyl groups as far as I can remember) like galactose.
There is a wikipedia page with a diagram and information about the reagents.
Benedict's test - from a clear blue solution to a cloudy rust/brown solution.
Maltose will give a positive Benedict's Test (Orange colour) while, Sucrose will give a negative Benedict's Test (Aqua colour)
I believe that this distinction is not possible.
maltose do not react in iodine test
wla pud ko kblo. hahaha
all reducing sugars - monosaccharides like glucose and a few non-reducing disaccharides like maltose
Maltase is an enzyme that acts on the compound maltose. It is present in saliva and pancreatic juice and catalyzes maltose into glucose.
Disaccharides are a type of sugar that are formed when two monosaccharides bond together. e.g. sucrose (table sugar) is a disaccharide of glucose and fructose. Maltose is a disaccharide of two glucose molecules.
maltose and sucrose, both have the same molecular formula, C12H22O11. maltose is formed from two glucose units sucrose is formed from one glucose and one fructose units
Glucose

I have that they are both carbohydrates.
Glucose + Glucose = 2 Glucose units Maltose is a disaccharide
Hydrolysis is involved in maltose to glucose digestion. Maltose, a starch, gets hydrolyzed into a couple remains of glucose in this carbohydrate digestion.

is a disaccharide formed from two units of glucose. Maltose can be broken down into two glucose molecules by hydrolysis.what are some properties of maltose?Maltose is a malt sugar. The molecular formula for maltose is C12H22O11.
The composition of maltose is 2 glucose units. This is because glucose is the 'primary' composition in a monosaccharide and maltose is found in Disaccharide, which is the 'secondary' composition. ~Geek
maltose is formed between to alpha glucose molecules. The carbon 1 hydroxyl of one alpha glucose molecule is bonded with the carbon 4 hydroxyl group of another alpha glucose molecule thus creating the disachride maltose and in the process producing water
Two glucose, because maltose is two glucose join together
difference between cellulose and maltose is that cellulose is (chiefly in technical texts) while maltose is (carbohydrate) a disaccharide, c12h22o11 formed from the digestion of starch by amylase; is converted to glucose by maltase.
Glucose and Glucose
Both maltose aswell as lactose are disaccharides, where maltose is made up of two glucose units, whereas lactose is made up of 1 unit of glucose and 1 unit of galactose. Barfoed's test answers only for mono and disaccharides. Presence of red precipitate would indicate a positive result for monosaccharides. Thus doing Barfoed's test does not distinguish between maltose and galactose since both are disaccharides.
