# Is sucrose made of 2 glucose molecules or 1 glucose and 1 fructose? [duplicate]

I have read from several sources about sucrose and some say it is 2 glucose molecules and some others say it is 1 glucose molecule and 1 fructose molecule.

I know that both of these are related disaccharides since they have the same molecular formula of $\ce{C12H22O11}$

So which one is actually sucrose and what is the other disaccharide.

• This was discussed recently here on Chemistry SE chemistry.stackexchange.com/questions/14562/… I checked a number of other links and all agree that sucrose is glucose + fructose – ron Aug 12 '14 at 14:39
• I don't think it is a duplicate because it is about the structure of 2 related sugars, not the melting point of sugars. – Caters Aug 12 '14 at 14:40
• Yes, but the link shows the structure of sucrose and identifies the two monosaccharides. – ron Aug 12 '14 at 14:41
• but several sources I have read said that sucrose is glucose + glucose. – Caters Aug 12 '14 at 14:42
• maltose is glucose+glucose – ron Aug 12 '14 at 14:44
