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.

  • $\begingroup$ 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 $\endgroup$

  • $\begingroup$ I don't think it is a duplicate because it is about the structure of 2 related sugars, not the melting point of sugars. $\endgroup$

  • $\begingroup$ Yes, but the link shows the structure of sucrose and identifies the two monosaccharides. $\endgroup$

Sucrose is composed of one glucose and one fructose monosaccharide. Two glucose molecules form maltose.
