Structure:

Dextrose, also known as glucose, has a molecular structure consisting of six carbon atoms, twelve hydrogen atoms, and six oxygen atoms. It is an aldohexose, meaning it contains an aldehyde functional group (-CHO) and six carbon atoms arranged in a straight chain. The carbon atoms are numbered from 1 to 6, with the aldehyde group located at carbon 1. The structure of dextrose is often depicted in a Fischer projection, with the hydroxyl groups (-OH) extending above and below the carbon chain.
