Glucose falls under aldoses group of monosaccharides which are one of the carbohydrates.
Step-by-step explanation:
Generally, a molecule formed by combination of carbon, hydrogen and oxygen are termed as carbohydrates. The smallest of the saccharides are mono and disaccharides. The saccharides can contain an aldehyde or a ketone group in their structural formula.
The molecular formula of glucose is C6H12O6. It falls under monosaccharide as the molecular formula of monosaccharides are (CH2nO)n where the n will be 3,5 or 6. So the molecular formula of glucose exactly matches with the molecular formula of monosaccharide family.
Also, it is known that glucose contains an aldehyde so it can be termed as aldose for being a carbohydrate in monosaccharide family containing aldehyde group.
