Carbohydrates can generally be represented by the general formula C\(_x\)(H\(_2\)O)\(_y\), for fructose the value for "X" is

Carbohydrates follow the general formula \(\text{C}_x(\text{H}_2\text{O})_y\). To find the value of x for fructose, you need to know the molecular formula of fructose.

Fructose has the molecular formula C₆H₁₂O₆. Rewriting this in the carbohydrate general formula:

\[\text{C}_6\text{H}_{12}\text{O}_6 = \text{C}_6(\text{H}_2\text{O})_6\]

Comparing with \(\text{C}_x(\text{H}_2\text{O})_y\), the value of x = 6 (and y = 6 as well).

Fructose is a monosaccharide (simple sugar) that is an isomer of glucose. Both have the same molecular formula C₆H₁₂O₆, but they differ in structural arrangement: glucose is an aldose (contains an aldehyde group) while fructose is a ketose (contains a ketone group).
