A molecule composed mainly of carbon, hydrogen, and oxygen in about a 1:2:1 ratio is most characteristic of which class of biomolecules?

Carbohydrates are built with carbon, hydrogen, and oxygen in about a 1:2:1 ratio, reflecting the common empirical formula CH2O and the general composition Cn(H2O)n. This hydrated pattern is seen in simple sugars like glucose (C6H12O6) and underpins the idea that carbohydrates store and provide quick energy as well as serve as structural components. Lipids differ because they are rich in carbon and hydrogen with relatively little oxygen and do not follow the CH2O ratio. Proteins and nucleic acids include other elements (like nitrogen and phosphorus) and do not fit this simple 1:2:1 proportion. Therefore, the described molecule best characterizes carbohydrates.
