What Is a Carbohydrate?
CLASS NOTES from Science Prof Online
You may recognize carbohydrates as source of energy (starch, glycogen), but they fulfill a wide range of roles, including the structural materials of plants (cellulose in plant cell walls) and of some animals (chitin of an insect’s exoskeleton). Carbohydrates can also be components of other molecules such as interactive animated lesson from Wisc-Online.com.

Organic molecules are large chemical compounds that contain carbon-hydrogen bonds and are found in living things. The major classes of organic molecules are carbohydrates, proteins,
The term carbohydrate is actually a descriptor of what these molecules are composed of. They are “carbon hydrates,” in a ratio of one carbon molecule to one water molecule (CH2O)n.
