What are carbohydrates? What do they look like?
A carbohydrate is a biological molecule consisting of carbon, hydrogen and oxygen atoms. A carbohydrate is the most common type of an organic compound. It is built of small, repeating units that form bonds with each other to form a larger molecule. In the carbohydrates, the small units are called monosaccharides. Carbs have different forms glucose, fructose, and sucrose.
What does it do for your body?
It is a common source of energy in living organisms. Carbohydrates can provide energy, store energy, build macromolecules, and spare protein and fat for other uses.
How is it used?
It is used in the body by providing energy for working muscles, providing fuel for the central nervous system, enabling fat metabolism, and preventing protein from being used as energy.
Where does it come from? Where is it found in the body?
It comes into the body externally in food that is digested into small pieces—either glucose or a sugar that is easily converted to glucose—that can be absorbed through the small intestine's walls. It is found in liver and muscles in the body.
Who discovered carbs?
The molecule was discovered by Claude Bernard. According to the American Chemical society, "In the 19th century, the great French physiologist, Claude Bernard, discovered glycogen, the starch-like substance found in muscles and the liver."
