The definition of carbohydrates is simple. Figuring out which ones to eat for weight loss is complex. But here you get answers to both!

From Dr. Dave's Biochemistry textbook from college.
Biochemistry, Third Edition, 1988 by Lubert Stryer, Stanford University

"One of the four major classes of biomolecules." They are carbohydrates, proteins, nucleic acids, and lipids (fats)."



"Carbohydrates are aldehyde or ketone compounds with multiple hydroxyl groups."


"First, carbohydrates serves as energy stores, fuels, and metabolic intermediates."
"Second, ribose and deoxyribose sugars form part of the structural framework of DNA and RNA."
"Third, polysaccharides are structural elements in the cell walls of bacteria and plants, and in the exoskeletons of arthropods."
"Fourth, carbohydrates are linked to many proteins and lipids."



"Monosaccharides, the simplest carbohydrates, are aldehydes or ketones that have two or more hydroxyl groups . . ."



"Disaccharides consist of two sugars joined by on O-glycosidic bond." They include sucrose (table sugar), lactose (milk), and maltose.


From the New World Dictionary of the American Language, Second College Edition:

"Carbohydrate - any of certain organic compounds, including the sugars, starches, and celluloses, which have the general formula Cx(HxO)y; carbohydrates form an important class of foods in animal nutrition, supplying energy to the body"
