What's the difference between carbohydrate and sugar?

Carbohydrate


Definition:

  • (n.) One of a group of compounds including the sugars, starches, and gums, which contain six (or some multiple of six) carbon atoms, united with a variable number of hydrogen and oxygen atoms, but with the two latter always in proportion as to form water; as dextrose, C6H12O6.

Sugar


Definition:

  • (n.) A sweet white (or brownish yellow) crystalline substance, of a sandy or granular consistency, obtained by crystallizing the evaporated juice of certain plants, as the sugar cane, sorghum, beet root, sugar maple, etc. It is used for seasoning and preserving many kinds of food and drink.
