What's the difference between maltose and sugar?

Maltose


Definition:

  • (n.) A crystalline sugar formed from starch by the action of distance of malt, and the amylolytic ferment of saliva and pancreatic juice. It resembles dextrose, but rotates the plane of polarized light further to the right and possesses a lower cupric oxide reducing power.

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. Ordinary sugar is essentially sucrose. See the Note below.
  • (n.) By extension, anything resembling sugar in taste or appearance; as, sugar of lead (lead acetate), a poisonous white crystalline substance having a sweet taste.
  • (n.) Compliment or flattery used to disguise or render acceptable something obnoxious; honeyed or soothing words.

  • (v. t.) To impregnate, season, cover, or sprinkle with sugar; to mix sugar with.
  • (v. t.) To cover with soft words; to disguise by flattery; to compliment; to sweeten; as, to sugar reproof.

Example Sentences:
