Definitions of protein

  1. any of a large group of nitrogenous organic compounds that are essential constituents of living cells; consist of polymers of amino acids; essential in the diet of animals for growth and for repair of tissues; can be obtained from meat and eggs and milk and legumes; " a diet high in protein"
  2. In chemical analysis, the total nitrogenous material in vegetable or animal substances, obtained by multiplying the total nitrogen found by a factor, usually 6. 25, assuming most proteids to contain approximately 16 per cent of nitrogen.
  3. A body now known as alkali albumin, but originally considered to be the basis of all albuminous substances, whence its name.
  4. An essential or necessary element in food; the muscle- making quality of food; proteid.
  5. One of a group of substances constituting the greater part of animal and vegetable tissues; they are formed chiefly by plants. They are of very complex constitution, all containing carbon, hydrogen, nitrogen, and oxygen, and some containing in addition iron, phosphorus, or sulphur; chemically they are regarded as peptides ( polypeptides) or combinations of aminoacids and their derivatives. They are colorless, odorless, in general tasteless, and of varying degrees of solubility; they are putrefiable and readily undergo chemical change, hydrolysis, under the influence of ferments and on boiling with dilute acids or alkalies.
