pro·tein
(prō′tēn′, -tē-ĭn)n.
Any of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of one or more chains of amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.
[French protéine, from Late Greek prōteios, of the first quality, from Greek prōtos, first; see per in Indo-European roots.]
pro′tein·a′ceous (prōt′n-ā′shəs, prō′tē-nā′-), pro·tein′ic (prō-tē′nĭk), pro·tein′ous (prō-tē′nəs) adj.

protein
(ˈprəʊtiːn)n
(Biochemistry) any of a large group of nitrogenous compounds of high molecular weight that are essential constituents of all living organisms. They consist of one or more chains of amino acids linked by peptide bonds and are folded into a specific three-dimensional shape maintained by further chemical bonding

pro•tein
(ˈproʊ tin, -ti ɪn)n.
1. any of numerous organic molecules constituting a large portion of the mass of every life form, composed of 20 or more amino acids linked in one or more long chains, the final shape and other properties of each protein being determined by the side chains of the amino acids and their chemical attachments.
2. plant or animal tissue rich in such molecules, considered as a food source.

pro·tein
(prō′tēn′) One of a large class of complex organic chemical compounds that are essential for life. Proteins play a central role in biological processes and form the basis of living tissues. They consist of long, looping or folding chains of smaller compounds called amino acids. Enzymes, antibodies, and hemoglobin are examples of proteins.
