protein -
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"
meat the flesh of animals (including fishes and birds and snails) used as food
eggs,
egg animal reproductive body consisting of an ovum or embryo together with nutritive and protective envelopes; especially the thin-shelled reproductive body laid by e.g. female birds
milk produced by mammary glands of female mammals for feeding their young
legume the seedpod of a leguminous plant (such as peas or beans or lentils)
capsid the outer covering of protein surrounding the nucleic acid of a virus
gluten a protein substance that remains when starch is removed from cereal grains; gives cohesiveness to dough
amino acid,
aminoalkanoic acid organic compounds containing an amino group and a carboxylic acid group; "proteins are composed of various proportions of about 20 common amino acids"
enzyme any of several complex proteins that are produced by cells and act as catalysts in specific biochemical reactions
fibrin a white insoluble fibrous protein formed by the action of thrombin on fibrinogen when blood clots; it forms a network that traps red cells and platelets
filaggrin the main protein of the keratohyalin granules; "the specific target of the immune response in rheumatoid arthritis is filaggrin"
growth factor a protein that is involved in cell differentiation and growth
haptoglobin a protein in plasma that binds free hemoglobin and removes it (as from wounds)
prostate specific antigen,
psa a protein manufactured exclusively by the prostate gland; PSA is produced for the ejaculate where it liquifies the semen and allows sperm cells to swim freely; elevated levels of PSA in blood serum are associated with benign prostatic hyperplasia and prostate cancer
proteome the full complement of proteins produced by a particular genome
simple protein a protein that yields only amino acids when hydrolyzed
cytokine any of various protein molecules secreted by cells of the immune system that serve to regulate the immune system
ferritin a protein containing 20% iron that is found in the intestines and liver and spleen; it is one of the chief forms in which iron is stored in the body

protein -
Any of numerous large, complex naturally-produced molecules composed of one or more long chains of amino acids, in which the amino acid groups are held together by peptide bonds.
Wikipedia
Proteins (also known as polypeptides) are organic compounds made of amino acids arranged in a linear chain and folded into a globular form. The amino acids in a polymer are joined together by the peptide bonds between the carboxyl and amino groups of adjacent amino acid residues. The sequence of amino acids in a protein is defined by the sequence of a gene, which is encoded in the genetic code.

protein Any of a class of high-molecular weight polymer compounds composed of a variety of alfa-amino acids joined by peptide linkages.
