    "a diet high in protein"
    is a type of: macromolecule, supermolecule - any very large complex molecule; found only in plants and animals
    subtypes:
    • 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
    • recombinant protein - a protein derived from recombinant DNA
    • actomyosin - a protein complex in muscle fibers; composed of myosin and actin; shortens when stimulated and causes muscle contractions
    • aleurone - granular protein in outermost layer of endosperm of many seeds or cereal grains
    • amyloid - (pathology) a waxy translucent complex protein resembling starch that results from degeneration of tissue
    • apoenzyme - a protein that combines with a coenzyme to form an active enzyme
    • compound protein, conjugated protein - a protein complex combining amino acids with other substances
    • 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
    • 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)
    • iodinated protein, iodoprotein - a protein that contains iodine
    • nucleoprotein - any of several substances found in the nuclei of all living cells; consists of a protein bound to a nucleic acid
    • opsin - retinal protein formed by the action of light on rhodopsin
    • phosphoprotein - containing chemically bound phosphoric acid
    • plasma protein - any of the proteins in blood plasma
    • 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
    • antibody - any of a large variety of proteins normally present in the body or produced in response to an antigen which it neutralizes, thus producing an immune response
