Pepsinogen
pepsinogen The inactive precursor of the enzyme pepsin. Pepsinogen is secreted by the lining of the vertebrate stomach into the lumen, where it is converted to pepsin by hydrochloric acid and also by the action of pepsin itself.... Read more |

proto-
proto-. Primitive, first, early, or precursor of something. Proto-Doric was an early primitive harbinger of the Doric Order, as in the rock-cut tombs at Beni-Hasan, Egypt (c.2133–1786 bc). Proto-Ionic refers to precursors of aspects of the Ionic Order, especially the Aeolic type of capital... Read more |

Renin
renin A proteolytic enzyme (see protease) that is involved in the formation of the hormone angiotensin, which raises blood pressure. Renin is secreted into the blood by juxtaglomerular cells (see juxtaglomerular apparatus) of the kidney under the control of the sympathetic nervous system; its... Read more |

Thyroglobulin
thyroglobulin (TGB) A glycoprotein, made in the thyroid gland, that consists of about 5000 amino acids, some of which are tyrosine residues. TGB is the precursor of the thyroid hormones, thyroxine and triiodothyronine. Iodine binds to the tyrosine residues in thyroglobulin, which is then hydrolysed... Read more |

Zymogens
zymogen Any inactive enzyme precursor that, following secretion, is chemically altered to the active form of the enzyme. For example, the protein-digesting enzyme trypsin is secreted by the pancreas as the zymogen trypsinogen. This is changed in the small intestine by the action of another enzyme,... Read more |

carboxypeptidase
carboxypeptidase Any enzyme that catalyses the hydrolysis of amino acid residues from the carboxyl terminus of a peptide or polypeptide (see exopeptidase). Pancreatic juice contains a carboxypeptidase that is secreted into the duodenum. The enzyme is secreted as an inactive precursor,... Read more |

photoheterotroph
photoheterotroph Any organism that uses energy derived from the sun to manufacture organic compounds from organic precursors in photosynthesis. For example, under certain conditions some purple sulphur bacteria use organic acids (rather than hydrogen sulphide) as a source of hydrogen. See... Read more |

procarcinogen
procarcinogen The precursor of an active carcinogen. The procarcinogen itself is not usually carcinogenic but is converted to the active carcinogen after it has been metabolized. For example, the drug diethylstilboestrol (a synthetic oestrogen no longer in clinical use) is metabolized to an epoxide... Read more |

Plasma cells
plasma cells Antibody-producing cells found in the epithelium of the lungs and gut and also in bone-forming tissue. They develop in the lymph nodes, spleen, and bone marrow when antigens stimulate lymphocytes to form the precursor cells that give rise to them (see B cell).... Read more |
