### substance | activator | enzyme:

Proteolytic enzyme
* All proteolytic enzymes are secreted as inactive zymogens to protect the gland from autodigestion.
* are used to liquefy dead tissue, which are later absorbed.
* can irritate the skin and mucous membranes.
* cause substantial breakdown of storage proteins.
* have many useful properties.

Several enzyme
* Most several enzymes break down clot proteins
  - substances
  - participate in synthesis
* can work together in a specific order, creating metabolic pathways.
* may have roles.

Similar enzyme
* are present in birds, mammals and fish.
* exist for other chlorinated pesticides.

Specific enzyme
* Some specific enzymes help proteins.
* Some specific enzymes involve in activations
  - carcinogen activations
  - glycolysis
* act like software to read, copy, and manipulate the code in predictable ways.
* break down starch into amino acids
  - simple sugar
* control each of the different reactions.
* remove specific types of damage.

Telomerase
* is an enzyme
* replenishes the telomeres on the ends of our linear chromosomes.

Thrombin
* acts by activating the clotting cascade, even in the presence of heparin.
* are proteins.
* catalyzes fibrin formation and results in consumption of fibrinogen.
* is an enzyme
* plays a wide range of roles in the regulation and maintenance of hemostasis.
* reacts with fibrinogen during the clotting process.
* stimulates blood coagulation, but is also a potent platelet agonist
  - the clotting pathway

Transferase
* are enzymes that transfer molecules.
* is an enzyme

### substance | activator | enzyme | transferase:

Transaminase
* are usually normal.
* catalyze the transfer of amino groups from amino acids to alpha-keto acids.

### substance | activator | enzyme:

Trypsin
* activates trypsinogen, chymotrypsinogen and procarboxypeptidase.
* breaks down protein in the duodenum.
* can activate a number of the other pancreatic zymogens.
* can, when activated, activate the other inactive enzymes.
* catalyzes the conversion of more trypsinogen to trypsin
  - the other zymogens
* cleaves on the C-terminal side of arginine and lysine
  - proteins at the carboxyl side of the basic amino acid residues arginine and lysine
* continues protein digestion in the small intestine.
* is an enzyme necessary in the digestion of protein
  - example of a widely-used protease currently derived from animal organs
* is an important digestive enzyme produced by the pancreas
  - that breaks peptide bonds in proteins
  - synthesized as an inactive precursor, trypsinogen
* then activates all other zymogens as well as trypsinogen
  - other zymogens by cleaving off polypeptide sequences
  - cleaves proteins to smaller polypeptides
* works in alkahne, neutral, or even acid media.

Urease
* catalyzes the hydrolysis of urea to form ammonia and carbamate.
* helps digest urea to produce ammonia and bicarbonate.

Active substance
* Most active substances contain impurities
  - toxic impurities
* form Asarum europaeum.
* work internally and externally to balance, detoxify, and refresh.

Addictive substance
* All addictive substances alter brain chemistry
  - do affect the brain systems that control motivation
  - start out as plants
* Some addictive substances find in tobacco.
* are good at inducing recursive loops
  - medicine
