Toxin
A toxin is a naturally occurring organic poison produced by metabolic activities of living cells or organisms. Toxins occur especially as a protein or conjugated protein. The term toxin was first used by organic chemist Ludwig Brieger (1849–1919) and is derived from the word toxic. Toxins can be small molecules, peptides, or proteins that are capable of causing disease on contact with or absorption by body tissues interacting with biological macromolecules such as enzymes or cellular receptors. Toxins vary greatly in their toxicity, ranging from usually minor (such as a bee sting) to potentially fatal even at extremely low doses (such as botulinum toxin). Toxins are largely secondary metabolites, which are organic compounds that are not directly involved in an organism's growth, development, or reproduction, instead often aiding it in matters of defense. Terminology Toxins are often distinguished from other chemical agents strictly based on their biological origin. Le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toxicant
A toxicant is any toxic substance, whether man-made or naturally occurring. By contrast, a toxin is a poison produced naturally by an organism (e.g. plant, animal, insect). The different types of toxicants can be found in the air, soil, water, or food. Occurrence Toxicants can be found in the air, soil, water, or food. Humans can be exposed to environmental toxicants. Fish can contain environmental toxicants. Cigarette smoke contains toxicants. E-cigarette aerosol also contains toxicants. The emissions of a heat-not-burn tobacco product contains toxicants. Most heavy metals are toxicants. Diesel exhaust contains toxicants. Pesticides, benzene, and asbestos-like fibers such as carbon nanotubes are toxicants. Possible developmental toxicants include phthalates, phenols, sunscreens, pesticides, halogenated flame retardants, perfluoroalkyl coatings, nanoparticles, e-cigarettes, and dietary polyphenols. Related terms By contrast, a toxin is a poison produced naturally by an or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Toxin (comics)
Toxin is a fictional character appearing in American comic books published by Marvel Comics. He has been depicted as a superhero and at times a supervillain. The character is the offspring of Carnage, the third major symbiote in the Marvel Universe, the ninth known to have appeared in the comics outside of the Planet of the Symbiotes storyline, and the first symbiote that Spider-Man considers an ally, despite several temporary alliances with Venom in the past. The Toxin symbiote's various hosts are former NYPD police officer Patrick Mulligan, Eddie Brock, and teenager Bren Waters. Stephen Graham portrayed Detective Mulligan in the Sony's Spider-Man Universe film '' Venom: Let There Be Carnage''. Fictional character biography Carnage produced an offspring: a third symbiote. Carnage felt only dislike and hatred towards this new spawn, even before giving "birth" to it, both fearing that it could become much stronger, and being generally disgusted at the thought of giving birth. ...

Toxification
Toxication, toxification or toxicity exaltation is the conversion of a chemical compound into a more toxic form in living organisms or in substrates such as soil or water. The conversion can be caused by enzymatic metabolism in the organisms, as well as by abiotic chemical reactions. While the parent drug are usually less active, both the parent drug and its metabolite can be chemically active and cause toxicity, leading to mutagenesis, teratogenesis, and carcinogenesis. Different classes of enzymes, such as P450-monooxygenases, epoxide hydrolase, or acetyltransferases can catalyze the process in the cell, mostly in the liver. Parent non-toxic chemicals are generally referred to as ''protoxins''. While toxication is generally undesirable, in certain cases it is required for the ''in vivo'' conversion of a prodrug to a metabolite with desired pharmacological or toxicological activity. Codeine is an example of a prodrug, metabolized in the body to the active compounds morphine and co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
