Coordination chemistry

Upon deprotonation, the corrinoid ring is capable of binding cobalt. In vitamin B12, the resulting complex also features a benzimidazole-derived ligand, and the sixth site on the octahedron serves as the catalytic center.

The corrin ring resembles the porphyrin ring, which occurs in hemoglobin. Both feature four pyrrole-like subunits organized into a ring with a largely conjugated structure of alternating double and single bonds. In contrast to porphyrins, corrins lack one of the carbon groups that link the pyrrole-like units into a fully conjugated structure. With a conjugated system that extends only 3/4 of the way around the ring, and does not include any of the outer edge carbons, corrins have a number of non-conjugated sp3 carbons, making them more flexible than porphyrins and not as flat. A third closely related biological structure, the chlorin ring system found in chlorophyll, is intermediate between porphyrin and corrin, having 20 carbons like the porphyrins and a conjugated structure extending all the way around the central atom, but with only 6 of the 8 edge carbons participating.

Corroles (octadehydrocorrins) are fully aromatic derivatives of corrins.

Brian Corrin

Brian Mark Corrin (born July 4, 1945 in Winnipeg, Manitoba) was a politician in Manitoba, Canada. He was a member of the Legislative Assembly of Manitoba from 1977 to 1986, sitting as a New Democrat.The son of Max Corrin and Celia Nick, Corrin was educated at the University of Manitoba (B.A. 1967, LL.B, 1970) and subsequently practiced as a lawyer with the City of Winnipeg Solicitor's Office and then in private practise. From 1974 to 1977, he served as a New Democratic member of the Winnipeg City Council. During that period he also chaired the provincial Child Welfare Treatment Panel. In 1974, Corrin married Joy Margaret Kathleen Cooper. He later married Lorraine Monaster.He was first elected to the Manitoba legislature in the provincial election of 1977, defeating Tory candidate Geoff Dixon by over 1,000 votes in the north-end Winnipeg riding of Wellington. The Tories under Sterling Lyon won a majority government in this election, and Corrin sat with the opposition for the next four years as shadow Justice Minister.

When the NDP caucus met in 1979 to choose an interim leader following the resignation of Edward Schreyer, Corrin refused to cast a ballot and criticized the selection process. These actions may have ruined his chances for advancement within the party.

Corrin was easily re-elected in the redistributed riding of Ellice in the provincial election of 1981, as the NDP won a majority government under Howard Pawley. He did not receive a position in cabinet being appointed to be Legislative Assistant to the Ministers of Urban Affairs and Justice instead. In 1982 he was also appointed Legislative Assistant to the Premier.In 1983, while still serving in the legislature, Corrin challenged incumbent Bill Norrie for election as mayor of Winnipeg. He was defeated, due primarily to public opposition to the Pawley government's plans to re-entrench French language services in provincial law. He was also named Queens Counsel that year. He did not seek re-election to the legislature in 1986. In 1985 he was appointed chair of the provincial task force studying the impact of government regulations on business and continued in that role until 1987.In 1988, he was named a provincial judge. In 1996, he was found guilty of misconduct by a panel of six judges and suspended for 30 days. In February 2011, Corrin was charged with assault and uttering threats against a family member. He was cleared of the charge in November 2011.

Corrinoid

Corrinoids are a group of compounds based on the skeleton of corrin, a cyclic system containing four pyrrole rings similar to porphyrins. These include compounds based on octadehydrocorrin, which has the trivial name corrole.The cobalamins (vitamin B12) are the best known members of the group. Other prominent examples include cobyrinic acid and its hexaamide cobyric acid; cobinic acid and its hexaamide cobinamide; cobamic acid and cobamide.

Compounds containing the "Cob-" prefix (not corrin) are cobalt derivatives, and may include an oxidation state, as in "Cob(II)alamin". When cobalt is replaced by another metal or hydrogen, the name changes accordingly, as in ferrobamic acid or hydrogenobamic acid.

Dune (franchise)

Dune is a science fiction media franchise that originated with the 1965 novel Dune by Frank Herbert. Dune is frequently cited as the best-selling science fiction novel in history. It won the 1966 Hugo Award and the inaugural Nebula Award for Best Novel, and was later adapted into a 1984 film and a 2000 television miniseries. Herbert wrote five sequels, and the first two were presented as a miniseries in 2003. The Dune universe has also inspired some traditional games and a series of video games. Since 2009, the names of planets from the Dune novels have been adopted for the real-world nomenclature of plains and other features on Saturn's moon Titan.Frank Herbert died in 1986. Beginning in 1999, his son Brian Herbert and science fiction author Kevin J. Anderson published a number of prequel novels, as well as two which complete the original Dune series (Hunters of Dune in 2006 and Sandworms of Dune in 2007), partially based on Frank Herbert's notes discovered a decade after his death.The political, scientific, and social fictional setting of Herbert's novels and derivative works is known as the Dune universe, or Duniverse. Set tens of thousands of years in the future, the saga chronicles a civilization which has banned artificial intelligence but has also developed advanced technology and mental and physical abilities. Vital to this empire is the harsh desert planet Arrakis, only known source of the spice melange, the most valuable substance in the universe.

Due to the similarities between some of Herbert's terms and ideas and actual words and concepts in the Arabic language—as well as the series' "Islamic undertones" and themes—a Middle Eastern influence on Herbert's works has been noted repeatedly.

House Corrino

For the novel of the same name, see Dune: House Corrino.

Imperial House Corrino is a fictional noble family from the Dune universe created by Frank Herbert. The Corrinos come to power after humanity's victory against the thinking machines at the Battle of Corrin (from which they take their name), and rule until deposed by Paul Atreides approximately 10,000 years later during the events of the novel Dune (1965).

Hydra Head Records

Hydra Head Records is an independent record label that specializes in extreme metal music, founded in New Mexico by Aaron Turner (the frontman of Isis) in 1993. It has another imprint, Hydra Head Noise Industries, which specializes in experimental and noise music.

Hydra Head was founded in 1993 as a distribution company while Turner was still in high school. In 1995, he moved to Boston to attend art school. In late 1995, he was handed a demo by local band Vent. That seven-inch single would be the first record released on Hydra Head. The label grew to accommodate local bands such as Roswell, Corrin, Piebald, and Converge, and after Turner graduated from college in 1999, it became a full-time endeavor. In 2011, Hydra Head relocated to Los Angeles, California, from its former home in Boston, Massachusetts.Some of the bands signed to the label include Cave In, Xasthur, Kayo Dot, Boris, and Jesu. Its discography includes Botch, Khanate, and Harkonen, who were all signed to Hydra Head prior to their respective disbandings.

On September 11, 2012, Turner announced the "imminent demise of Hydra Head Records", stating that Hydra Head would take its first steps into shutdown "this December, at which point we are cutting off new releases from the label." The label would continue to stay operational, maintaining its back catalogue to pay off its "rather sizeable debts." The label's final release of new material was Worship is the Cleansing of the Imagination, a split album between JK Flesh & Prurient.

In 2017, Hydra Head released Oxbow's Thin Black Duke, a long-germinating album that was slated to come out on Hydra Head and had been unable to find another label since Hydra Head's closure. Discussing the album, Turner appeared open to releasing more albums "on a case-by-case basis"
