According to IUPAC nomenclature it is called chromene . There are two isomers of benzopyran that vary by the orientation of the fusion of the two rings compared to the oxygen, resulting in 1 benzopyran chromene and 2 benzopyran isochromene the number denotes where the oxygen atom is located by standard naphthalene like nomenclature. The radical chemistry radical form of benzopyran is paramagnetic . The unpaired electron is delocalized over the whole benzopyran molecule, rendering it less reactive than one would expect otherwise, a similar example is the cyclopentadienyl radical. Commonly, benzopyran is encountered in the reduced state, where it is partially saturated with one hydrogen, introducing a tetrahedral CH sub 2 sub group in the pyran ring. There are thus many different structural isomers due to multiple possible positions of the oxygen atom and the tetrahedral carbon class wikitable Structural isomers of chromene center File 2H Chromen.svg 120px br 2 H chromene br 2 H 1 benzopyran center center File 4H Chromen.svg 120px br 4 H chromene br 4 H 1 benzopyran center center 5 H chromene center center 7 H chromene center center 8a H chromene center class wikitable Structural isomers of isochromene center File 1H Isochromen.svg 120px br 1 H isochromene br 1 H 2 benzopyran center center File 3H Isochromen.svg 120px br 3 H isochromene br 3 H 2 benzopyran center are 4a H or 6 H or 8 H isochro ... more details

Molybdopterins , when reacted with molybdenum or tungsten in the form of molybdate or tungstate, are a class of cofactor biochemistry cofactors found in most molybdenum Mo and all tungsten W enzymes. Synonyms for molydopterin are MPT and pyranopterin dithiolate. The nomenclature for this biomolecule can be confusing Molybdopterin per se contains no molybdenum rather, this is the name of the ligand that will eventually bind the active metal. After molydopterin is eventually complexed with molybdate, the complete ligand is usually called molybdenum cofactor . Molydopterin consists of a pyranopterin, a complex heterocycle featuring a pyran fused to a pterin ring. In addition, the pyran ring features two thiolate s, which serve as ligand s in molybdo and tungstoenzymes. In some cases, the alkyl phosphate group is replaced by an alkyl diphosphate nucleotide . Enzymes that contain the molybdopterin cofactor include xanthine oxidase , DMSO reductase , sulfite oxidase , and nitrate reductase . The only molybdenum containing enzymes that do not feature molydopterins are the nitrogenase s enzymes that fix nitrogen . These contain an iron sulfur center of a very different type, which also usually contains molybdenum. However, if molybdenum is present, it is directly bonded to other metal atoms. ref name gramene http pathway.gramene.org META NEW IMAGE?type COMPOUND&object CPD 4 Structure, synthesis, empirical formula for ... more details
