The skeletal formula of the antidepressant drug escitalopram, featuring skeletal representations of heteroatoms, a triple bond, phenyl groups and stereochemistry. The skeletal formula, line-angle formula, bond-line formula or shorthand formula of an organic compound is a type of molecular structural formula that serves as a shorthand representation of a molecule's bonding and some details of ...
Major secosteroid subclasses are defined by the steroid carbon atoms where this scission has taken place. For instance, the prototypical secosteroid cholecalciferol, vitamin D 3 (shown), is in the 9,10-secosteroid subclass and derives from the cleavage of carbon atoms C-9 and C-10 of the steroid B-ring; 5,6-secosteroids and 13,14-steroids are ...
The B-ring of the parent steroid is broken between C9 and C10 to yield D vitamins. A secosteroid (/ ˈ s ɛ k oʊ ˌ s t ɛ r ɔɪ d /) is a type of steroid with a "broken" ring. The word secosteroid derives from the Latin verb secare meaning "to cut", [2]: 241 and 'steroid'. Secosteroids are described as a subclass of steroids under the IUPAC ...
28 O, whose molecule is derived from that of gonane by replacement of a hydrogen atom on C3 position by a hydroxyl group. It is therefore an alcohol of gonane. More generally, any compounds that contain the gonane structure, additional functional groups , and/or modified ring systems derived from gonane are called steroids .
Russia said Friday it had arrested suspected members of a Colombian cartel trying to smuggle tens of millions of dollars worth of cocaine into Europe.. The suspects were caught loading 570 ...
Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are possibly arranged in the real three-dimensional space.
Social Security is the U.S. government's biggest program; as of June 30, 2024, about 67.9 million people, or one in five Americans, collected Social Security benefits. This year, we're seeing a...
