E-Z notation

Index E-Z notation

E-Z configuration, or the E-Z convention, is the IUPAC preferred method of describing the absolute stereochemistry of double bonds in organic chemistry. [1]

Absolute configuration

An absolute configuration refers to the spatial arrangement of the atoms of a chiral molecular entity (or group) and its stereochemical description e.g. R or S, referring to Rectus, or Sinister, respectively.

Alitretinoin

Alitretinoin, or 9-cis-retinoic acid, is a form of vitamin A. It is also used in medicine as an antineoplastic (anti-cancer) agent developed by Ligand Pharmaceuticals.

Bracket

A bracket is a tall punctuation mark typically used in matched pairs within text, to set apart or interject other text.

Cahn–Ingold–Prelog priority rules

The Cahn–Ingold–Prelog (CIP) sequence rules, named for organic chemists Robert Sidney Cahn, Christopher Kelk Ingold, and Vladimir Prelog — alternatively termed the CIP priority rules, system, or conventions — are a standard process used in organic chemistry to completely and unequivocally name a stereoisomer of a molecule.

Cis–trans isomerism

Cis–trans isomerism, also known as geometric isomerism or configurational isomerism, is a term used in organic chemistry.

Double bond

A double bond in chemistry is a chemical bond between two chemical elements involving four bonding electrons instead of the usual two.

Hyphen

The hyphen (‐) is a punctuation mark used to join words and to separate syllables of a single word.

International Union of Pure and Applied Chemistry

The International Union of Pure and Applied Chemistry (IUPAC) is an international federation of National Adhering Organizations that represents chemists in individual countries.

Italic type

In typography, italic type is a cursive font based on a stylized form of calligraphic handwriting.

IUPAC nomenclature of chemistry

The International Union of Pure and Applied Chemistry (IUPAC) has published four sets of rules to standardize chemical nomenclature.

Letter case

Letter case (or just case) is the distinction between the letters that are in larger upper case (also uppercase, capital letters, capitals, caps, large letters, or more formally majuscule) and smaller lower case (also lowercase, small letters, or more formally minuscule) in the written representation of certain languages.

Molecular geometry

Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule.

Organic chemistry

Organic chemistry is a chemistry subdiscipline involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms.

Small caps

In typography, small capitals (usually abbreviated small caps) are lowercase characters typeset with glyphs that resemble uppercase letters ("capitals") but reduced in height and weight, close to the surrounding lowercase (small) letters or text figures, for example:.

Stereochemistry

Stereochemistry, a subdiscipline of chemistry, involves the study of the relative spatial arrangement of atoms that form the structure of molecules and their manipulation.

Substituent

In organic chemistry and biochemistry, a substituent is an atom or group of atoms which replaces one or more hydrogen atoms on the parent chain of a hydrocarbon, becoming a moiety of the resultant new molecule.
