Ec number what is

The third figure gives further information on the group eliminated e. CO2 in EC 4. These enzymes catalyse geometric or structural changes within one molecule.

According to the type of isomerism, they may be called racemases, epimerases, cis-trans-isomerases, isomerases, tautomerases, mutases or cycloisomerases. The subclasses are formed according to the type of isomerism, the sub-subclasses to the type of substrates. Ligases are enzymes catalysing the joining together of two molecules coupled with the hydrolysis of a diphosphate bond in ATP or a similar triphosphate.

In a few cases in Group 6, where the reaction is more complex or there is a common name for the product, a synthase name is used e. The second figure in the code number indicates the bond formed: EC 6. Sub-subclasses are only in use in the C-N ligases.

In a few cases it is necessary to use the word other in the description of subclasses and sub-subclasses. Register Login. Our site requires Javascript to run.

Newer sheets must contain a numeric identifier, however, this will may or may not be an EC number; the regulation is horridly complex; see the Section 1.

The current regulation covering packaging and labelling in the European Union is the Classification, Labelling and Packaging CLP Regulation which was enacted in and took full effect in This law requires the use of a a unique digit formula identifier UFI on product packaging effective in By , the UFI will become mandatory on the label of all products classified for health or physical hazards. Fields that may contain a special character semicolon, newline, or double quote , are enclosed in double quotes.

XML is a markup language for documents containing structured information. This format can de used by common database engines. The XML file provides the full list of Pre-registered substances. It contains for each substance its EC number, CAS number when available , name, synonyms when available , related substances and registration date.
