Carbamates are a group of organic compounds sharing a common functional group with the general structure -NH(CO)O-. More precisely the carbamate group is considered an amide group with an alkoxy or hydroxy functional group next to the carbonyl group. The parent compound of all carbamates is called carbamic acid or NH₂COOH. An organic compound is any member of a large class of chemical compounds whose molecules contain carbon, with the exception of carbides, carbonates, carbon oxides and gases containing carbon. ... In ecology functional groups are collections of organisms based on morphological, physiological, behavioral, biochemical, or environmental responses or on trophic criteria. ... In chemistry, the term amide has several meanings. ... In chemistry, the alkoxyl group is an alkyl group linked to oxygen thus: R-O- In this function, R represents the alkyl group. ... This prefix in chemical nomenclature indicates the presence of a hydroxyl functional group (-OH). ... In organic chemistry, a carbonyl group is a functional group composed of a carbon atom double-bonded to an oxygen atom. ...

Carbamates in Biochemistry

The carbamate functional group is formed when a carbon dioxide molecule reacts with the amino terminus of a peptide chain or an amino group of an amino acid, adding a COO⁻ group to it and releasing a cation (H⁺ ion). In ecology functional groups are collections of organisms based on morphological, physiological, behavioral, biochemical, or environmental responses or on trophic criteria. ... Carbon dioxide is an atmospheric gas comprised of one carbon and two oxygen atoms. ... In chemistry, an amino acid is any molecule that contains both amino and carboxylic acid functional groups. ...

"R" stands for the atoms attached to the other end of the nitrogen molecule of the amino group. Note that the COO⁻ group is a resonance structure, so the single bonds both show a degree of double bond character, and the charge is delocalised over the two oxygen atoms. This reaction is reversible (with reaction constant K << 1 in the above reaction), as the N-C bond is highly labile. Image File history File links Carbamates. ... This article does not cite its references or sources. ... In chemistry, delocalized electrons are electrons in a molecule that do not belong to a single atom or a covalent bond. ... A reversible reaction is a chemical reaction that may be reversed. ...

Some Occurrences of Carbamate Groups in Nature

In haemoglobin, carbamate groups are formed when carbon dioxide molecules bond with the amino termini of the globin chains. This helps to stabilise the protein when it becomes deoxyhaemoglobin and increases the likelihood of the release of remaining oxygen molecules bound to the protein. 3-dimensional structure of hemoglobin Hemoglobin or haemoglobin is the iron-containing oxygen-transport metalloprotein in the red cells of the blood in mammals and other animals. ...

Ribulose 1,5-bisphosphate carboxylase/oxygenase (the enzyme required to fix a carbon dioxide molecule at the start of the Calvin Cycle) also requires the formation of a carbamate to function. At the active site of the enzyme, a Mg²⁺ ion is bound to a glutamate residue, an aspartate residue and a lysine carbamate, which hold the ion in place. The carbamate is formed when an uncharged lysine side chain near the ion reacts with a carbon dioxide molecule from the air (not the substrate carbon dioxide molecule), which then renders it charged, and so therefore able to bind the Mg²⁺ ion. Ribulose-1,5-bisphosphate carboxylase/oxygenase, most commonly known by the shorter name RuBisCO, is an enzyme (EC 4. ... It has been suggested that this article or section be merged with Light-independent reaction. ... Glutamic acid (Glu) or glutamate (the anionic form) is one of the 20 standard amino acids used by all organisms in their proteins. ... Aspartic acid, also known as aspartate, the name of its anion, is one of the 20 natural proteinogenic amino acids which are the building blocks of proteins. ... Lysine is one of the 20 amino acids normally found in proteins. ...

A group of insecticides also contain the carbamate functional group for example Carbofuran, Furadan, Carbaryl, Sevin and 2-(1-Methylpropyl)phenyl methylcarbamate. An insecticide is a pesticide whose purpose is to kill or to prevent the multiplication of insects. ... Carbofuran is the most toxic of the carbamate pesticides. ... Carbofuran is the most toxic of the carbamate pesticides. ... Carbaryl is a chemical in the carbamate family used chiefly as an insecticide. ... Carbaryl is a chemical in the carbamate family used chiefly as an insecticide. ... 2-(1-methylpropyl)phenol methylcarbamate, CAS number 3766-81-2, is a carbamate insecticide. ...
