Butyric acid (/ ˈ b j uː t ɪ r ɪ k /; from Ancient Greek: βούτῡρον, meaning "butter"), also known under the systematic name butanoic acid, is a straight-chain alkyl carboxylic acid with the chemical formula CH 3 CH 2 CH 2 COOH. It is an oily, colorless liquid with an unpleasant odor.
Carboxylic acids are organic acids characterized by a carboxyl (-COOH) functional group. The naming of these compounds is governed by IUPAC nomenclature, which ensures systematic and consistent naming of chemicals. Numerous organic compounds have other common names, often originating in historical source material thereof.
Combining the names of functional groups with the names of the parent alkanes generates what is termed a systematic nomenclature for naming organic compounds. In traditional nomenclature, the first carbon atom after the carbon that attaches to the functional group is called the alpha carbon ; the second, beta carbon, the third, gamma carbon, etc.
1-Propanol (also propan-1-ol, propanol, n-propyl alcohol) is a primary alcohol with the formula CH 3 CH 2 CH 2 OH and sometimes represented as PrOH or n-PrOH.It is a colourless liquid and an isomer of 2-propanol. 1-Propanol is used as a solvent in the pharmaceutical industry, mainly for resins and cellulose esters, and, sometimes, as a disinfecting agent.
The side chains are grouped like this: 12-butyl-4,8-diethyl. (But this is not necessarily the final grouping, as functional groups may be added in between to ensure all groups are listed alphabetically.) The secondary functional groups are: a hydroxy- at carbon 5, a chloro- at carbon 11, a methoxy- at carbon 15, and a bromo- at carbon 18.
Eventually, [these] thioesters could have served to usher in ATP through its ability to support the formation of bonds between phosphate groups. However, due to the high free energy change of thioester's hydrolysis and correspondingly their low equilibrium constants, it is unlikely that these compounds could have accumulated abiotically to any ...
In the IUPAC nomenclature of organic chemistry, the systematic names of acyl groups are derived exactly by replacing the -yl suffix of the corresponding hydrocarbyl group's systemic name (or the -oic acid suffix of the corresponding carboxylic acid's systemic name) with -oyl, as shown in the table below.
In chemistry, the alkoxy group is an alkyl group which is singularly bonded to oxygen; thus R−O. Denoted usually with apostrophe('). The range of alkoxy groups is vast, the simplest being methoxy (CH 3 O−). [1] An ethoxy group (CH 3 CH 2 O−) is found in the organic compound ethyl phenyl ether (C 6 H 5 OCH 2 CH 3, also known as ethoxybenzene).
