In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula CH 3 (whereas normal methane has the formula CH 4). In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds. It is a very stable group in ...
A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −C n H 2n−1. [2] Typically an alkyl is a part of a larger molecule. In structural formulae, the symbol R is used to designate a generic (unspecified) alkyl group. The smallest alkyl group is methyl, with the formula −CH 3 ...
In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition.
General chemical structure of a paraben (a para-hydroxybenzoate) where R = an alkyl group. Parabens are chemicals that are commonly used as preservatives in cosmetic and pharmaceutical products. Chemically, they are a series of parahydroxybenzoates or esters of parahydroxybenzoic acid (also known as 4-hydroxybenzoic acid). Research is being ...
In other less formal contexts, an alcohol is often called with the name of the corresponding alkyl group followed by the word "alcohol", e.g., methyl alcohol, ethyl alcohol. Propyl alcohol may be n-propyl alcohol or isopropyl alcohol, depending on whether the hydroxyl group is bonded to the end or middle carbon on the straight propane chain. As ...
They are formed by adding the suffix "-yl" to the hydrocarbon prefix. For example, a methyl group (CH3) is an alkyl group derived from methane (CH4). Halo prefixes: These prefixes are used to indicate the presence of a halogen atom (F, Cl, Br, or I) in a molecule. Some examples include: fluoro- (F) chloro- (Cl) bromo- (Br) iodo- (I) Suffixes [3]
1-Methylimidazole or N-methylimidazole is an aromatic heterocyclic organic compound with the formula CH 3 C 3 H 3 N 2.It is a colourless liquid that is used as a specialty solvent, a base, and as a precursor to some ionic liquids.
This protein is not a true enzyme since it removes the alkyl group from the lesion in a stoichiometric reaction and the active enzyme is not regenerated after it is alkylated (referred to as a suicide enzyme). The methyl-acceptor residue in the protein is a cysteine. [8]
