The amine definition describes a substituent molecule whose primary constituent atom is nitrogen. The amine meaning in organic chemistry defines a functional group that is best described as a derivative of ammonia, which is an inorganic molecule with the chemical formula {eq}NH_3 {/eq}. Theamine...
Amines are classified intoprimary,secondary,tertiary, and quaternary based on the number of alkyl groups attached to nitrogen. Primary amines are named by adding the suffix "amine" to thealkyl group, while secondary and tertiary amines require notation forsubstituentsdirectly off nitrogen, denoted as...
the nucleophilic nitrogen belonging to the amine attacks the carbonyl carbon. the carbon-oxygen double bond is broken and a new carbon-nitrogen sigma bond is formed. now a proton is transferred from the amine to the oxygen atom. in the next step of this nucleophilic addition reaction, the oh...
detonate by ignition from some source such as flame, spark, impact, or other means that will produceheatof sufficient magnitude. Secondary explosives require adetonatorand, in some cases, a supplementary booster. A few explosives can be both primary and secondary depending on the conditions of ...
Examples include the prolinecatalyzed addition of unmodified ketones to in situ generated or preformed imines, the acyclic amino acid and linear chiral primary amine-catalyzed Mannich-type transformations, the use of unmodified aldehydes as nucleophiles, the cross-Mannich transformation with unmodified ...
Methylamine is a usual aliphatic primary amine, in which the NH2is connected to a carbon chain. All aliphatic primary amines, including this one, are stronger bases than ammonia. As you can see in the formula, the major difference between ammonia and methylamine is the presence of the CH3grou...
PRRP has a role in both purine and pyrimidine synthesis; it is also involved in NAD and NADP formation and salvage pathways. PRRP though becomes committed particularly to purine biosynthesis when PRRP is converted into5-phosphoribosyl amineby having the pyrophosphate of PRRP replaced by the amide...
The primary structure of a protein is the specific number and order of amino acids that make up the protein chain, called a polypeptide, a simple protein molecule. The individual amino acids are linked together with a peptide bond between the carboxyl group of one amino acid and the amine gr...
The nucleobases adenine (A), cytosine (C), guanine (G), thymine (T), and uracil (U) are referred to asprimaryorcanonical. They are the fundamental nucleobases of the genetic code. DNA specifically has A, C, G, and T whereas RNA has A, C, G, and U. Thus, one of the ways to...
