Noun
the radical -NH2
Source: WordNetAn α-amino acid has a central carbon (the α or alpha carbon ) which is covalently bonded to a carboxyl group (thus they are carboxylic acids ), an amino group, a hydrogen atom and a variable group. Source: Internet
However, additional molecular interactions may render the amide form less stable; the amino group is expelled instead, resulting in an ester (Ser/Thr) or thioester (Cys) bond in place of the peptide bond. Source: Internet
A one-carbon unit from folic acid coenzyme N 10 -formyl-THF is then added to the amino group of the substituted glycine followed by the closure of the imidazole ring. Source: Internet
Guanine has the C-6 carbonyl group that acts as the hydrogen bond acceptor, while a group at N-1 and the amino group at C-2 act as the hydrogen bond donors. Source: Internet
In the chemical synthesis, the two carboxyl groups of aspartic acid are joined into an anhydride, and the amino group is protected by converting it to a functional group that will not interfere in the next reaction. Source: Internet
Deamination occurs when an amino group is lost and is a mutation that often results in base changes. Source: Internet
