This list of pharmaceutical compound number prefixes provides codes used by individual pharmaceutical companies when naming their pharmaceutical drug candidates. . Pharmaceutical companies generally produce large numbers of compounds in the research phase for which it is impractical to use often long and cumbersome systematic chemical names, and for which the effort to generate nonproprietary ...
In bioinformatics and biochemistry, the FASTA format is a text-based format for representing either nucleotide sequences or amino acid (protein) sequences, in which nucleotides or amino acids are represented using single-letter codes. The format allows for sequence names and comments to precede the sequences.
Chemical formula: C 6 H 14 N 4 O 2 Molar mass: 174.2 g·mol −1 Systematic name: 2-amino-5-(diaminomethylidene amino)pentanoic acid Abbreviations: R, Arg Synonyms: 2-amino-5-guanidinopentanoic acid
[17] [18] Additional, dietary arginine is necessary for otherwise healthy individuals temporarily under physiological stress, for example during recovery from burns, injury or sepsis, [18] or if either of the major sites of arginine biosynthesis, the small intestine and kidneys, have reduced function, because the small bowel does the first step ...
Following is a table listing the one-letter symbols, the three-letter symbols, and the chemical properties of the side chains of the standard amino acids. The masses listed are based on weighted averages of the elemental isotopes at their natural abundances. Forming a peptide bond results in elimination of a molecule of water. Therefore, the ...

In enzymology, an arginine—tRNA ligase (EC 6.1.1.19) is an enzyme that catalyzes the chemical reaction. ATP + L-arginine + tRNAArg AMP + diphosphate + L-arginyl-tRNAArg. The 3 substrates of this enzyme are ATP, L-arginine, and tRNA(Arg), whereas its 3 products are AMP, diphosphate, and L-arginyl-tRNA(Arg).
The chemical conversion of arginine to citrulline, known as citrullination or deimination. Citrullination or deimination is the conversion of the amino acid arginine in a protein into the amino acid citrulline. Citrulline is not one of the 20 standard amino acids encoded by DNA in the genetic code.
