Guanidine shows strong basicity since positive charge in guanidinium ion (protonated guanidine) is delocalized to the three nitrogen atoms in it. The isoelectric point (pI) of arginine is 10.76, which is the highest among the protein amino acids. Adult humans are able to biosynthesize arginine, ...
Consequently, arginine is 100% protonated with a net charge of +1 at physiological pH. Ammonia intoxication results in children (and cats) if this amino acid is absent from a fasting diet. It is present in high amounts in immature seeds like groundnuts....
and they are vital to many processes in the body as well. There are 20 main amino acids used by the body, and they all consist of a central carbon that is bonded to an amino group, a carboxyl group, a hydrogen, and a unique side chain that makes...
Arginine (abbreviated as Arg or R) is an α-amino acid. It was first isolated in 1886 . The L - form is one of the 20 most common natural amino acids. At the level of molecular genetics, in the structure of the messenger ribonucleic acid mRNA, CGU, CGC, CGA, CGG, AGA, and AGG...
Biochemistry A 'facultatively' essential amino acid that contains a guanido group with a pKa > 12, which carries a positive charge at physiological pH; it becomes an essential amino acid when the body is under stress or injured Sources Turkey, chicken and other meats. See Unproven methods for...
Arginine, as an amino acid, has diverse kinds of footprints in biological sciences. As a free amino acid, it has some useful properties as a cryoprotectant in freeze-drying [1], as an aggregation suppressor in protein refolding [[2], [3], [4], [5], [6]], as a suppressor of opale...

Protein arginine methylation is common PTM, which does not alter the amino acid charge but instead increases the bulkiness and hydrophobicity of amino acids, thus altering the higher-order protein structure and protein–nucleic acid and protein–protein interactions. Arginine methylation is catalyzed by...
(The exponents 0 and + indicate the neutral and positive charges, respectively, of the amino acid substrates.) System B0,+-mediated transport of CAAs and NAAs is coupled to Na+ (indicated by the letter B). This system accepts a wide range of substrates, including branched and small NAAs ...
