Arginine is the amino acid with the formula (H 2 N)(HN)CN(H)(CH 2) 3 CH(NH 2)CO 2 H. The molecule features a guanidino group appended to a standard amino acid framework. At physiological pH, the carboxylic acid is deprotonated (−CO 2 −) and both the amino and guanidino groups are protonated, resulting in a cation.
Examples of guanidines are arginine, triazabicyclodecene, saxitoxin, and creatine. Galegine is an isoamylene guanidine. [19] See also. Sakaguchi test; Y-aromaticity;
Arginine has a charged guanidino group and lysine a charged alkyl amino group, and are fully protonated at pH 7. Histidine's imidazole group has a pK a of 6.0, and is only around 10% protonated at neutral pH.
Few foods are more appetizing to people than a juicy steak. Grilled to order and garnished with herbs like basil and chives, sauces such as au jus, peppercorn and A1, or vegetables like grilled ...
U.S. News & World Report just rated the Mediterranean diet as the No. 1 diet for the eighth year in a row. Not only did it win best overall diet, it also won the top spot for managing diabetes ...
It is structurally equivalent to a one-methylene group-higher homolog of arginine and to the guanidino derivative of lysine. L -Homoarginine is the naturally-occurring enantiomer . Physiologically , homoarginine increases nitric oxide (NO) supply and betters endothelial functions in the body, with a particular correlation and effect towards ...
Glycocyamine (or guanidinoacetate) is a metabolite of glycine in which the amino group has been converted into a guanidine by guanylation (transfer of a guanidine group from arginine). In vertebrate organism it is then transformed into creatine by methylation. Glycocyamine is used as a supplement and as a feed additive in poultry farming.
L-Arginine:glycine amidinotransferase (AGAT; EC 2.1.4.1) is the enzyme that catalyses the transfer of an amidino group from L-arginine to glycine. The products are L-ornithine and glycocyamine, also known as guanidinoacetate, the immediate precursor of creatine. Creatine and its phosphorylated form play a central role in the energy metabolism ...
