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.
The enzyme Acid-Induced Arginine Decarboxylase (AdiA) (EC 4.1.1.19), also commonly referred to as arginine decarboxylase, catalyzes the conversion of L-arginine into agmatine and carbon dioxide. The process consumes a proton in the decarboxylation and employs a pyridoxal-5'-phosphate (PLP) cofactor , similar to other enzymes involved in amino ...
[1] [2] [3] It is a powdered nutritional supplement that contains 3 grams of calcium β-hydroxy β-methylbutyrate, 14 grams of L-arginine, and 14 grams of L-glutamine per two daily servings. [ 1 ] Juven has been shown to increase lean body mass during clinical trials in individuals with AIDS and cancer, but not rheumatoid cachexia .
Space-filling model of nicotinic acid. Nicotinic acid, [a] or niacin, [b] is an organic compound and a vitamer of vitamin B 3, an essential human nutrient. [4] [5] It is produced by plants and animals from the amino acid tryptophan. [6]
If weight loss is your goal and you're worried about feeling hungry all day, protein-packed smoothies can help keep you full, says Keri Gans, RDN, author of The Small Change Diet.
A conservative replacement (also called a conservative mutation or a conservative substitution or a homologous replacement) is an amino acid replacement in a protein that changes a given amino acid to a different amino acid with similar biochemical properties (e.g. charge, hydrophobicity and size).

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 ...
