Dhomoarginine
Dhomoarginine is a non-proteinogenic amino acid, meaning it is not one of the 20 standard amino acids that make up proteins. Its structure is similar to arginine, but with an additional methylene group in the side chain, making it a homochain analog. This structural difference can lead to distinct biochemical properties and interactions compared to arginine. Dhomoarginine has been identified in various biological contexts, though its specific physiological roles are not always fully elucidated. It can be found in certain food sources and has been observed in biological fluids. Research into dhomoarginine has explored its potential involvement in metabolic pathways and as a marker for certain physiological states or conditions. The synthesis of dhomoarginine in biological systems is not as well-understood as that of proteinogenic amino acids. Its metabolic fate and potential degradation pathways are also areas of ongoing scientific investigation. Due to its unique structure, dhomoarginine may interact differently with enzymes and transporters compared to arginine.
