“…Methylamine has been detected in human urine, blood, and tissues. − It can be derived from several metabolic reactions, such as the deamination of adrenaline, sarcosine, creatinine, choline, and lecithin. − It has been suggested that methylamine and other related short-chain aliphatic amines may play a significant role in the central nervous system disturbances observed during hepatic and renal disease, especially when the blood–brain barrier is compromised . In addition, amino functional groups (NH 2 ) occur frequently in biomolecules, for example, amino acids molecules. , The biological functions of methylamine and other biomolecules containing NH 2 are intimately connected to their hydrated structures. − Therefore, studying the hydration of methylamine is essential for biological science.…”
