S4857 L-Ornithine L-ornithine ((S)-2,5-Diaminopentanoic acid) has an antifatigue effect by increasing the efficiency of energy consumption and promoting the excretion of ammonia. It is one of the key reactants in the urea cycle.
S4512 Aceglutamide Aceglutamide (α-N-Acetyl-L-glutamine, N2-Acetylglutamine) is a psychostimulant, nootropic agent which functions as a prodrug to glutamine with improved potency and stability.
S4514 Acetylleucine Acetylleucine (N-acetyl-L-leucine) is a drug used in the treatment of vertigo.
S3963 DL-Glutamine DL-Glutamine (Glutamin, 2-amino-4-carbamoylbutanoic acid) is a non-essential amino acid present abundantly throughout the body and is involved in many metabolic processes.
E6833New Glyphosate Glyphosate is a non‑selective, systemic broad‑spectrum herbicide and a phosphonomethyl derivative of the amino acid glycine. It inhibits the enzyme 5‑enolpyruvylshikimate‑3‑phosphate synthase (EPSPS) in the shikimate pathway, thereby blocking synthesis of the aromatic amino acids phenylalanine, tyrosine, and tryptophan.
E7280New Xanthosine 5'-monophosphate sodium salt Xanthosine 5'-monophosphate sodium salt (XMP sodium salt) is an essential intermediate in purine metabolism, specifically the product of the rate-limiting step in guanosine monophosphate (GMP) biosynthesis. It plays a critical role in DNA, RNA, and glycoprotein synthesis.
S5970 Selenomethionine Selenomethionine (Seleno-DL-methionine, DL-Selenomethionine) is a naturally occurring amino acid containing selenium. Selenomethionine (SeMet) can substitute for methionine (Met) during protein synthesis in a non-specific manner. Due to the significant differences in their redox properties, the incorporation of SeMet in place of Met may adversely impact protein function.
