Ac-Arg-pNA·HCl, also known as Acetyl-Arginine-p-nitroanilide hydrochloride, is a synthetic peptide derivative commonly used in biochemical research, particularly in studies involving proteolytic enzymes. This compound features an acetylated arginine residue linked to a p-nitroanilide moiety, which serves as a chromogenic substrate for various proteases. The acetylation enhances the stability and solubility of the peptide in aqueous solutions. As a hydrochloride salt, it is typically more soluble in water, facilitating its use in laboratory settings. The p-nitroanilide group is crucial for colorimetric assays, as its cleavage by proteases results in a measurable color change, allowing for the quantification of enzyme activity. Ac-Arg-pNA·HCl is characterized by its relatively low molecular weight and specific functional groups that contribute to its reactivity and interaction with enzymes. It is essential to handle this compound with care, following appropriate safety protocols, as with all chemical substances used in research.
