N-Acetyl-Ser-Asp-Lys-Pro TFA

N-Acetyl-Ser-Asp-Lys-Pro (TFA) is a bone marrow-derived endogenous tetrapeptide that acts as a specific substrate for the N-terminal active site of Angiotensin-Converting Enzyme (ACE) . It is utilized in biochemical research to study ACE activity and regulation in both in vitro enzymatic assays and in vivo physiological studies.
