Neurokinin A is a neuropeptide that plays a crucial role in the regulation of pain, inflammation, and other physiological processes. However, during its production, several impurities may be formed, which can affect the quality and efficacy of neurokinin A. These impurities may include related peptides, amino acid variations, or chemical modifications, and their detection and removal are important for ensuring the purity and safety of neurokinin A-based drugs and research materials.
