Peptide Contaminants

Meaning

Peptide contaminants are unintended or unwanted chemical species present in a synthesized peptide product, which can include truncated sequences, oxidized forms, impurities from the manufacturing process, or residual organic solvents. In the context of therapeutic peptides used for hormonal regulation, the presence of these contaminants is a significant clinical concern as they can reduce the active peptide’s potency, elicit adverse immunological reactions, or introduce unpredictable biological effects. Ensuring high purity is a critical quality control step for patient safety and treatment efficacy.
