Same name. Different molecule.
Names, fragments, analogues, salts, and formulations can change what a study actually supports.
A short marketing name may hide important differences in sequence, chemical modification, salt form, or formulation. Establish identity before comparing products or interpreting research.
A fragment is not automatically equivalent to its parent protein. A study of a licensed medicine does not verify the identity or quality of a product carrying a similar label.
Classification also matters. NAD+ is a dinucleotide coenzyme, glutathione is an endogenous tripeptide, and a modified protein is not interchangeable with every smaller peptide.
Peptoryn keeps alias and classification fields visible so you can follow the exact substance discussed by a source. Incomplete identity is a limitation, not a reason to assume equivalence.
