Peptide bonds absorb strongly around 190 to 230 nanometres. All three components have them, in proportion to their length. Aromatic residues, where present, add a weaker band near 280. Benzyl alcohol from the diluent adds its own aromatic absorbance. The region is informative about total content and uninformative about composition.
This is why HPLC separates first and detects second.
Copper(II) d-to-d transitions produce a broad, weak absorption in the visible that the plain peptides lack entirely. Its position and intensity depend on the coordination environment, so a shift reports a change in how the copper is held. In the blend it is a window onto one component.
It is weak enough that a concentrated solution is needed to measure it well.
Confirm that copper is complexed, estimate total peptide, and flag a gross change. It cannot resolve three components or quantify any one of them. Those are chromatography and mass spectrometry questions.
The GLOW blend is supplied by REVIVE LAB UAE for laboratory research use only, with batch identity by mass spectrometry and purity by HPLC. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
