When the chemical structure of a molecule changes, it's maximum wavelength changes as well. This can be observed visually by a color change. That color change can be measured quantitatively using UV-Vis spectroscopy.
This week it was observed that when curcumin is reacted with yeast, there is a loss of color. This means that curcumin is undergoing a structural change. This structural change will eventually be identified using NMR. Before an NMR spectra is run, the chemical modeling software Argus Lab can be used comparatively with UV-Vis spectra to anticipate possible structural changes.
