Abstract
|
|
|
|
To elucidate the effect of chaotropic salts on the conformation of β-casein, CD studies of β-casein at various NaC1O₄ concentrations were performed. Addition of NaC1O₄ up to 1 M caused the increase of β-sheet content from 15 to 35% due to alteration of water structure. Reversibility experiments indicate that increased secondary structure of β-casein in the presence of chaotropic salt might be a form of non-classic sheet-like structure.
