ground silica and spirulina mixture be suspended in deionized water because its dissolved and mixed well in water than any other solvent.

What is the color of the folded phytobilliprotein with the bound cofactor?

A blue color is observed when phytobilliprotein is folded.

How do you expect it to change as you add acid or base?

when a base solvent is use for the solution of silica and spirulina (e.g of base NaOH) is used, the colour obseved will be pale yellow or green color.

when a acidic solvent is use for the solution of silica and spirulina (e.g of base HCL) is used, the colour obseved will be colorless solution.

When a base and acidic solvent is used, it causes a changed in the charge state of the protein and changes the interaction thereby causing unfolding.
