1. How does Sunblock work? Sunscreen contains organic and and inorganic chemicals. The sun shines down UV Rays which are harmful to our skin. The organic chemicals in sunscreen absorb the UV Rays through their chemical bonds. As the bonds absorb UV radiation‚ the parts of the sunscreen slowly break down and release heat. The higher SPF a sunscreen is‚ the more it protects against the UV Rays the sun shines down. 2. How does detergent work? Detergents are made up of things called surfactants

The Bradford assay is dependent on the binding of the dye Coomassie Blue G250 to protein (mainly arginine)‚ in which the dye is equal to the protein concentration. When the protein is absent‚ the solution is a red-brown colour and when the protein binds‚ the pKa of the dye moves causing the dye to become blue. The anionic blue form of the dye‚ which binds to the protein‚ has a maximum absorbance of 590 nm whereas the assay reagent solution of red
