Why is it necessary to denature casein to isolate it? Explain what the chemical process of hydrogenation does to fats. What are Colloids ? What do colloids do? What is the purpose of masking interfering agents? (a) What are fillers and reinforcing agents? (b) What is their purpose? Why ...
Chemical solvents such as ethanol and isopropanol are frequently used for sterilizing surfaces and equipment. These solvents denature proteins. They are most effective when diluted to concentrations between 60% and 90%. While they are effective against microbial cells, they do not eliminate spores. Ra...
but not the larger protein structure that prevents the enzymes from doing their job. And so, a major task of digestion is first to denature the incoming proteins, and this process beginsin your stomach.

This is the point at which enzyme activity is at its maximum level. Once this is reached the rate of reaction slows down until it stops all together for the enzyme to function. The heat causes the enzyme to denature, the enzyme changes in structure and shape of the ...
What is it used for? What is the purpose and procedure of 'digesting the precipitate'? What is the purpose of washing an organic solvent with water in a separatory funnel? What precautions must be taken when using a centrifuge? Why does chromatography work? Why is it necessary to dena...
The clearing agent added in this step displaces ethanol and removes fat from the tissue (clears the tissue) to allow the paraffin wax to fully penetrate the tissue for the final preservation step. Xylene is a commonly used clearing agent, but due to its toxicity, isopropanol is often used ...
Isopropyl alcohol is a colorless, combustible liquid. Also known as rubbing alcohol, isopropyl alcohol is a mainstay of both...
of TRIzol®controls to separate RNA from DNA and protein, while a high pH can cause RNA and DNA to be isolated together. The guanidinium salt serves as a chaotropic agent to denature proteins and the phenol (commonly indicated as a pink color) is an organic compound also used to extract...
variety of starchy or sugary crops including potatoes, sugar cane and beets. In fact, ethanol can be made from anything that contains fermentable sugar, including organic garbage. Gasoline is added to E85 to improve its cold start characteristics and to denature the fuel so it cannot be ...
