Enhanced amyloid fibril formation of insulin in contact with catalytic hydrophobic surfaces

The important protein hormone insulin, responsible for different kind of functions in our body but mainly storage of nutrients, has for a long time been used for treatment of diabetic patients. This important protein is both physically and chemically unstable. Especially during production where the insulin protein is exposed to unnatural environmental conditions such as acidic pH has this been causing problems since huge volumes of the product go to waste.In the human body…
