The structure and composition of proteins

Principle
When protein is heated, carbon, water and ammonia are formed. The black residure on combustion is identifiable as carbon. Ammonia colours universal indicator paper blue and has a pungent smell. Water changes the colour of water indicator paper to blue. Protein is composed of the four basic elements carbon, hydrogen, oxygen and nitrogen.
