Chemistry Interview Question:

Can a protein act as a buffer?

Submitted by: Administrator

The answer is yes! Proteins are made up of amino acids and a typical amino acid has two H- (hydrogen) connected to a Nitrogen and grabs on to a carbon which holds a H another carbon which double bonds with an O+ (Oxygen) and an OH. The last bond the middle carbon creates to fill its valence shell is to an "R" or a radical variable side change.
