The answer is yes. Proteins are build up of amino acids and a usual amino acid consists of two H- (hydrogen) joined to a Nitrogen and grabs on to a carbon that holds a H another carbon that double bonds with an O+ (Oxygen) and an OH. The last bond in the middle carbon makes to fill its valence shell is to an ‘R’ or the radical variable side change.
