WebThis creates a PEPTIDE BOND between the Carbon atom in the acid group and the Nitrogen atom in the amine group. The resulting molecule is called a DIPEPTIDE. A chain of amino acids can be built up in this way - it is called a POLYPEPTIDE. A protein may contain just one polypeptide or may have two or more chains that interact. WebBonding Methods for PVC PVC material can be bonded using different joining techniques. The bonding fabricates PVC into the finished article. All welding techniques involve the application or generation of heat. The heat softens the material while pressure is applied side by side. Bonding techniques, involving adhesives, are also common.
