3. without a salt bridge charge buildup will cause the cell reaction to stop. (1)Reduction occurs at the cathode. (2)A spontaneous reaction generates an electrical current in a voltaic cell. (3) without a salt bridge charge buildup will cause the cell reaction to stop.
Peptide Bonds. The joining of amino acids in the process of making biochemical molecules like proteins is done by bonds which are referred to as peptide bonds. This may be illustrated with the two simplest amino acids, glycine and alanine.
The covalent bond (C-N) bond formed by a condensation reaction between two amino acids; links the residues in peptides and proteins. polymer Any long molecule composed of small repeating units (monomers) bonded together.
