In this paper, it is first confirmed using NMR method, that amino acids have one or more active groups which can react with Br2 in the oscillating reaction of amino acids. They are -NH2、 -OH、 -SH and heterocyclic group of the amino acids. These active groups constitute the activation centre of the oscillating reaction. An important conclusion is that the activation centre controls the oscillating reaction and the oscllating lifetime.
