[Characteristic of binding forms of arsenic in polluted rice seed and their stability].
The protein-binding forms of As in polluted rice seed and their stability were studied using the methods of Sephadex chromatography. The results showed that As in rice seed was mainly combined with the proteins with apparent molecular weights of 54.5 KD and 5.5 KD. The protein-binding form of As (54.5 KD) was unstable, and was easily decomposed into stable and tiny molecular under the treatment of steaming and digestive enzyme.
