Background / Technical Information:????Microcystins are a group of cyclic heptapeptide hepatotoxins produced by a number of cyanobacterial genera. The most notable of which, and namesake, is the widespread genus Microcystis. Structurally, all microcystins consist of the generalized structure cyclo(-D-Ala1-X2-D-MeAsp3-Y4-Adda5-D-Glu6-Mdha7-). X and Y are variable L-amino acids, D-MeAsp is D-erythro-β-methylaspartic acid and Mdha is N-methyldehydroalanine. Adda is the cyanobacteria unique C20 β-amino acid 3-amino-9-methoxy-2,6,8-trimethyl-10-phenyl-deca-4,6-dienoic acid. Substitutions of the variable L-amino acids at positions 2 and 4 give rise to at least 21 known primary microcystin analogs and alterations in the other constituent amino acids result in more than 90 reported mycrocystins to date. 伊普瑞斯科技有限公司 Express Technology Co., Ltd. 北京 电 话 / Tel：+86-10-60206266 60206773 邮件：info@express-cn.com 客服QQ：1091590295（终端客户） 昆明 电 话 / Tel：+86-871-68301933 68331318 邮件：info@express-cn.com 客服QQ：674561955（经销商） www.express-cn.com 为了保证您的查询能够得到及时的回复，烦请在给我们发送电子邮件时务必注明您的单位名称和电话联络方式！
