Cephalexin disrupts the synthesis of the peptidoglycan layer of bacterial cell walls which is responsible for cell wall structural integrity. Peptidoglycan synthesis is facilitated by transpeptidases known as penicillin-binding proteins. 供应商信息 DC Chemicals Limited 认证状态： 已认证供应商 商品数： 20124件 电话： 58447131 地址： 浦东新区金豫路100号 地区： 上海市 上海市 浦东新区 联系人： Tony Cao 联系人电话： 862158447131 邮件： [email protected] 网址： www.dcchemicals.com 年贸易额： >1000万 D&C Chemicals provides a wide range of research chemicals and biochemicals including novel life-science reagents, reference compounds, APIs and Natural compounds for laboratory and scientific use.
