It is composed of a ureido (tetrahydroimidizalone) ring fused with a tetrahydrothiophene ring. A valeric acid substituent is attached to one of the carbon atoms of the tetrahydrothiophene ring. Biotin is a coenzyme for carboxylase enzymes, involved in the synthesis of fatty acids, isoleucine, and valine, and in gluconeogenesis. 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.
