一般描述

核黄素是一种可溶于水的必要维生素。牛奶和鸡蛋是它的主要来源。核黄素通常与所有组织中的酶结合。核黄素在血浆中定位时,会与白蛋白和特异性免疫球蛋白结合。[1]

应用

使用(-)-核黄素通过紫外线A (UVA)激活法研究其在体外[2]的抗菌作用。[3][4]它也被用于交联星形胶质细胞的聚乙烯膜表面的胶原涂层。[5]

生化/生理作用

核黄素是活性酶辅因子核黄素5′- 单磷酸盐(也称为黄素单核苷酸或FMN)和黄素腺嘌呤二核苷酸(FAD)的前体。[1]饮食中的核黄素缺乏会导致一种定义明确的综合症,称为核黄素缺乏症,[6]核黄素对肿瘤生长和心血管疾病具有抑制作用。它的缺乏常常影响涉及氧化还原反应的代谢。核黄素对于铁吸收、胃肠道发育、神经发生、角膜血管化和角膜混浊至关重要。[1]

Questions

1–2 of 2 Questions  
  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
