一般描述

L-抗坏血酸用作食品添加剂、褐变抑制剂、风味稳定剂、面团改良剂和颜色稳定剂。坏血病与抗坏血酸缺乏相关。L-抗坏血酸可刺激免疫反应,并参与胶原、肉碱和神经递质合成。[1]

应用

L-抗坏血酸已用于:
  • 作为成骨分化培养基中的一种成分[2]
  • 作为分化骨髓基质细胞的MesenCult培养基组分[3]
  • 作为维生素C测定的标准品[4]
  • 防止三氯甲烷生成势(THMFP)[5]

生化/生理作用

L-抗坏血酸(L-AA)是一种可广泛获取的水溶性化合物。L-AA具有抑制低碳钢腐蚀的能力。[6]
抗坏血酸,也称为维生素C,是由植物和一些动物物种产生的六碳内酯,但人类和其他灵长类动物不能产生。抗坏血酸作为多种酶的酶促辅助因子发挥作用,用作单加氧酶和双加氧酶的电子供体。抗坏血酸也是一种强大的抗氧化剂,尤其是对活性氧类。

Questions

1–3 of 3 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.

  3. What is the validity period of this reagent?

    1 answer
    1. This product is not assigned an expiration date or recommended retest date. Customers should routinely inspect products with no expiration date or recommended retest date to ensure they perform as expected. These products are also subject to a one-year warranty from the date of shipment.
