一般說明

L-α-胆碱（PC）是一种带有甘油骨架的不对称分子，天然存在于蛋黄的卵磷脂中。[1]它是一种磷酸酯，是哺乳细胞中主要的胆碱来源。它对于肝细胞低密度脂蛋白分泌至关重要。[2]它在乙酰胆碱合成中有很重要的作用，能够营养大脑。[1]PC在脂质和脂蛋白代谢中至关重要。PC生物合成途径酶缺陷会导致一系列代谢疾病。细胞内肝脏PC和磷脂酰乙醇胺（PE）比例会导致病理生理性非酒精脂肪疾病（NAFLD）。[3]它具有抗炎症功能，对于治疗炎症性肠炎很有效。[4]PC治疗法能够有效治疗良性对称性脂肪瘤病。[5]

應用

L-α-胆碱可以用于：
  • 脂质体制备[6]
  • 可用作稳定剂溶液组分，制备分散姜黄素亚微米颗粒（CSP）[7]
  • 作为免血清组分替代全血细胞[8]

生化／生理作用

脑磷脂脑中的主要结构磷脂，包含脂肪总量的约15%；主要局限于灰质。

包裝

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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
