一般說明

L-乳酸钠是一种来源于L-乳酸的有机酸,天然存在于体内,有助于pH调节、酸碱平衡和各种生理过程,包括通过科里循环进行的能量代谢。其多功能特性包括抗微生物作用,这种作用是通过创造一种抑制有害细菌生长的酸性环境来实现的。在代谢途径中,L-乳酸钠可以高效转化产生能量,在一些情况下可能优于葡萄糖摄取,可以将脂肪酸用作替代能源,刺激线粒体增加ATP的生成,这一点说明它在细胞能量效率的优化中起一定作用。此外,研究暗示它具神经保护功能,可以保护神经元细胞免于高脂肪膳食导致的死亡,并解决潜在的肥胖相关神经组织退化问题

L-乳酸钠的多方面特性使其成为细胞代谢、神经保护、抗微生物和营养科学研究中的重要分子,其多样化的特性(包括高效的能量转化、神经保护作用和强大的抗微生物活性)有助于加深我们对这些科学领域的理解。

應用

L-乳酸钠已用于:
  • 作为人乳腺上皮细胞系(MCF10A)[1]以及树突状细胞培养的一种培养基补充剂及细胞能量来源[2]
  • 作为原代肝细胞中肝葡萄糖产生检测中的糖异生底物[3]
  • 在葡萄糖生产培养基中用于人胚胎肾(HEK293T)细胞中的葡萄糖产生检测[4]
  • 作为骨髓来源巨噬细胞中乳酸检测的校准标准品[5]

生化/生理作用

L-乳酸是通过乳酸脱氢酶从丙酮酸中产生。乳酸的生成发生在无氧糖酵解或具有增殖活性的细胞中。[6]

文章

Sigma article discusses tumor cell metabolic pathways, focusing on aerobic glycolysis and mitochondrial activity.

本文介绍了增殖活性细胞为何需要碳源和氮源合成大分子。尽管大部分肿瘤细胞利用有氧糖酵解途径并分流线粒体氧化磷酸化代谢物,但许多肿瘤细胞表现出线粒体活性增加。

沃伯格效應會增強腫瘤細胞中葡萄糖到乳酸的轉換,而不受氧氣水平的影響;自 1924 年起就開始影響癌症新陳代謝。

Warburg effect enhances glucose to lactate conversion in tumor cells, regardless of oxygen levels; impacting cancer metabolism since 1924.

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
