General description

Palmitic acid (PA), a saturated fatty acid present in the human body, accounts for 20-30% of total fatty acids (FA) in membrane phospholipids (PL) and adipose triacylglycerols (TAG). It is one of the main components of palm oil however, significant amounts of PA are also found in meat and dairy products, cocoa butter, and olive oil. PA is also present in breast milk. PA performs various fundamental biological functions at cellular and tissue levels.

Application

Palmitic acid has been used:
  • to study its effects on monocyte chemoattractant protein-1 (MCP-1) expression in adipocytes and THP-1 macrophages
  • to stimulate lipotoxicity in primary rat hepatocytes
  • in Et-bovine serum albumin (BSA) solution along with retinoic acid (RA) and retinol to study its effects on spermatogenesis or meiotic progression

Although short-term incubation of hepatocytes with oleic acid (OA) stimulates secretion of apolipoprotein B100 (apoB100), exposure to higher doses of OA for longer periods inhibits secretion in association with induction of endoplasmic reticulum (ER) stress. Palmitic acid (PA) induces ER

Saturated fatty acids (SFAs) induce hepatocyte cell death, wherein oxidative stress is mechanistically involved. Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is a master transcriptional regulator of cellular antioxidant defense enzymes. Therefore, Nrf2 activation is regarded as an effective strategy against

Questions

1–6 of 6 Questions  
  1. 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

  2. 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

  3. How long does it last in solution and how long does it last in powder form?

    1 answer
    1. This product is not assigned an expiration date, however, batches are retested every three years while stock is available. The material is soluble in chloroform at 100 mg/mL, ethanol at 30 mg/mL, DMSO at 20 mg/mL, and Dimethyl Formamide at 20 mg/mL. While it is recommended to purge stock solutions with inert gas, the long term storage and stability have not been determined. Upon dilution with aqueous buffers or medium, working solutions should not be stored longer than one day.
