Application

L′acido L-ascorbico può essere utilizzato come standard di riferimento nella quantificazione di analiti in campioni di succhi di frutta e verdura mediante un sistema ad iniezione in flusso con l′enzima ascorbato ossidasi immobilizzato.[1]
Per maggiori informazioni sulla tecnica strumentale adatta, consultare il certificato d′analisi del prodotto. Per ulteriore supporto, contattare il Servizio Tecnico.

General description

Nelle piante l′acido L-ascorbico svolge il ruolo di antiossidante regolando il meccanismo delle specie reattive dell'ossigeno per formare perossidi ridotti.[2] È presente in abbondanza nelle piante superiori, nelle quali cui agisce come antiossidante non enzimatico.[2] Viene sintetizzato in diversi tipi di piante e nei mammiferi, tranne che nei primati e nei porcellini d′India.[3] È comunemente impiegato nella prevenzione dello scorbuto.[3]

Domande

1–2 di 2 domande  

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

    1 risposta

    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/418/501/product-dating-information-06-25-mk.pdf

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

    1 risposta

    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
