Descrizione generale

La L-lisina contiene una catena laterale basica ed è idrofila in natura. Il gruppo amminico N-butile della catena laterale è protonato a pH fisiologico. In caso di degradazione, la L-lisina sviluppa corpi chetonici. La transaminazione della lisina con l′α-chetoglutarato produce acetoacetil-CoA.[1][2] La L-lisina funziona come precursore per i metaboliti secondari, come ad esempio gli antibiotici β-lattamici. Funziona inoltre come precursore per la biosintesi dell′acido α-aminoadipico.[3]

Applicazioni

La L-lisina è un α amminoacido proteinogenico essenziale utilizzato in un′ampia varietà di applicazioni. È stata utilizzata:
  • come supplemento nei terreni di coltura cellulare[4][5][6][7]
  • come substrato per enzimi quali la L-lisina ossidasi (EC 1.4.3.14)
  • come componente dei polimeri di poli-lisina
  • come substrato per gli studi sui meccanismi di ossidazione e glicazione
  • nella preparazione della lisina cobaltosa[8][9]

In beta-lactam producing microorganisms, the first step in the biosynthesis of the beta-lactam ring is the condensation of three amino acid precursors: alpha-aminoadipate, L-cysteine and D-valine. In Nocardia lactamdurans and other cephamycin-producing actinomycetes, alpha-aminoadipate is generated from L-lysine by two

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.
