|Biological Activity or Inhibitors:|| 1.Cerebroside B1b has antiulcerogenic activity.
|Storage:||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

|After receiving:||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.|

|Δ10(E)-Sphingolipid Desaturase Involved in Fusaruside Mycosynthesis and Stress Adaptation in Fusarium graminearum.[Pubmed: 25994332]|
|Heterologous expression of Δ10(E)-SD in Pichia pastoris has been established to facilitate a reliable generation of 1 through the Δ10(E)-SD catalyzed desaturation of Cerebroside B (2), an abundant fungal sphingolipid. Site directed mutageneses show that the conserved histidines of Δ10(E)-SD are essential for the 10,11-desaturation catalysis, which is also preconditioned by the C9-methylation of the substrate. Moreover, Δ10(E)-SD confers improved survival and faster growth to fungal strains at low temperature and high salinity, in parallel with to higher contents of 1 in the mycelia.|

|Steroids and phenolic constituents from the fruiting bodies of the basidiomycete Sarcodon joedes.[Pubmed: 22320163]|
|Nine secondary metabolites, including four steroids, four phenolics and one cerebroside, were isolated from the methanol extract of the fruiting bodies of the basidiomycete Sarcodon joedes. The isolated compounds were identified by spectroscopic analyses as (22E,24R)-6β-methoxyergosta-7,22-diene-3β,5α-diol (1), 2',3'-diacetoxy-3,4,5',6',4″-pentahydroxy-p-terphenyl (2), Cerebroside B (3), ergosta-7,22-dien-3β-ol (4), ergosterol peroxide (5), (22E,24R)-3β-hydroxy-ergosta-5,22-dien-7-one (6), benzoic acid (7), methyl p-hydroxybenzoate (8) and 3,4-dihydroxybenzoic acid (9). The cytotoxic activities of these compounds were evaluated. All these compounds were isolated from this fungus for the first time.|
