• yield
  • The last step of the synthesis is deprotection of the β-ring double bond of 5 with p-TsOH, aqueous dioxane, and heat (80 °C) to yield β-sitosterol 6. (wikipedia.org)
  • levels
  • High levels of β-sitosterol concentrations in blood have been correlated with increased severity of heart disease in men having previously suffered from heart attacks. (wikipedia.org)
  • itself
  • This led to suspicion that some athletes testing positive on boldenone undecylenate didn't actually abuse the hormone itself but consumed food rich in β-sitosterol. (wikipedia.org)
  • effects
  • Whether or not the down-regulation is due to accumulated sitosterol is still debatable, but most recent data indicate that secondary effects of unknown regulators other than sitosterol can lead to reduced HMG-CoA reductase activity in the disease. (wikipedia.org)
