• plasma
  • These sterols localize to the plasma membrane of cells, where they play an important structural role in the regulation of membrane fluidity and permeability and also influence the activity of enzymes, ion channels, and other cell components that are embedded within (Daum et al. (wikipedia.org)
  • Plasma levels of fat-soluble vitamins and other vegetable-derived compounds have been studied following plant sterol ingestion due to concerns about the possibility of reduced absorption. (wikipedia.org)
  • plant
  • citation needed] Plant sterols have traditionally been considered non-absorbable. (wikipedia.org)
  • This may be of importance since elevated plant sterol concentrations have been identified as an independent risk factor for coronary heart disease (CHD). (wikipedia.org)
  • Two ABC transporters (ABCG5 and ABCG8) play an important role in the regulating the intestinal absorption of plant sterols by resecreting previously absorbed plant sterols from the enterocytes back into the intestinal lumen. (wikipedia.org)
