[Plant sterols, cholesterol precursors and oxysterols: small amounts, big effects]. / Kasvisterolit, kolesterolin esiasteet ja oksisterolit: pienet määrät, suuret vaikutukset.

ABSTRACT

Noncholesterol sterols are present in the body in very low concentrations compared with cholesterol. Minor structural changes in sterols give them completely individual biological activities. Steroid hormones are the best known example of this. The knowledge of other relatives of cholesterol, particularly plant sterols, cholesterol precursors and oxysterols, their properties, physiological effects, significance in disease processes and diagnostic applications has recently undergone a rapid increase.
