Phytosterol Structure and Composition in the Chemosystematics of the Caryophyllales

  • John H. Adler

Abstract

Angiosperms synthesize a diverse array of 4-desmethylsterols which vary primarily in position and number of double bonds as well as stereochemistry at C-241, 2. The high degree of structural chemistry1, 2 associated with sterols, their essentiality for proper eucaryotic cell function3, 4, 5, and their ubiquitous distribution in the plant kingdom1,2 make phytosterols potentially useful molecules for the characterization of taxonomically related organisms. Most angiosperms produce 24α-alkyl-Δ5-sterols with relatively few species producing 24-alkyl-Δ7-sterols as dominant sterols1,2.
