Structural and chemical charactertistics of pectins, arabinogalactans, and arabinogalactan proteins from conifers

摘要

In this review, we summarized the research data on the contents and chemical structures of pectic polysaccharides, arabinogalactans, and arabinogalactan proteins from coniferous species. The presently known structures of these polymers are given. Special attention is given to the description of chemical structural features of pectic polysaccharides from the Abies sibirica and Picea abies tree verdures (branches and needles). Three models presently suggested for the description of pectin macromolecular structures are discussed.
