pectic arabinogalactan i metabolic process
"The chemical reactions and pathways involving pectic arabinogalactan I, an alpha-(1,4)-linked D-galactopyranose backbone that is substituted with alpha-l-Araf residues via the O-3 of the D-galactose residues. Arabinogalactan I can be found as a side chain of rhamnogalacturonan I."
