Apiogalacturonans are a type of pectin found in the cell walls of Lemna and Zostera marina.[1] Substituted galacturonans are characterized by the presence of the saccharide appendant residue D-apiose in the case of apiogalacturonan, branching from a backbone of D-galacturonic acid residues. According to the Complex Carbohydrate Research Center, "[t]he backbone of these polysaccharides is resistant to fragmentation by microbial EPGs."[2]

Lemnan belongs to rare apiogalacturonic pectic polysaccharides, along with zosteran from Zostera marina.[3]
The apiogalacturonan in Lemna has been studied for several nutritional and biotechnology applications in animal models. In brief, it has been shown to have gastric-protection and immune-adjuvant properties.[medical citation needed] It is also cryoprotective and this application has been patented.
The apiogalacturonan from Zostera marina currently is used in a variety of cosmetic functions.[citation needed] The German group Beiersdorf AG holds several patents on the application of apiogalacturonan for cosmetic applications.[citation needed] Zostera marina L. was selected for its antioxidative activity and inhibition of matrix metalloproteinase-1 (MMP-1) expression.[4]
