Abstract
A Polysaccharide was isolated from lupinus termus (variety Giza 2 ) in 3-5% yield , and was purified vta its copper complex . Hydrolysis of the Polysaccharide afforded D-galactose , L-arabinose, D-xylose and L-rhamonose in molar ratio 5:3:1:1 respectively .
Periodate oxidation of the polymer resulted in the production of one molar equivalent of formic acid per ten anhydroaldose units showing that the polysaccharide is branehed . After oxidation by periodate and subsequent hydrolysis of the polyaldehyic product , none of the mono-saccharide was observed to accur in the hydrolysate thus indicating that the branching units must be D-galacto-pyranose until connected at C-6. The liberated mole of formic acid could originate only from a terninal unit which must occur once every ten units .
