Interpretation:
Raffinose is a trisaecharide found in Australian manna and in cottonseed meal. It is composed of three different monosaccharide. Identify the monosaccharide in raffinose.
Concept introduction:
Monosaccharaides: it is the sugar and is the most basic building blocks of carbon hydrates. It can’t be further hydrolyzed. Its general formula is . Each carbon atoms that are connected to (hydroxyl) group is chiral.
Disaccharides are oligosaccharides made-up of three monosaccharaides. These three monosaccharaides are linked by glycoside bond. Bond upon hydrolysis this glycoside bond will break upon hydrolysis of raffinose gives three unit of monosaccharaides.
