HUMAN NUTRITION

Detailed explanation-1: -Oligosaccharide is the short chain of monosaccharide unit which composed of 3-10 molecules connected by glycosidic linkage. The most common example of oligosaccharide is raffinose. It is a trisaccharide found in many plants and composed of galactose, glucose and fructose.

Detailed explanation-2: -A long chain of monosaccharides linked by covalent bonds is known as a polysaccharide (poly-= “many”). The chain may be branched or unbranched, and it may contain different types of monosaccharides. Polysaccharides may be very large molecules. Starch, glycogen, cellulose, and chitin are examples of polysaccharides.

Detailed explanation-3: -Oligosaccharides have a few sugars, typically 3 – 15 linked together with glycosidic bonds, while polysaccharides tend to have many monosaccharides linked together by glycosidic bonds.
