This peculiar difference in acetal linkages results in a major difference in digestibility in humans. Polysaccharides are complex carbohydrate polymers consisting of more than 2 monosaccharides linked together covalently by glycosidic linkages in a condensation reaction.

Carbohydrates containing thousands of glucose units joined by alpha or beta this form of starch is a polymer of glucose joined by alpha glycosidic linkages.

Lactose forms a beta 1-4 linkage. Polysaccharides are sugar polymers that make up starch and glycogen.

A covalent bond forms between a carbohydrate molecule and another molecule (in this case, between two monosaccharides).

Cellulose. complex carbohydrate composed of glucose units joined together by 1,4 beta glycosidic linkages. Cellulose is a linear polysaccharide polymer with many glucose monosaccharide units.

These form disaccharides and oligosaccharides. Sucrose and lactose are examples of disaccharides. Sucrose creates an alpha 1-2 linkage.

Many NDOs are not digested by humans because the human body lacks the enzymes required to hydrolyze the β-links formed among the units of some monosaccharides. Such compounds include carbohydrates where fructose, galactose, glucose and/or xylose are the monosaccharides units presents.

Glycogen is even more highly branched than amylopectin. Polymers . Polymers are large molecules built from small units (monomers).
