Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A long string of simple sugars hooked together is called a:
A
polysaccharide
B
polypeptide
C
disaccharide
D
monosaccharide
Explanation: 

Detailed explanation-1: -Polysaccharides. A long chain of monosaccharides linked by glycosidic bonds is known as a polysaccharide (poly-= “many”). The chain may be branched or unbranched and may contain different types of monosaccharides.

Detailed explanation-2: -Polysaccharides may be made from thousands of simple sugars linked together. These large molecules may be used for storage of energy or for structure.

Detailed explanation-3: -Simple carbohydrates or ‘simple sugars’ include one (monosaccharide) or two sugar molecules (disaccharides). Whereas complex carbohydrates contain many sugar molecules linked together (polysaccharides).

Detailed explanation-4: -Polysaccharides are major classes of biomolecules. They are long chains of carbohydrate molecules, composed of several smaller monosaccharides.

Detailed explanation-5: -Polysaccharides are complex biomacromolecules that are made up chains of monosaccharides. The bonds that form these chains are glycosidic bonds. Commonly found monomer units in polysaccharides are glucose, fructose, mannose and galactose which are simple sugars.
