Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which biomolecule’s monomers are held together by glycosidic bonds?
A
Nucleic Acid
B
Protein
C
Lipid
D
Carbohydrate
Explanation: 

Detailed explanation-1: -Polysaccharides. A long chain of monosaccharides linked by glycosidic bonds is known as a polysaccharide (poly-= “many”).

Detailed explanation-2: -A glycosidic bond is a bond present in disaccharides and polysaccharides. This is a bond formed between two adjacent monosaccharides. Like peptide bond, elimination of a water molecule accompanies the formation of a glycosidic bond as well. In other words, it is a dehydration reaction.

Detailed explanation-3: -When carbohydrate monomers bond together, they form covalent bonds through a condensation reaction. These links are called glycosidic bonds and are named more specifically by the numeric carbon to which it bonds.

Detailed explanation-4: -The monomer of carbohydrates is a monosaccharide with the basic formula of a carbon, two hydrogen and an oxygen molecule (CH 2 0) 12 . Glucose, a product of photosynthesis, is simple sugar and a monomer with the chemical formula C 6 H 12 O 6. Glucose is commonly known as corn sugar or blood sugar.

Detailed explanation-5: -Covalent bonds result from a sharing of electrons between two atoms and hold most biomolecules together.
