Question

Select the option that correctly identifies the chemical bonds present in the given biomolecules.
Polysaccharides - A, Proteins - B, Fats - C, Water - D

	A	B	C	D
(a)	Ester	Peptide	Glycosidic	Hydrogen
(b)	Glycosidic	Peptide	Ester	Hydrogen
(c)	Glycosidic	Peptide	Hydrogen	Ester
(d)	Hydrogen	Ester	Peptide	Glycosidic

• A. a
• B. b
• C. c
• D. d

Answer 1

Answer: (B)

In polysaccharides, monosaccharides are linked together by glycosidic bond (C-O-C). It is formed by dehydration between two carbon atoms of two adjacent monosaccharides. Water has hydrogen bonding. Amino acids in a protein are linked through peptide bond whereas ester bond is present in fats.
