Chapter 28, Problem 28.22P

(a)

Interpretation Introduction

Interpretation:

The type of covalent bond joining the monomers in the biopolymer Polysaccharides has to be named.

Concept Introduction:

The polysaccharides are the sugar molecules.  The monomer units of the polysaccharide is monosaccharide.  The monosaccharides are glucose, fructose, galactose and so on.  The monosaccharide units are in pyranose or furanose ring forms.

(b)

Interpretation Introduction

Interpretation:

The type of covalent bond joining the monomers in the biopolymer Polypeptides has to be named.

Concept Introduction:

The polypeptides are the amino acid molecules.  The monomer units of the polypeptide is an amino acid.  The amino acids contains an amine group and a carboxyl group on the same compound.

(c)

Interpretation Introduction

Interpretation:

The type of covalent bond joining the monomers in the biopolymer Nucleic acids has to be named.

Concept Introduction:

The nucleic acids are made up of the monomers Nucleotides.  The Nucleotides contains nitrogen base, sugar molecule and phosphate ion.  The nitrogen base and sugar molecule are linked by N-glycosidic bond and the sugar molecule and phosphate ion are linked by ester bond.
