8. Peptidoglycan is made up of

(a) proteins only

(b) lipids only

(C)proteins and lipids

(d)proteins and carbohydrates​

Answer 1

Answer:

It is made up 2 alternating molecules , as following ...

N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM)

Explanation:

A peptidoglycan is a cross-linked polymer of sugars and short peptides that makes up the cell walls of all bacteria. When these two molecules are bonded by covalent bonding , from that time it is known as Glycan Chain.

Answer 2

Peptidoglycan is made up of proteins and carbohydrates​

Explanation:

Peptidoglycan produces a strong mesh like structure which provides a structure to the cell. Bacteria is considered as the unicellular organism thus peptidoglycan provide a very important role to the bacteria. It provides strength to the outer structure of the organism.

This peptidoglycan consists of single domain protein in them. It also consists of a complex structure of polymeric carbohydrates. This type of polymeric carbohydrate consists of alternating N-acetylglucosamine and N-acetylmuramic in it. Peptidoglycan consists of both protein and carbohydrates.
