Question

Chemical nature and biological role of carbohydrates in biomolecules

Answer 1

Explanation:

Peptidoglycan(murein) is a polymer consisting of sugars and amino acids that forms a mesh-like layer outside the plasma membrane of most bacteria, forming the cell wall. The sugar component consists of alternating residues of β-(1,4) linked N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM)

Answer 2

Answer:

Carbohydrates are biological molecules made of carbon, hydrogen, and oxygen in a ratio of roughly one carbon atom ( C) to one water molecule ( H 2 O \text H_2\text O H2OH, start subscript, 2, end subscript, O). This composition gives carbohydrates their name: they are made up of carbon (carbo-) plus water (-hydrate).
