In: Biology
The carbohydrates of mammalian tissues include , while the carbohydrates of bacteria include .
a. |
galactosamine…. glucosamine |
|
b. |
lactose… sucrose |
|
c. |
hemiacetals… hemiketals |
|
d. |
proteoglycans… peptidoglycans |
|
e. |
NAG… NAM |
The right option is (d) proteoglycan.... peptidoglycan
Explanation:
Galactosamine: It is a sugar-protein compound derivative of galactose sugar. It is found in the metabolite of humans, and some bacteria and fungal cell walls contain galactosamine. [ so it is the wrong option]
Glucosamine is a sugar-protein that naturally found in bones, bone marrow, shellfish, and fungus. [not in bacteria so wrong option]
lactose: It is a sugar found in milk.
Sucrose: This is table sugar (a disaccharide of glucose and fructose). [not produced in bacteria]
Hemiacetals and hemiketals: A hemiacetal or a hemiketal is a compound that forms after the addition of an alcohol to aldehyde or ketone, respectively. [wrong option]
Proteoglycans and peptidoglycans: proteoglycans are sugar amino protein that found on the cell membrane of mammalian, and peptidoglycans are a sugar-peptide carbohydrate that consists cell wall of bacteria. [ So it is the right option]
NAG and NAM: NAG (N-acetyl glucosamine) and NAM (N-acetyl muramic acid) are components of peptidoglycans. [so it is the wrong option]
