Question

Describe the similarities and differences of aminocyclitol, iminosugar, aminosugar, aminoglycoside, and glycosylamine. Shown one example for each.

Answer 1

Differentiating criteria	Amino Sugar	Imino Sugar	Aminoglycoside	Glycosamine	Aminocyclitol
Structure	In this case, the Hyroxyl group of sugar molecule is replaced by Amino/Acetylamino group	In this case, an oxygen atom of a sugar molecule is replaced by Nitrogen atom	The amino glycoside are formed by a complex of Aminosugar and a dibasic aminocyclitol. The later is connected by glycosidic linkage.	It is formed of Amino group attached to Glycosyl group and thus they are called as N-glycosides	They consist of carbon rings having Amine group(NH2) as the main functional groups.They The carbon rings are called Cycloalkanes , with at least 3 Hydroxyl groups(OH).
Uses/importance	N-acetylglucosamine forms a component of the bacterial cell wall.	Some of the Iminosugars are used as Antiviral molecules	They are mostly used as antibiotics	Now a days they are being used as glycoside mimics	They have clinical application( as antibiotics) as well as agricultural application.
example	N-acetylglucosamine , which is a glucosamine derivative is a amino sugar	1-deoxynojirimycin	Kanamycin A	Adenosine	Hygromycon B

Similarity among all-- They are all Sugar derivatives
