Question

What are isomers?
(biological point of view).​

Answer 1

Answer:

Isomers are compounds with identical chemical formulas, but different structures. ... Although the chemical composition is identical, the different molecular arrangements result in molecules that exhibit very dissimilar physical, chemical, and biological properties.

Answer 2

Answer:

In chemistry, isomers are molecules or polyatomic ions with identical molecular formulas — that is, same number of atoms of each element — but distinct arrangements of atoms in space. ... Two molecules that are the same stereoisomer as each other might be in different conformational forms or be different isotopologues.
