Backbone chain
Encyclopedia
In polymer science, the backbone chain or main chain of a polymer
is the series of covalently bonded atom
s that together create the continuous chain of the molecule
.
The backbone contains an amino group, a carboxylic acid group, and a central carbon. However, the backbone does not contain a R-group.
