Distinguish between structural and optical isomers in carbohydrates describing examples of each

Answer and explanation;

Structural isomers have the same molecular formula but their atoms are linked in different sequences. For Example, fructose and glucose are structural isomers because, although they have the same molecular formula (C6H12O6), glucose contains an aldehyde group (it is an aldose) and fructose contains a keto group (it is a ketose).  

In contrast, optical isomers are identical in every way except that they are mirror images of each other. The two ring forms of glucose, alpha and beta glucose, are optical isomers, being two mirror image forms.

the binding of the substrate is dictated by the shape of each molecule. side chains on the enzyme interact with the substrate in a specific way, resulting in the making and breaking of bonds.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .
