Isomers of sugars are important to life because organisms have evolved various enzymes to access the energy in each form some organisms are therefore better at getting at some forms of sugar than other forms because of the enzymes that they can use. Optical isomerism is a form of stereoisomerism this page explains what stereoisomers are and how you recognise the possibility of optical isomers in a molecule.
