Several studies report the effects of excessive use of sugars and sweeteners in the
diet. These include obesity, cardiac diseases, diabetes, and even lymphomas, leukemias, cancers
of the bladder and brain, chronic fatigue syndrome, Parkinson's disease, Alzheimer's disease,
multiple sclerosis, autism, and systemic lupus. On the other hand, each sugar and sweetener
has a distinct metabolic assimilation process, and its chemical structure plays an important
role in this process. Several scientific papers present the biological effects of the sugars
and sweeteners in relation to their chemical structure. One important issue dealing with the
sugars is the degree of similarity in their structures, focusing mostly on optical isomerism.
Finding and developing new sugars and sweeteners with desired properties is an emerging
research area, in which in silico approaches play an important role.
