Box 22 Isomers same formula different structure

The simplest monosaccharides are the trioses glyceraldehyde and dihydroxyace-tone (Figure 2.10). Look carefully at the structures, and you will see that although they both share the same number of carbons (3), hydrogens(6) and oxygens (3), the way in which these atoms are arranged is different in the two sugars. Molecules such as these, which have the same chemical formula but different structural formulas, are said to be structural isomers. The different groupings of atoms lead to structural isomers having different chemical properties. When we come to look at the hexoses (six carbon sugars), we see that there are many structural possibilities for the general formula C6H12O6; some of these are shown below.

Diabetes 2

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
