Protecting groups can be used to create "disarmed" examples of these compounds through resonance-stabilized oxocarbenium intermediates. The osazone reaction was invented to differentiate versions of these compounds differing by one position. Biomarkers called AGEs (ay gee eez) result from iteratively adding these compounds, which are homologated in the Kiliani-Fischer reaction. Anomers are a type (10[1])of chiral epimer specific to these compounds. Two classes of these compounds named for pyran and furan are produced through the formation of hemiacetal groups. D and L enantiomers are defined with respect to the configuration of one of these compounds, which form glycosidic bonds when polymerizing. For 10 points, name these biomolecules that include maltose and glucose. ■END■
