Fischer projection formulas of D-aldoses

Fischer projection formulas represent the stereochemistry of D-aldoses, which are a type of monosaccharide with an aldehyde group. In these projections, the carbon chain is drawn vertically, with the most oxidized carbon (the aldehyde) at the top. The hydroxyl (-OH) groups are positioned to the right for D-aldoses when the asymmetric carbon furthest from the aldehyde group has the -OH on the right side. Common examples include D-glucose and D-galactose, which showcase this configuration in their Fischer projections.
