![A chiral carbon is a carbon atom that is bonded to
four different atoms or groups of atoms. Since
monosaccharides have three to eight carbon
atoms, they tend to have more than one chiral
carbon atom.
Part A
Below is the open-chain structure of the monosaccharide D-tagatose, which is a ketohexose. Like most
monosaccharides, it has more than one chiral carbon. Select all of the chiral carbon atoms.
Identify the chiral carbon atoms by selecting each atom and assigning it a map number of 1 until
all atoms are mapped. To do this, right-click on an atom and choose Atom Properties. (Mac
users: Use an equivalent for right-clicking.) Then, clear the check mark to enable the Map field
before entering a value.
