D- and L- designations are used to distinguish between the two possible enantiomers of the monosaccharide, galactose. From the Fischer projection, determine the designation of this monosaccharide.

a and b ) Please name the following disaccharide. They are all are D forms. For example, ?−??????????????????−?(1→4)?−?−?????????????[side]

The monosaccharide shown below is the CH₂OH OH OH beta- L- D- alpha- Он OH anomer.
