What is the common name of the sugar alcohol produced when D-galactose is reduced?
A
L-galactose
B
D-galactitol
C
D-galactaric acid
D
L-galactitol
Verified step by step guidance1
Understand the concept of sugar alcohols: Sugar alcohols are formed when the carbonyl group of a sugar is reduced to a hydroxyl group, resulting in an alcohol.
Identify the sugar involved: The problem mentions D-galactose, which is a monosaccharide sugar.
Reduction process: Reduction of D-galactose involves converting the aldehyde group (CHO) at the first carbon into an alcohol group (CH2OH).
Determine the product: When D-galactose is reduced, it forms a sugar alcohol known as D-galactitol.
Common name recognition: D-galactitol is the common name for the sugar alcohol produced from the reduction of D-galactose.
