The Simplest Aldotriose Is

Question

The simplest aldotriose is:
A) acetone
B) dihydroxyacetone
C) glyceraldehyde
D) threose

Accepted Answer

An aldose that contains three carbons is an aldotriose. Among the given options, only glyceraldehyde is an aldotriose. Acetone is a ketone and does not have a carbon chain with OH groups. Dihydroxyacetone is a ketotriose and has a ketone group instead of an aldehyde group. Threose is an aldose that contains four carbons and is therefore not an aldotriose.
