A sugar without a hemiacetal is non-reducing because it does not behave as a reducing agent toward oxidizing metal salts. Sucrose is one example of a non-reducing sugar. Different tests can work out whether sugar is reducing or non-reducing, by detecting the presence of free aldehyde or ketone groups. Sucrose is less reactive and more likely to survive the journey in the phloem.
