1. When assaying for carbohydrates, methods that use aqueous sulfuric acid can reveal both reducing and non-reducing sugars (both give positive results). Methods that avoid aqueous acid tend to only give positive results for reducing sugars.
Aqueous 황산을 사용하면 환원당, 비환원당 둘 다 나오는데 사용하지 않으면 환원당만 나온다는데 그 이유가 뭔가요?
2. A solution of pure glucose was analyzed and found to contain a mixture of alpha and beta isomers. After treatment with mild base, the solution was found to contain two new species (A and B). The new species were each found to be reducing sugars. When isolated in pure form, A was found to produce a mixture of A and B. Similarly, pure B was found to produce a mixture of A and B. What are the most likely identities of A and B?
