Seliwanoff test and Xanthoproteic test are used for the identification of _ and _ respectively.

Step-by-step solution

Seliwanoff test for ketose and Xenthoprotic test for proteins. Seliwanoff's test is a chemical test which distinguishes between aldose and ketose sugars. If the sugar contains a ketone group, it is a ketose. If a sugar contains an aldehyde group, it is an aldose. This test relies on the principle that, when heated, ketoses are more rapidly dehydrated than aldoses.
