II. Analysis. Given below is a schematic diagram for a simple analysis of a novel tetrasaccharide isolated from a new species of red algae. Analyze each step and the accompanied results of tests, and answer the succeeding questions: a1,4-endoglycosidase treatment B Benedict's test: (+) Seliwanoff's test: (-) Bial's-Orcinol test: (+) 2N HCI, 100C, 60 mins. Fehling's test: (+) Seliwanoff's test: (-) Bial's-Orcinol test: (-) Osazone test: needle- like crystals, formed 5 mins. Benedict's test (-) TLC Profile conc.
