Biomolecules Question 3
Question 3 - 25 January - Shift 1
Match items of Row I with those of Row II.
Row I :
(P)
(Q)
(R)
(S)
Row II :
(i) $\alpha$-D-(-) Fructofuranose.
(ii) $\beta$-D-(-) Fructofuranose
(iii) $\alpha$-D-(-) Glucopyranose.
(iv) $\beta$-D-(-) Glucopyranose
Correct match is
(1) $P \to$ iv, Q $arrow$ iii, $R \to$ i, $S \to$ ii
(2) $P \to i, Q \to$ ii, $R \to$ iii, $S \to$ iv
(3) $P \to$ iii, Q $arrow$ iv, $R \to$ ii, $S \to i$
(4) $P \to$ iii, $Q \to iv, R \to i, S \to 11$
