If number of aldose, ketose, furanose and pyranose units present in maltose are p, q, r, s respectively. Find the value of $p + q + r + s$

Answer:

4.00

Solution:

Monomer of maltose is $α$ -D-glucopyranose. It is disaciharide, so 2 aldose and 2 pyranose forms are present in maltose.
Hence, p = 2, q = 0, r = 0 and s = 2
So, sum of p + q + r + s = 2 + 0 + 0 + 2 = 4.
