$\underset{C_{12}{H}_{22}{O}_{11}}{Sucrose}\stackrel{H_{2}O/H^{+}}{\to }\alpha -D\left(+\right)glucose+\beta -D\left(-\right)fructose$

This is isomeric form of Uracil, which is present in RNA

Biuret test is given by proteins and dipeptide & compounds having following groups

Hence positive test given by tripeptide & biuret.

$?$ 0.30 gm glycine is present in 100 gm protein

$\therefore$ 75 gm glycine is present in $\frac{100}{0.30}*75=\frac{1000\cancel{0}}{3\cancel{0}}*75=25*10^{3}g/mol$

Molecular structure of tetrapeptide Gly-Glu-Asp-Tyr is;

Sucrose is the disaccharides which is a non-reducing sugar, but if forms glycosidic linkage between C₁ of a - glucose and C₂ of b-fructose. Hence Assertion is correct, but Reason is incorrect.

Biuret test is given by proteins and dipeptide & compounds having following groups

Hence positive test given by tripeptide & biuret.
