One mole of each of glucose and fructose require $\mathrm{x}$ and $\mathrm{y}$ moles of periodic acid respectively, for oxidation. Hence, $\frac{\mathrm{x}}{\mathrm{y}}$ is...

The pka values for the three ionizable groups$\mathrm{x},\mathrm{y}$ and $\mathrm{z}$of glutamic acid are $4.3, 9.7$ and $2.2$respectively

The isoelectric point for the amino acid is:

Glucose $+{\mathrm{NH}}_2-\mathrm{NH}-\mathrm{Ph}⟶$Product

($1 \mathrm{mole}$) ($\mathrm{X} \mathrm{gram}$)

Considering reaction took place with $100\%$ yield of major product find the value of $\mathrm{X}$

The sum of total number of moles of ${\mathrm{PhNHNH}}_2$ used with $\left[\mathrm{A}\right]$ and $\left[\mathrm{B}\right]$ is

Which of the list shown below have the correct pair of the structure of alanine in $\mathrm{pH}$ ranges $2-4$ and $9-11$ is

I. ${\mathrm{H}}_3\stackrel{+}{\mathrm{N}}-\mathrm{CH}\left({\mathrm{CH}}_3\right){\mathrm{CO}}_2\mathrm{H}$

II. ${\mathrm{H}}_2\mathrm{N}-\mathrm{CH}\left({\mathrm{CH}}_3\right){\mathrm{CO}}_2^{-}$

III. ${\mathrm{H}}_3\stackrel{+}{\mathrm{N}}-\mathrm{CH}\left({\mathrm{CH}}_3\right){\mathrm{CO}}_2^{-}$

IV. ${\mathrm{H}}_2\mathrm{N}-\mathrm{CH}\left({\mathrm{CH}}_3\right){\mathrm{CO}}_2\mathrm{H}$
