Exercise-4

The common disaccharide has the molecular formula

The two forms of $\mathrm{D}$-Glucopyranose obtained from the solution of $\mathrm{D}$-Glucose are known as

The term 'invert sugar' refers to an equimolar mixture of

In a protein molecule various amino acids are linked together by

Proteins present inside the cell membrane are stabilised by:

For Aspartic acid  , the  ${\mathrm{pK}}_{{\mathrm{a}}_1},{\mathrm{pK}}_{{\mathrm{a}}_2}$ and ${\mathrm{pK}}_{{\mathrm{a}}_3}$ are $2,4$ and $13$ respectively and for Arginine  , the ${{\mathrm{pK}}_{\mathrm{a}}}_1,{{\mathrm{pK}}_{\mathrm{a}}}_2$ and ${\mathrm{pK}}_{{\mathrm{a}}_3}$ are $2,9$ and $13$ respectively.

 If $\mathrm{pI}$ of aspartic acid is $\mathrm{x}$ and of arginine is $\mathrm{y}$, then $\mathrm{x}+\mathrm{y}$ is:

Allose and Glucose are isomeric structures with similar structural formula but different configurations. If $\mathrm{D}$-Allose and $\left(\mathrm{L}\right)$-Glucose differs in configuration along ${\mathrm{C}}_1$ number of carbons$\left({\mathrm{C}}_i={\mathrm{C}}_1,{\mathrm{C}}_2,{\mathrm{C}}_3,\dots \dots .\right),$ then $\sum {\mathrm{C}}_1$is:

In the given trimer, if ${\mathrm{R}}_1=\mathrm{H};{\mathrm{R}}_2={\mathrm{CH}}_3$ and ${\mathrm{R}}_3={\mathrm{CH}}_2\mathrm{Ph}$, then the amino acids present in the trimer are:
