Glucose
CHXII14:BIOMOLECULES

324635 Glucose is found to exist in two different \(\mathrm{\alpha}\) and \(\mathrm{\beta}\) crystalline forms. These forms can be obtained by.
(i) The \(\mathrm{\alpha -}\) form of glucose is obtained by crystallisation from concentrated solution of glucose at \(\mathrm{303 \mathrm{~K}}\).
(ii) The \(\mathrm{\beta -}\) form of glucose is obtained by crystallisation from concentrated solution of glucose at \(\mathrm{303 \mathrm{~K}}\).
(iii) The \(\mathrm{\beta-}\) form is obtained by crystallisation from hot and saturated aqueous solution at \(\mathrm{371 \mathrm{~K}}\).
(iv) The \(\mathrm{\alpha -}\) form is obtained by crystallisation from hot and saturated aqueous solution at \(\mathrm{371 \mathrm{~K}}\).
