STATEMENT-1 : Lysine, cysteine and threonine are highly soluble in water but serine and valine are slightly soluble.
STATEMENT-2 : Additional polar groups, such as $- O H, - N H_{2}$ and $C O O H$ increase the solubility in water appreciably.

Solution

The correct option is A STATEMENT-1 is True, STATEMENT-2 is True; STATEMENT-2 is a correct explanation for STATEMENT-1
Lysine, cysteine and threonine contains polar groups such as $- O H, - N H_{2} a n d - C O O H$ .
These groups increase the solubility in water appreciably.
However such groups are not present in serine and valine.
Hence, they are slightly soluble.
