Answer 1

Gelatin is extracted from the animal tissue using acids, alkalies or enzymes.

Chemically, it is formed by the partial hydrolysis of the native collagen found in the animal tissue (especially bones, skin and connective tissue).  Because it is smaller in size, it is more water soluble then the original compounds (scleroproteins).
