Gelatin is a amphoteric protein derived from the heating of collagen. An amphoteric substance is one that can behave as an acid or a base, and gelatin can be produced either by pre-treating collagen with an acid or with a base. The various pre-treatments create two different varieties of gelatin called A and B.
