the chemicals in a fingerprint are related to the secretion of certain sweat glands. fingerprints generall have eccrine gland secretiions (generally found on palms of hands and soles of feet, generally where there is no hair). however they could be contaminated by secretions from other glands as in apocrine(rare) and sebaceous.
