Armpit sweat smells stronger than back sweat because skin bacteria break down lipid-rich secretions from apocrine glands.

Is it true that Armpit sweat smells stronger than back sweat because skin bacteria break down lipid-rich secretions from apocrine glands?

Unclear. Several sources partially support the claim: a review notes axillary odor is considered the most pungent and linked to apocrine secretions, a Stack Exchange answer says apocrine sweat is lipid-rich and bacteria metabolize it into odorous by-products, and a genetics article confirms apocrine sweat is oily and made odorous by skin bacteria. None directly compares armpit sweat strength to back sweat or fully establishes the causal mechanism as stated.
