Chemistry of Cats: Allergies, Catnip, and Urine

This lecture explores the chemistry behind common cat-related phenomena, such as cat allergies, the pungent smell of cat urine, and the effects of catnip on felines. It delves into the composition of cat allergens, the breakdown of felinine in cat urine, and the role of cat ketone. Additionally, it discusses the molecular formula, constitution, and degree of unsaturation in organic compounds, emphasizing constitutional isomerism. The lecture also covers chemical reactions, including the energy profile, thermodynamics, and acid-base reactions. It explains the concepts of Brønsted acids and bases, association constants, and pH in relation to acetic acid.
