Chemical change occurs
The substance produced as a result of a chemical reaction is called a product. It is formed when reactants undergo a chemical transformation, resulting in new substances with different properties. The products are the end result of the reaction and are often used in various applications.
Souring milk involves a chemical change where lactic acid is produced by the fermentation of lactose in milk by bacteria. This is not the result of combining an acid and a base, but rather the conversion of lactose (a sugar) into lactic acid.

Usually, sore muscles are a result of a build-up of lactic acid. Lactic acid molecular formula is C3H6O3, or 3 carbon, 6 hydrogen, and 3 oxygen.
Oxidation and reduction reactions are chemical processes that result in a gain or loss of electrons from reactant species. In oxidation, a species loses electrons, while in reduction, a species gains electrons. This transfer of electrons leads to changes in the oxidation states of the elements involved in the reaction.
