Chemical digestion is a process in which enzymes break down food in the body into smaller molecules that can be absorbed and utilized by the body. Synonyms for chemical digestion include enzymatic digestion or hydrolysis. Enzymatic digestion refers to the process where enzymes break down food into simpler molecules. Hydrolysis, on the other hand, refers to the process of breaking down a larger molecule to smaller ones, a process that helps in the chemical digestion of food. Other synonyms for chemical digestion include decomposition, catabolism, and breakdown, among others. Overall, chemical digestion is a complex process that is crucial in the human body as it helps break down food and release energy for various body functions.
