What enzymes breakdown the macronutrients in the mouth?

In the mouth, salivary amylase is the primary enzyme that begins the breakdown of carbohydrates, specifically starches, into simpler sugars. Additionally, lingual lipase, secreted by glands on the tongue, starts the digestion of fats, although its activity is more pronounced in the stomach. There's no significant enzymatic breakdown of proteins in the mouth; that process primarily occurs in the stomach and small intestine.
