Which nutrient does the enzyme present in saliva begin to digest?
Answer and explanation
Correct answer: Starch
Saliva contains the enzyme salivary amylase, also called ptyalin. This enzyme acts on starch, which is a complex carbohydrate, and begins converting it into simpler sugars in the mouth. Fat and protein digestion mainly starts later with other enzymes, while vitamins do not require enzymatic digestion in this way. Hence option A is correct.
