Which biomolecule are enzymes made up of?

Enzymes called amylase are found in your salivia, made in your salivia glands. The amylase helps to break down carbohydrates in your mouthbefore it goes down to the stomach. When the carbohydrates get to the stomach, more amylase needs to be added. This is because the acid in the stomach is extremely strong (pH 1) and dissolves the amylase. Another organ, called the pancreas, adds more of the amylase to the stomach, in order to digest the remaining carbohydrates. They are also many other enzymes in your body.

Good luck with biochem :)
