Q:

What are some digestive enzymes in the human body?

A:

Quick Answer

In the human body, some digestive enzymes are amylase, lipase, pepsin, trypsin and nuclease. Digestive enzymes breakdown different types of nutrients, such as lipids, carbohydrates and proteins as digested food makes its way through the digestive tract. Digestion begins in the mouth where the enzyme amylase, which are produced by salivary glands, initiates the breakdown of carbohydrates, as noted by Boundless.

Amylase is also made in the pancreas and released into the small intestine to continue the digestion of carbohydrates that include sugars and starches so that the small intestine can absorb these nutrients. This enzyme is referred to as pancreatic amylase.

For the digestion of lipids or fats, the enzyme lipase is necessary in the body. Lipase is made mainly in the pancreas and used by the small intestine. However, the mouth and stomach can also produce this enzyme, as stated by the University of Maryland Medical Center.

Nuclease is an enzyme produced by the pancreas. It breaks down nucleic acids into nucleotides in the small intestine.

Different enzymes are important to hydrolyze proteins, including pepsin, trypsin and peptidases. The gastric glands make pepsin and release it into the stomach region of the digestive tract. The pancreas produces trypsin and the small intestine makes peptidases, which are then utilized by the small intestine to finish the digestion of protein. Most of the chemical digestion that occurs in the body is in the small intestine. After the absorption of nutrients in the small intestine, the waste products enter the large intestine and then excreted from the body.
