Medically reviewed by Jay N. Yepuri, MD Liver enzymes are proteins in your liver that speed up chemical reactions. If your liver is damaged, blood tests will show abnormally high levels of these ...

Digestive enzymes are found in the digestive system, including the mouth, stomach, and small intestine. They help you break down food and absorb nutrients. Sometimes, the body cannot make enough ...

How does your body speed up these important reactions? The answer is enzymes. Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a ...

A deeper look into the apparent self-defense mechanisms of these bacteriophage-resistant bacteria revealed their secret weapon: a group of enzymes called restriction endonucleases, or restriction ...
