Enzymes are proteins that break down specific things. There are 3 types of
enzymes in the human body and these are:

Enzymes and Digestion

Your digestive system is like a well-organised factory, and enzymes are the specialist workers who know exactly what to break down. These incredible proteins each have one specific job - think of them as having their own superpowers for tackling different types of food.

There are three main types of enzymes working hard in your body right now: amylase, protease, and lipase. Each one targets a different food group, so nothing gets missed in the breakdown process.

Amylase is your starch-busting hero, produced in your pancreas and salivary glands. It transforms complex starches (like bread and pasta) into simple monosaccharides that your body can easily absorb. This enzyme is quite fussy though - it works best at pH 7, which is neutral conditions.

Quick Tip: Remember that amylase starts working in your mouth through saliva - that's why chewing your food properly really matters!

Protease enzymes are the protein specialists, manufactured in your stomach, small intestine, and pancreas. They slice up proteins into amino acids, which are the building blocks your muscles need. Unlike amylase, protease loves acidic environments and works best at pH 1.5-2.

Lipase handles all the fats and oils you eat, breaking them down into fatty acids and glycerol. You'll find lipase working away in your pancreas, mouth, and stomach. Here's where bile becomes the perfect teammate - this substance is made in your liver and stored in your gallbladder, and it emulsifies fats into tiny droplets so lipase can work much faster.
