Amylase
Lipases
all organs that chemically digest fat
lipase and it turns into fatty acids
The gallbladder, which is an accessory organ of the small intestines, makes bile which is secreted into the small intestine and emulsifies (breaks down) fats.
Bile salts do not digest fats. They cause the fats to become smaller and that increases the surface area so that enzymes in the digestive tract can act quickly.
Pancreatic juice contains enzymes that digest carbohydrates,fats, nucleic acids,and proteins.
The three types of digestive enzymes secreted by the pancreas are proteolytic enzymes which are responsible for the digestion of proteins, lipases, which digest fats and amylases which digest dietary carbohydrates. As well as the digestive enzymes, Insulin and Glucagon are antagonists in control of blood sugar levels an thus the levels of sugar available to the cells.
There are many different ones: amylases digest starches, proteases digest proteins, lipases digest fats, etc. in each of the main categories there are many different enzymes (biocatalysts) that act on specific things in that nutrient category.
The duodenum is the first part of the intestine; it is the place that the stomach empties it's contents into. Along with that, the duodenum is an essential digestion site. The pancreas, liver and gallbladder all secrete important digestive enzymes into the duodenum. The enzymes digest fats, proteins and fats. Much activity goes on in the duodenum, which is why the duodenum is so crucial for digestion.
Lipase enzymes digest fats (otherwise known as 'lipids'). Lipids are broken down into fatty acids and glycerol.
A living thing can live without enzymes but it would around 20 years to digest only 1 meal! That is why all living things have enzymes of some sort to digest their food in a quicker way. However, different types of enzymes speed up digestion lf different things. E.g. Amylase, which is an carbohydrate enzyme, would not be so quick to digest proteins or fats.
Your brain does the digesting of facts with commonsensides (If it's fat your thinking of then it's a group of enzymes called lipases but also bile from your liver and gall bladder help by emulsifying the fats and oils (emulsify turns it into little droplets)
Your mouth begins digesting starch. Saliva contains enzymes that help digest starch. Then when food enters your small intestine, other enzymes help digest starch. In your large intestine, bacteria help you digest starch.
