Which enzymes are used for carbohydrate digestion?
Mechanical digestion is the same thing as chewing, or mastication. It does not need any digestive juices, because that is considered chemical digestion. Chemical digestion in the mouth during chewing is mainly by the aid of saliva which has, among other enzymes, salivary amylase which initiates carbohydrate digestion.
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.
Pancreatic enzymes assist digestion of all three major types of nutrients- proteins, carbohydrates and fats. The pancreatic enzymes that assist digestion of the above nutrients are as follows: Proteins - Trypsin, chymotrypsin & carboxypolypeptidase Carbohydrates - Pancreatic amylase Fats - Pancreatic lipase, cholesterol esterase & phospholipase
