Amylase
Function: Amylase is an enzyme that is responsible for the breaking of the bonds in starches, polysaccharides, and complex carbohydrates to be turned into simple sugars that will be easier to absorb.

Clinical Significance: Amylase also has medical history in the use of Pancreatic Enzyme Replacement Therapy (PERT). One of the components is Sollpura (liprotamase), which help in the breakdown of saccharides into simple sugars.

Lysozyme
Function: An enzyme that is produced by animals that forms part of the innate immune system and is abundant in the secretions of saliva, human milk, tears, and mucus. It functions as an antimicrobial agent by splitting the peptidoglycan component of bacterial cell walls, which then leads to cell death.

Clinical Significance: Toxic levels of blood are caused by the excessive production of lysozyme's by cancer cells. Lysozyme's have also been associated with Bronchopulmonary dysplasia (BPD) in newborns and is a key factor in providing the immunology of infants during breast feeding.

Sucrase
Function: Sucrase is a stomachs related protein that mobilizes hydrolysis to convert sucrose into glucose and fructose.

Clinical Significance: Low amounts of Sucrose also known as Sucrose intolerance happens when sucrose isn't being discharged in the small digestive tract. A result of this is extra gas.

Lactase
Function: lactase is located in the small digestives system of people and other creatures such as mammals. Lactase is the bases of the total absorption of milk.

Clinical Significance: People who are lactose intolerant have medicine that can help with the digestion. When you are lactose intolerant you might experience gas, bloating, and pain along with other symptoms regarding your digestive system.
