Enzymes are vital for processes to take place in our body without them they couldn’t take place.  What are enzymes exactly?   We have an many enzymes  in our body from our saliva to our pancrease.  Enzymes are specialized proteins that are produced by living cells to catalyze reactions in the body=breakdown.   Protein in the form of an enzyme acts as a catalyst.  A catalyst in action brakes down something, any chemical substance affected with the speed of reaction without being permanently altered by the reaction.  For a chemical or biochemical reaction to occur, a certain amount of energy is required=the activation energy.  Energy can be transformed from one state to another.  The role of an enzyme is to decrease the amount of energy needed to start the reaction.  Exactly how enzymes lower activation energies is not completely and fully understood but it is known that an enzyme attaches itself to one of the reacting molecules, this is called a substrate complex.  Thousands of enzymes exist but each kind can attach ONLY to one kind of substrate.  The enzyme molecule must fit exactly with the substrate molecule (just like how pieces in a jigsaw puzzle have to fit in their specific space of the picture).  Well, if the substrate and enzyme don’t perfectly match or fit properly no reaction takes place.  When they do fit perfectly the substrate molecule can react with other molecules in a synthesis reaction and when completed the enzyme is free to move on elsewhere to connect with another substrate molecule.  This whole process takes place quickly.  Clearly, enzymes are essential to the body’s overall homeostasis. (In order to lead a healthy life, we need to bring a balance in the way we lead our lifestyle.  Homeostasis is nothing but a mechanism which helps the human body maintain a balance between the internal and external environment).  Enzymes quickly perform catalyze chemical reactions and they also govern the reactions that occur.   Enzymes are named by adding the suffix “ase” to the name of their substrates.  For example there is: 

The breaking down of starches = the enzyme that does this function is amylase.  (Know this about amylase, it is present in human saliva where it begins the chemical process of digestion; that starts in our mouth. Foods that contain much starch but little sugar, such as rice and potato, taste slightly sweet as they are chewed because amylase turns some of their starch into sugar in the mouth. The pancreas also makes amylase (alpha amylase) to hydrolyse dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy.  There is even b and y amylases. Ending product on enzymes breaking down starches or carbohydrates gives us one thing only sugar.

The breaking down of sugars, like sucrose = the enzyme is sucrase.  The ending product of the enzyme is it breaks down complex sugars to more simple sugars in the body.

                                                                                                                                                                             The breaking down of fats (lipids) = the enzyme is lipase.  Lipase perform essential roles in the digestion, transport and processing of dietary lipids in most if not all living organisms (example (triglycerides, fats, oils).Most lipases act at a specific position on glycerol backbone of lipid substrate (A1,A2 or A3 in the small intestines).  For example, human pancreatic lipase (HPL) is the main enzyme that breaks down dietary fats in the digestive system, converts triglyceride substrates found in ingested oils to monoglycerides and two fatty acids.  Know that glycerol is a simple sugar compound.                                                                   

Enzymes deal with breaking down our foods because they take a major role in what we call the process digestion in the human body but notice what the ending result is of mostly every ingredient out of 3 of our food groups, which is SUGAR.  It’s because of the food already having some sugar in it but more importantly also the chemical reaction with the enzyme to allow the food to break down into smaller compounds to be utilized in the body=simpler sugar compounds which also plays a part in the entire digestion process.
