Dr. Blonz: Cooking destroys enzymes
Contra Costa Times correspondent
8/15/14

There are enzymes in the metabolism of the plant while it’s alive. These plant enzymes can be destroyed by heat (cooking). But since these enzymes are just for plants, they don’t poison our bodies. The body makes its own enzymes, and the acidic stomach denatures the digestive enzyme, starts to breaking them down to their amino acid, prepare for absorption. Cooking make certain foods easier to digest and make certain plant nutrients more bioavailable for our bodies. Appropriate cooking “kills” anything that is alive in a food, but it does not poison our body.
Lactose is type of a carbohydrate presents in many dairy products, Lactase is the digestive enzyme needed to digest lactose. Lactose-intolerant occurs when the body does not produce sufficient amount of lactase (an enzyme) to digest lactose you had. If body had more lactose than handleable amount, symptoms of lactose-intolerant will be appeared. But a milk allergy is a specific sensitivity to milk protein, so lactose-intolerant and milk allergy are two different things.
Digestive enzymes are really important because they break down polymers to small building blocks; help our bodies to absorb nutrients. According to an article from ‘livestrong.com’, it says “Different enzymes break down carbohydrates, proteins and fats, and specific enzymes are needed for specific sugars.” This means there are many kinds of enzymes in our body, like protein. I believe that there are more enzymes that are not revealed.
We have learned about biomolecules, what they are made of, and a little about enzymes. This article would help me to understand better about enzymes, especially about digestive and lactose.

    • An enzyme is a specific organic catalyst (substance that speeds up reaction without being used up in the experiment) in which it binds on to a specific substrate (reactant) at the active site and lowers the activation energy required to perform that reaction. Enzymes are important biologically because, for example, the human body performs certain reactions that keep us alive and most of them react at 37 degrees Celsius (body temperature. In each of these reactions, there is an enzyme that catalyzes these reactions to lower the amount of energy needed to perform this reaction. If enzymes didn’t exist then body temperature wouldn’t be enough to perform any of these reactions properly. Enzymes have certain conditions in which it will work in. For instance, most enzymes react at certain temperatures (varies in each enzyme), most enzymes react from a pH of 6- 8, and react faster or slower according to the amount of substrate present. Altering temperature, pH level, and concentrations of enzyme and substrates may cause absolute no change to the activation energy in which the enzyme would have been denatured. In addition to these environmental factors, other molecules may react with an enzyme. These may have great to no effect on the enzymes. Those…

    Enzymes are proteins that are involved in all the chemical processes in living things. As they are made of proteins they are affected by pH and temperature. Enzymes are catalysts; they speed up chemical reactions without being changed themselves. Digestive enzymes speed up the breakdown of large food molecules into smaller ones so that the blood can absorb them. Enzymes turn a large starch molecule into thousands of tiny glucose molecules. Enzymes end in 'ase'. There are thousands of enzymes in our body but each enzyme is only specialised to do one thing, for example carbohydraise enzymes digest carbohydrates, protease enzymes digest protein.…

    Enzymes are biological molecules, or proteins, that act as catalysts. Enzymes help complex reactions so that they may occur everywhere in life. For example, when you eat meat, the proteases work to help break down the peptide bonds that occur among the amino acids. Enzymes usually work to complete one specific job which makes them specific catalysts. They also won’t be found all over the body, enzymes are found in neural cells, intestinal cells, and saliva. Enzymes are among the many organic macromolecules, they specifically belong to the proteins. Proteins are made of amino acids which link together to be folded into a three-dimensional figure. Enzymes are a different type of proteins because they make chemical reactions happen faster without…

    There are many types of enzymes and each has a specific job. Enzymes are particular types of proteins that help to speed up some reactions, such as reactants going to products. One of them is the amylase enzyme. Amylases are found in saliva, and pancreatic secretions of the small intestine. The function of amylase is to break down big molecules of starch into small molecules like glucose; this process is called hydrolysis. Enzymes are very specific; for example, amylase is the only enzyme that will break down starch. It is similar to the theory of the lock and the key. The enzyme is the lock and the key is the substrate; only the correct key could fit into the keyhole of the lock.…
