Amylase, an enzyme that catalyzes the breakdown of starch into sugars, has an optimal pH and temperature range for activity. Extreme pH levels, either too acidic or too alkaline, can lead to denaturation, altering the enzyme's structure and rendering it inactive. Similarly, elevated temperatures can cause denaturation, while very low temperatures may slow down its activity significantly. Maintaining the proper pH and temperature is crucial for optimal enzymatic function.

Do Toxins from pathogenic bacteria can be destroyed by freezing and cooking?
Freezing does not effectively destroy toxins produced by pathogenic bacteria; in fact, some toxins can remain active even after freezing. However, cooking at sufficiently high temperatures can inactivate many bacterial toxins. It's crucial to cook food to the recommended internal temperatures to ensure safety. Always prioritize proper food handling and cooking methods to minimize the risk of foodborne illness.
Can tamoxifen elevate your amylase?
Yes, tamoxifen has been reported to potentially elevate amylase levels in some individuals. This elevation is usually mild and transient, and consultation with a healthcare provider is recommended for appropriate monitoring and management.
As you demonstrate in this experiment high temperature inactivate catechol oxidase how is it that some bacteria live in the hot spring Yellowstone pack at temperature as high as 73 degrees celsius?
The bacteria that live in the hot spring are of a different kind. They can survive in extreme conditions. There are also other type of bacterias that can live in salty and some which can live in acidic conditions. Also because their proteins are in their correct form when at extreme temperatures, and in fact when put at temperatures that are normal for us, their proteins would deform and they could die.
Why will salivary amylase start digesting the chips in a human mouth but not the chicken?
Salivary amylase is an enzyme that specifically breaks down starches into simpler sugars, which are abundant in carbohydrate-rich foods like chips. Chips, made primarily from potatoes, contain starch that amylase can effectively digest. In contrast, chicken is primarily composed of proteins and fats, which do not contain starch, so salivary amylase has no effect on it. Therefore, while chips will undergo some digestion in the mouth, chicken will not be affected by this enzyme.
When starch was incubated with amylase at 0 degrees did you see any starch digestion?
At 0 degrees Celsius, the activity of amylase is significantly reduced due to the low temperature, which affects enzyme kinetics and slows down the reaction rate. While some minimal starch digestion may occur, it is unlikely to be substantial. Therefore, the overall digestion of starch by amylase at this temperature would be negligible.
What is the pH range of amylase enzyme?
The pH range of amylase enzyme typically falls between 6.5 to 7.5. However, this can vary depending on the specific type of amylase and the organism from which it is derived. Some amylase enzymes may be active in a broader pH range.
Who secrets amylase?
Amylase is an enzyme that breaks starch down into sugar. Amylase is present in human saliva, where it begins the chemical process of digestion. 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. Thepancreas 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. Plants and some bacteria also produce amylase. As diastase, amylase was the first enzyme to be discovered and isolated (by Anselme Payen in 1833).[1]
Does the optimum pH of salivary amylase differ from plant amylase?
Yes, the optimum pH for salivary amylase is around pH 6.7, while the optimum pH for plant amylase can vary depending on the specific enzyme and plant species. Plant amylase enzymes may have an optimum pH range that can span from slightly acidic to neutral conditions.
Are all pathogens killed by freezing temperatures?
No, not all pathogens are killed by freezing temperatures. While freezing can inactivate many bacteria and viruses, some pathogens can survive in a dormant state and may become active again once thawed. Additionally, certain parasites and spores can also withstand freezing. Therefore, freezing is not a guaranteed method for eliminating all harmful microorganisms.
What is a amylase solution?
An amylase solution is a liquid that contains the enzyme amylase. Amylase is an enzyme that breaks down starches into sugars. It is commonly used in various industries such as food processing and biochemistry.
What does inactivate mean?
Enzyme inactivation refers to a certain period when the enzyme is unable to catalyse a particular reaction. For example some enzymes are inactivated at extreme temperatures of cold or heat. At this particular time the enzyme does not perform its function of catalysis but after favourable conditions return the enzyme wil resume its catalylitic function.
What are some enzymes found in the digestive system?
Pancreatic amylase Lipase Pepsin Salivary amylase Maltase Rennin (younger version of pepsin mostly found in babies)
What enzyme begins the breakdown of starch?
http://www.answers.com/topic/salivary-glandAmylase in the saliva is known as Ptyalin.Humans have this enzyme in their saliva, but some mammals, like horses, dogs, and cats, do not.Ptyalin begins carbohydrate and polysaccharide digestion in the mouth; the process is completed in the small intestine by the pancreatic amylase, sometimes called amylopsin.dextrin
What is the name of the enzyme in saliva and what compound is produced when this enzyme acts on starch?
the enzyme ptylin or some amylase and it converts starch to maltose
What substrate would fit into the active site of amylase?
Starch would fit into the active site of amylase. Amylase is an enzyme that catalyzes the hydrolysis of starch into smaller sugar molecules such as maltose. The active site of amylase has a specific shape that allows it to bind to the starch substrate and break it down into simpler sugars.
What precautions are needed with tube feeding?
Certain medications may interact with some formulas to inactivate the nutrients or change the way that the drug is absorbed.
