Under what conditions are enzymes denatured?

Answer 1

emm, neither heat nor pH will break the enzyme down [I mean break the peptide bond] but to modify its 3D structure by interupting non-convalent interactions.

the conditions under which the enzymes will be denature include extreme temperature change, extreme pH change, addition of organic solvent or detergents [all of those works by interuption non-convalent interactions] and addition of beta-mercaptoethanol (which is a sulfur-containing reducing agent), which will break disulfide bonds in enzymes.

Answer 2

Enzymes are bio organic catalysts. They are proteins and glycoproteins. Their shape is vital for their activity. Any agent that distorts their shape or breaks them down (into amino acids and sugars ) Will destroy them or at least render them useless. Heating will break them down. The heat need noy be that high 100 segrees centigrade should destroy many of them. Strong acid (& for some enzymes), will also denature them. Bases will do so too. There are proteolytic enzymes that destroy other enzymes. For example proteases, etc. This is understandable when the number of constituent amino acids are known. A few enzymes have as many as 150,000 amino acids. Most have thousands of them.

Answer 3

For denaturation of enzymes, one or more factors must be present.
1. High Temperature
2. Extreme changes of pH
3. Presence of irreversible enzyme inhibitors, e.g. heavy metal ions.

Answer 4

under all extreme conditions that can destroy the bonds that put all aminoacids together. So..these conditions are: extreme heat, a pH level strange to their enviroment, novice chemicals, etc

Answer 5

Amylase comes with the saliva. So everytime your urge for nutrition is became on via the sight of a delicious nutrition, amylase is waiting. even regardless of the undeniable fact that it is barely energetic while the nutrition is composed of starch.

Answer 6

Extreme heat or cold, or change in pH.
