What is likely to happen to a protein molecule that is exposed to intense heat or radiation?
A protein may become denatured when exposed to intense heat or radiation. When a protein becomes denatured, its basic structure is damaged enough that it is no longer able to function. ...
Asked in Biochemistry
What characteristics of a protein remain after it is denatured?
When a protein is denatured, its molecular shape is altered. This alteration may or may not be reversible. What remains is the primary structure of the chain(s) of the protein, in other words the sequence of the amino acids. The tertiary structure referers to the overall three dimensional shape will be lost ...

What causes a protein to become denatured?
Proteins work best in a specific temperature, pH, and ionic conditions. The optimal conditions can differ depending on the protein involved, but they all have conditions that they work optimally in. If these conditions change just a little bit, it may just impair the function, but if the condition changes too much, the protein will be denatured (the 3-D structure is changed) and it will not work anymore. Once denatured, even if the optimal conditions are then given again, it still will...
When a protein is denatured why does it lose its functionality?
Protein functions are very dependent on shape! So if you permanently change its shape a lot ("denaturing") it will no longer work. Trying not to be technical ; for example, the substrate may no longer fit into the active sight. ...

What meats are recommended on a high protein diet?
High-protein diets have become a popular way to lose weight because emerging research has hinted that protein may be able to satisfy hunger High-protein diets have become a popular way to lose weight because emerging research has hinted that protein may be able to satisfy hunger ? ...

What could happen if an animal's enzymes overheat in a desert climate?
The enzymes will become denatured and not work. All metabolic processes would shut down. They may die. ...
Asked in Human Anatomy and Physiology
What effect might change in the pH of body fluids or body temperature that accompany illness have on enzymes?
Enzymes are proteins. Protein function is related to the 3-D structure of the protein, which may be affected by pH. Proteins are also buffers that maintain pH within a certain range, but when the limits of this range are exceeded, the protein is denatured and cannot function. ...

What is protein aggregation?
Aggregation is a general term that encompasses several types of interactions or characteristics. Aggregates of proteins may arise from several mechanisms and may be classified in numerous ways, including soluble/insoluble, covalent/noncovalent, reversible/irreversible, and native/denatured. ...

Why does not water denature protein?
water might, but it depends, are you talking purified normal pH water or something else? There are some enzymes whose normal function may be at very basic or acid pH, which might be denatured by neutral water. Your premise may not be accurate. ...

A denatured protein may re-form to its funtional shape when returned to its normal enviorntment What does that indicate about a protein's confirmation?
a denature protein may re-form to its functional shape when returned to its normal environment. what does that indicate about a protein's conformation? Proteins fold in natural environment (water) in a way that they are stable, but a non-polar solvent provides a very different environment, so the protein has to unfold and adopt a very different shape. ...
A protein catalyst used to speed up reactions?
Enzymes are biological catalysts made out of proteins. Proteins are coded for by deoxyribonucleic acid (DNA). Enzymes feature an active site where reactions are catalysed and may have other sites on the molecule where the combination of another chemical may activate or deactivate the enzyme. Enzymes have optimum conditions to work under for pH and temperature. Enzymes are normally denatured by heavy metals, high temperatures or extremes of pH beyond their optimum range. When an enzyme is denatured the physical structure of the...

Is denatured alcohol an alcohol?
It is a mixture of two alcohols: ethanol and methanol. <><><> The term Denatured refers to ethyl alcohol that has another substance mixed in that prevents it from being drunk. It may be methanol, unleaded gasoline, or amyl acetate. Denatured alcohol is poisonous to drink, and is used for industrial processes, ...
Asked in Chemistry
Is frying a hamburger a chemical or physical change?
Frying a hamburger represents a chemical change. The reason for this is that the heat alters the chemical nature of the meat, turning some of it into charred or denatured protein, etc. It it is heated to a high enough temperature, some of the ingredients in the meat may even turn into carbon dioxide and water, a combustion reaction of organic molecules. ...
Asked in Biology
What may cause a protein to be denatured?
The various proteins denature at different levels of the following factors. * Acidity - an acid or a base may denature an enzyme * Solvents - a solvent (a liquid or gas that dissolves solutes) may denature an enzyme. Specifically we would be looking at alcohols such as ethanol * Heat - such as the heat of a frypan that denatures the proteins of an egg ...

What is denaturing And what causes enzyme denaturing?
Enzymes are proteins that help speed up the the rate of chemical reactions in the human body. Enzymes possess a specific shape and this shape fits into the substrate. When an enzyme becomes denatured, it loses its shape and thus it cannot function effectively. Enzymes may become denatured due to high temperatures or changes in the pH. ...

How would you know if somethings a broken bone or sprain?
For a broken bone their will probably be a muscle splint. Where the muscles become very hard around where the break is. The broken bone may also colour the skin a sick/ill looking colour. ...
List four conditions under which proteins may be denatured?
Extreme heat, high or low pH, ionization of liquid medium, and a change in environment. The last one needs a little more explanation. If a protein is meant for a liquid-liquid environment, and it is brought into an air-liquid environment, it may denature. Proteins form because of the folds created from hydrophilic and hydrophobic folding. If there is no water in which these bonds form, the protein will denature. ...
Asked in Science
What happens to the enzyme when it is denatured?
An enzyme is a type of protein which means that it is made up of chains called polypeptides which are long chains of amino acids. The functional groups of the amino acids carry very specific magnetic charges so that they fold in a very precise way. A small change in some environmental factor such as a change in temperature or pH can change these charges slightly so that the protein looses its precise shape. This slight change in structure is known...
