Proteins have many ionizable groups like carboxyl (COO-) and amino (NH3+) groups. At very high pH, these groups lose or gain protons, resulting in a net negative charge on the protein, turning it into a polyanion. The pH conditions promote deprotonation of the acidic sites on the protein, leading to an increase in negative charges.

What class of organic molecules is damaged by high temperature?
Enzymes are proteins. They are very important because they catalyse metabolic processes in the body that would not be able to occur without them. Their function is dependant upon their shape. If an enzyme is not the correct shape for the molecules it need to bind to then it will not be able to catalyse the process it is involved in. The shapes (quaternery structure) of enzymes are the result of attractive forces between funtional groups within the protein. These attrative forces are quite weak, and high temperatures within the body will break them and the enzymes will lose their shape (they are de-natured). Once the structure is lost it cannot be reformed again, so the process regulated by any enzyme that has denatured no longer function properly.
What is the chemical equation for proteins?
Proteins have a very complicate chemical formula but not a "balanced chemical equation".
Why does the throughput drop when is load is either very low or very high?
The sent packets will increase according to the sent packets. And the relationship will become less. When it is over 1100 the number of received packets will decrease when the sent packets keep increasing.
Like atoms can molecules can become ions true or false?
Some molecules can become ions, especially at very high temperatures or at other high-energy conditions. For example, a hydrogen molecule can become a positive ion by losing one of its electrons.
What are the drawbacks of sds page?
Some drawbacks of SDS page include: Limited resolving power for proteins with similar sizes. Inability to provide information on protein structure or function. Difficulty in separating proteins with very high or low molecular weights. Potential loss of biological activity during sample preparation.
Why is it important not to heat the food substance which is being tested for protein?
Heating the food substance being tested for protein can denature the proteins, leading to false results in the analysis. This can affect the accuracy of protein content measurements and skew the nutritional information of the food product.
Can aluminum become a gas?
Yes only if it is melted at a VERY high temp
Can a virgin become an escort?
Yes, but it is probably a very bad idea. Escort is a very high risk profession.
Market failure occurs when?
Prices of essential goods such as gas has become very high.
Is proteins a element?
Proteins are not elements; they are very complex organic compounds.
Why are digestive enzymes secreted into small intestine rather than in stomach?
because stomach has very high acid... so it will just denature the proteins.
Are snow crab legs a high cholesterol food?
Snow crab legs are not high in cholesterol. When you dip them in butter, they become very high in fat and cholesterol.
Academic skills to become an obstetrician?
A high IQ, combined with very strong study habits.
Can you live with a dead fetus in you?
There is a very high risk that the dead fetal tissue will become infected.
Is pork high on protein?
Here is a list I found on about.com . http://lowcarbdiets.about.com/od/whattoeat/a/highproteinfood.htm
What is made when stars die?
There are three types of stellar remnants. Low to medium mass stars will become white dwarfs. High mass stars will become neutron stars. Very high mass stars will become black holes.
Why do people choose one dish meals?
because it is convenient to eat and attractive. it is high in lots vitamins, proteins, carbohydrates and fats(very little). in other words, its very healthier and easier to cook...
