A change in PH can alter the 3D confirmation of the protein cauzing it to lose function partially or completely.
**** A change in pH can denature a protein and also can cause it to change shape, therefore making it useless****

∙ 10y agoThey begin to "denature" or decompose to a certain extent. This breaking down of the protein structure cause it to lose shape. It also restricts it from functioning properly and often interferes with other protein processes.

∙ 14y agoDepending on the type of protein, some proteins become denatured when exposed to harsh PH levels, such as high or low. Once the protein is denatured it will no longer be able to perform its task as well, if at all.
Hope this helped :)

∙ 13y agoA drastic change in pH, temperature, or salt concentration can change the tertiary level, which leads to the denaturing of the protein. Sometimes, when the pH, temperature, or salt concentration is restored, the protein can renature, but doesn't always happen. This is one of the reason why dwelling in an area with extreme temperature can be harmful.

∙ 11y agoAt low but non-freezing temperatures, proteins become more stable. Less thermal energy in the system means that the proteins spatial fluctuations will decrease. However, this often results in decreased activity of the protein.
At freezing temperatures, proteins generally lose their native conformation as they interact with rigid ice crystals.

Symptoms of phenylketonuria PKU may be minimized or suppressed by a diet low in?
a diet low in protein will help with the symptoms. protein contains phenylalanine, which is what a person with PKU cannot absorb. by cutting out the phenylalanine (phe), you eliminate the problem. most with PKU can only eat enough protein for proper development. other than that, nothing high in protein. i.e. fish, eggs, milk, etc.
What happens in an acidic solution?
Acidic solution have high concentration of dissociable H+ ions and have low pH.

It depends on the type of structure; simple covalent structures (like water) generally have low boiling points, while giant covalent structures (like diamond) have high boiling points.

What is it called when an enzymes active site loses its shape?
When this happens to a protein, it is said to denature.Denature is caused commonly by very high or low temperature,concentrated acids or bases.Denature by high temperature is irrevesible.
