A protein consists of amino acids. Some of these amino acids are polar, having positively charged sides and negatively charged sides. A change in PH simply means a change in the amount of (H+) atoms. As you can see these hydrogen atoms are positively charged, and attract the negative side of the polar amino acids. so a change in the PH changes the stability of a protein structure and can cause its denaturation.

What organs aid in the chemical breakdown of proteins?
Stomach - highly acidic environment will denature and/or break down proteins.
Why are high temperatures not suitable for anaerobic fermentation?
Temperatures in excess of 40oC will denature the enzymes (proteins) in the yeast, which makes them inactive.
What two factors can cause denaturing of an enzyme?
Temperature and enzymes. A good temperature example is the proteins in egg whites denaturing when exposed to heat. Specific enzymes denature specific proteins: lactase (an enzyme) denatures lactose (protein present in dairy products). Protein denaturation can be caused by a number of different factors. These include heat exposure, introduction to acidic surroundings, and exposure to high energy electromagnetic radiation.
Does temperature affect a proteins shape?
It absolutely does. All proteins have optimum temperatures at which they are able to operate. Temperatures unsuitable for the proteins may cause it to denature into smaller peptides, or simply change shape due to the alteration of bond energies, resulting in broken or reformed bonds elsewhere in the amino chain.
How does heat denature enzymes?
Many things can denature proteins. Proteins have different optimal ranges in pH and temperature and outside of these optima then the enzyme will not work as well or at all. Also specific detergents will denature an enzyme depending on the enzyme.
Which material can not denature Proteins?
Freezing
What are four substances that can denature proteins?
maltase
Does boiling denature cells?
Boiling can allow for the extraction of DNA.
What chemicals denature proteins?
Denaturants such as urea, SDS, guanidium hydrochloridecan denature proteins. Organic solvent such as alcohol can be also used to denature proteins. A combination of reducing agent DTTor beta-mercaptoethaol with heating at 90 degrees for 5 minutes about will completely kill the three dimensional structure of proetin and make it to its primary structure.
Why is it important that proteins exist in a stable environment?
otherwise they would denature
What organs aid in the chemical breakdown of proteins?
Stomach - highly acidic environment will denature and/or break down proteins.
Why does the body produce hydrochloric acid?
to digest (denature) proteins - its stomach acid.
Does proteolytic enzymes cause denature of proteins?
Denaturing in the sense that proteolytic enzymes reduce proteins to their amino acid subunits.
What if your blood pH was 8.1?
You would die. The blood proteins would denature and stop functioning.
What do high temperatures do to lactobacillus casei?
It will bake the culture, and denature the proteins in the bacteria, turning them hard.
What make proteins like enzymes unwind when placed in extreme pH or temperature conditions?
Denature
Why doesn't cold temperature denature protein?
It depends on how low the temperature is. For the vast majority of proteins, low temperatures will actually stabilize them (so long as it is above 0 oC). If the temperature gets below 0 oC the protein may denature. Although in most cases, the temperature has to be far below 0.
