Why do proteins become polyanions at very high pH?
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.
PH of washing powder?
The pH of washing powder is usually around 10-11, which is alkaline. This high pH level helps to remove dirt and stains effectively from clothes by breaking down oils and proteins. However, it is important to ensure that the pH is not too high, as it can damage certain fabrics and irritate the skin.
How can you figure out what is making your pools pH balance high?
The pH of your pool should be ideally 7.4. this will change if you add chlorine as this will have the effect of raising pH which is why you need to control the pH with an Acid such as sodium bisulphate or marked up as pH minus (pH-) . Also when you add any water from the tap if the pH of incoming water is high then this will also change the pH. Watch out for low Total Alkalinity as this can cause pH bounce where you get fluctuating pH readings.
What is the pH of depilatory cream?
The pH of depilatory cream can vary depending on the specific brand and formulation. However, most depilatory creams have a pH around 9-10, which is alkaline in nature. This high pH helps to break down the hair proteins for effective hair removal.
How would a high-protein diet affect the pH of the urine?
A high-protein diet can increase the acidity of urine due to the metabolism of proteins, which results in the production of acidic byproducts like sulfuric acid and phosphoric acid. This can lower the pH of urine and make it more acidic.
How does a large change in temperature or PH effect proteins?
It denatures it.
How does heat effect pH level?
Heating pure water the pH decrease.
What effect the pH have on protein digestion with pepsin?
It is most effective at around pH 2, and becomes inactive over 5.
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 a high pH level effectively kill bacteria?
Yes, a high pH level can effectively kill bacteria by disrupting their cell membranes and denaturing their proteins.
What may cause a protein to 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.
What happens to pH when chlorine level is high?
Since most types of chlorine are very high in PH it may effect the over all PH of the water if it is not buffered.
In an experiment to study the effect of proteases on proteins what is the most likely effect of a major change in pH?
A major change in pH can denature proteins by disrupting their structure, leading to loss of function. Proteases may become more or less active depending on the specific pH change, potentially affecting their ability to break down proteins. Overall, extreme pH changes can alter the experimental outcome by impacting protein stability and protease activity.
When the pH if body fluids begins to fall proteins begin to?
When the intra and extra-cellular fluids become very acidic, proteins will not be broken down, because an acidosis bring the pH down, usually, no more than 1 pH. Therefore, that does not effect proteins much.
What is heat shocked protein?
I guess a heat-shocked protein would be a denatured protein. Proteins and enzymes function under certain conditions, like pH and temperature. When the temperature gets too high, the protein unfolds itself, or denatures. When it gets back to normal conditions, it will just re-fold right back like it was before.
