It is about pH 1 to 2. The gastric acid in our stomach (mainly consisting of hydrochloric acid, HCl) is at this pH level. The acidic medium is necessary for the digestive enzymes, such as those involved in the digestion of proteins, in gastric juice to work.
The optimal pH level of the stomach for proper digestion is around 1.5 to 3.5.
The optimum PH of pepsin ranges between 1.0 and 4.0. Pepsin exhibits about 90 percent of the maximum activity and about 35% of the maximum activity.
Actually the pH of the stomach very acid relative to pH 7 (between pH 1-4). An acidic stomach is optimal for the breaking of hydrogen bonds that makes up the complex compounds in the food we ingest, like proteins. The acidity of the stomach is generated by the excretion of hydrochloric acid (HCl) which combines with pepsinogen to create pepsin into the stomach, which is a strong acid.
pepsin is activated from pepsinogen in stomach. the pH range for its optimal ativity is at acidic pH between 1.5 to 2. It is also stable upto pH8 and can be inactivated at basic pH from 8.5,
The optimal pH for pepsin, an enzyme found in the stomach that helps in protein digestion, is around 2.0. This low pH is necessary for pepsin to be active and function effectively in breaking down proteins into smaller peptides.
pepsin is found in the stomach and the pH there is 2 while trypsin is found in the small intestine (duodenum and jejunum) and the pH there is 8-9. Thus, the optimum pH levels for pepsin and trypsin are 2 and 8-9 respectively.
The optimal pH depends on what you are growing. Much like soil pH, it will need to be adjusted per crop.
Enzymes are active in the stomach, which has an acidic pH between 1.5 and 3.5. At this pH, pepsin is an enzyme that digests proteins. Enzymes in the body typically have optimal pH ranges where they are most active.
Basic. Trypsins have an optimal operating pH of about 8(and optimal operating temperature of about 37°C)
The stomach contains hydrochloric acid, which has a pH of generally 1-3. These optimal pH levels must be present in order for pepsin (a protein-digesting enzyme) to function. If the pH is not acidic, pepsin will only be present in its inactive form, pepsinogen, and protein digestion will effectively occur. Uhh.. hope that's what you were looking for. The second part is just a bit more detail as to why the pH of stomach is important.
Most human enzymes work at a optimal pH of 7.4, but other enzymes work at many different pH ranges, for example Pepsin works best at an optimal pH of 2.6 and Trypsin works best at an optimal pH of 7.8.
Your stomach acid has a pH of 1.5 to 3.5
