carbohydrate digesting enzymes have an optimum pH near neutrality so is for carbohydrate digestion.
Pepsin is therefore acidic since the pH in the stomach is 2
The optimum pH is 8.8
The optimum pH is neutral, 7.
The optimum pH of lactase is pH = 6.5.
The temperature optimum can be affected by pH if the pH chosen for a particular experiment deviates from the pH optimum for invertase
Bertram Metherel Shelton has written: 'Determination of the optimum pH for the tryptic digestion of gliadin and globin'
Well without specifying the parameters its impossible to say; the definition of optimum pH would be, the pH at which point the optimum results of a reaction are achieved.
pH optimum: 7.8 (pH 6.0: about 35% of maximal activity, pH 9.3: 40% of maximal activity)
optimum pH of amylase from sweet potato is about 6.0
Carbohydrate digestion starts in the mouth, and later is further digested in the small intestine.
carbohydrate digestion doesn't occur in the stomach and the large intestine.
the hydrochloric acid is likely to prevent the digestion of starch by carbohydrase enzymes in the stomache because the carbohydrase enzymes optimum PH is PH7. The Hydrochloric acid in the stomache makes the PH in the stomache PH3 therefore the stomache has too weak a PH for the enzymes to be able to work.
