Why are things like IgA, haptocorrin, intrinsic factor, mucin, gastrin, etc. discussed in an article about digestive enzymes? These are NOT digestive enzymes and serve only to confuse the naive reader about what digestive enzymes are. We already have an article about digestion and articles about individual organs to cover the other functions of the stuff digestive organs secrete. —Preceding unsigned comment added by 69.181.249.68 (talk) 06:28, 9 May 2011 (UTC)[reply]

is enzyme activity affected by temperature?
Yes, if the temperature increases, the rate of enzyme activity is higher. But if the temperature gets too high, the enzymes could denature.

Why are enzymes that are produced in the stomach, pancreus and ileum listed in this section? Pretty sure those are not in the oral cavity.

Finding fault with this sentence: "Enzymes are also in your mouth, helping to break down food, as well as the teeth are."

1) It is already clear that the enzymes are produced in the mouth. 2) The topic of the article is "Digestive enzyme", so while it is true that chewing with your teeth helps break down food, teeth are not an enzyme. 3) The sentence is just awkward. Looks like an afterthought and sounds like it was written by someone who speaks english as a second language. —Preceding unsigned comment added by 99.147.132.254 (talk) 22:13, 23 November 2008 (UTC)[reply]

Did you know that the digestion system has 4 different types of hormones? and; they are Insulin,PYY,Ghrelin,Leptin. —Preceding unsigned comment added by 74.255.60.71 (talk) 15:47, 20 March 2009 (UTC)[reply]

I really feel the use of words such as "your" is totally inappropriate for an encyclopedia. For example the first paragraph states: "Enzymes are also found in your saliva, which are made from your salivary glands." It reads like a letter to someone. A better waCy of writing that sentence would be: "Enzymes are also found in your the saliva, which are is produced from your within the salivary glands.

Further to this, the description of protons as 'positively charged hydrogen atoms' seems awful. An atom is by definition neutral - unsure of how to rephrase the sentence however. APL92 (talk) 19:19, 2 January 2011 (UTC)[reply]

what is the correct ph level needed for enzymes to function pH of 2. I added this statement in there. — Preceding unsigned comment added by Delbarbarawi (talk • contribs) 06:36, 8 September 2018 (UTC)[reply]

Chymotrypsinogen, which is a inactive(zymogenic) protease that once activated by duodenal enterokinase, breaks down proteins at their aromatic amino acids. Chymotrypsiongen can also be activated by trypsinogen. Edited the final word to trypsin, as makes more sense, and as it says in the chymotrpsinogen article.

This page is a magnet for occasional vandalism and deletions as you can see in the history. Can this page be protected? Dr. Persi (talk) 04:26, 16 February 2011 (UTC)[reply]

Many of the molecules listed in the article are by definition not enzymes. Many of those listed are protein hormones and non-protein chemicals which are not enzymes. Is the best solution to go through and delete all entries which are not actually enzymes? Lost of this is useful but it's very misleading the way it is. Because of these errors this is one of the worst Wiki articles I have seen in years. Earthdirt (talk) 14:15, 22 March 2012 (UTC)[reply]

I notice that there is nothing in this article about why some people believe digestive enzymes need to be supplemented. Could someone address this please. Is it a matter of losing the ability to create some enzymes with age? Are they damaged by toxins? — Preceding unsigned comment added by 69.114.111.168 (talk) 20:22, 10 November 2012 (UTC)[reply]

Companies now market Digestive Enzyme supplements. Where would these be covered in WP ? ( Exocrine pancreatic insufficiency doesn't say much.) How effective are they ? - Rod57 (talk) 15:48, 9 March 2016 (UTC)[reply]
