Pepsinogen is the proenzyme of pepsin.

Pepsinogen is inactive, it is metabolized into the enzyme pepsin which break down proteins into small molecules.

Is it safe to eat 50 eggs in one sitting?

My friend ate 55 eggs in a college competition. He was fine afterwards and was in good spirits generaly until the next day. But then after digestion the protein fom the eggs gathered around a part of his brain and formed basically a protein mass that starved part of his brain of oxegen.

He spent 4 weeks in a coma, believe it or not, and when he came out of hospital he was just a shadow of the person he was - drooling and stuff and pretty much babling and ranting on about anything and everything, talking non stop and generally being a bore.

Haven't heard from him in a while but last thing I heard he was a member of parliament in the UK.

What is the wildest division of the large intestine?

The small intestine (or small bowel) is the part of the GI tract following the stomach and followed by the large intestine, and is where much of the digestion and absorption of food takes place. The small intestine is composed of a duodenum, jejunum, andileum. It receives bile juice and pancreatic juice through the pancreatic duct, controlled by the sphincter of Oddi.

This article is primarily about the human gastrointestinal tract. The information about its processes is directly applicable to most placental mammals. The primary function of the small intestine is the absorption of nutrients and minerals found in food.[2] A major exception to this is cows; for information about digestion in cows and other similar mammals, see ruminants. In invertebrates such as worms, the terms "gastrointestinal tract" and "large intestine" are often used to describe the entire intestine.

What is the function of the gastric canal?

the gastric canal has an important clinical role in the stomach as it allows for gastic juices to be removed before absorption

Is there ammonia in your friend's body?

Yes there is ammonia in human body. Most of the ammonia in body is obtained during digestion in the intestine. The bacteria break down proteins in food to form ammonia. Liver converts ammonia into urea which you urinate out.

What ice cream ingredients get digested in the mouth?

well if you think about it your body temperature is higher than the temperature of ice cream therefore it will melt in your mouth and become a thick liquid. I would look at the reactions of the mouth acids to the ingredients in the ice cream as different flavours or added bits can be different. but in msn it was said the ice was in the top ten for hardest food to be digested. If that helps what so ever

What do you think will happen if enzymes are not present during digestion?

Without digestive enzymes the digestion would be a serious trouble.5_ways_to_improve_your_digestion:

Basic 1) chew, chew, chew.

  • Put your fork down in between bites.
  • Try using chopsticks - it forces you to slow down.
  • Thoroughly chew each bite of food.
  • Carbohydrate digestion begins in the mouth - chewing grains thoroughly allows amylase, the digestive enzyme present in saliva, to digest the grains.

Basic 2: Get Enough Water

Insufficient water intake is a primary cause of constipation. Constipation then causes an imbalance in bacteria, promotes inflammation of the intestinal lining, and can even lead to the absorption of larger molecules, a condition known as intestinal permeability. 5 Ways to Boost Your Water Intake.

Basic 3: Increase Your Dietary Fiber

Good sources of dietary fiber include:

  • Dried fruit, such as dates, figs, and prunes
  • Beans and legumes- if you don't have time to cook dried beans, buy canned, but make sure you rinse them thoroughly before cooking. Lentils and split peas are less gas-forming than other legumes.
  • Bring an apple with you to work as a snack
  • Ground flaxseeds are a gentle laxative. They can be useful for chronic constipation, damage to the intestine wall from laxative use, irritable bowel, and to soothe inflammation. Sprinkle ground flaxseeds on rice, grains, salads, or any other meal of your choice.
  • Oat bran everyday.
Practice Mindful EatingA pilot study at Indiana State University found that mindfulness, including specific instructions to slowly savor the flavor of food and be aware of how much food is enough, helped to reduce eating binges from an average of four binges per week to one and a half. Enzymes and DigestionDigestion begins in the mouth where we physically break down foods with our tongue and teeth. The food particles then travel to the stomach where they are further digested by the acidic stomach juices.

As food leaves the stomach and enters the small intestine, several digestive fluids are added. These fluids contain enzymes, which aid in the digestive process. For example, the pancreas secretes three enzymes into the small intestine: amylase, protease, and lipase. These enzymes are also produced by the intestinal wall.

Enzymes in FoodWe also get important enzymes from the foods we eat. However modern cooking practices and food processing kills many of these enzymes before we ingest them. This lowers the amount of enzymes in our digestive system and slows the digestive process. Enzyme SupplementsTherefore, many people take supplements that contain plant enzymes that catalyze, or stimulate, the digestion process.

These supplements often contain amylase, protease and lipase - enzymes that help take some of the work away from organs like the pancreas, which may be under undue stress due to modern eating habits.

Digestive Enzymes: AmylaseEach of these enzymes have special binding spots called receptors that help it match with and bind to a particular type of nutrient. For example, amylase digests carbohydrates such as the starches found in potatoes and pasta. Digestive Enzymes: ProteasesProteases help the body break down protein found in foods such as meat into tiny building blocks that can then be used to build and maintain the body's tissues. Digestive Enzymes: LipasesAnd lipases help the body break down fats and oils, which may help lower the amount of fats circulating in your blood stream.
