What Causes Stomach Discomfort? Treatments and Remedies for Lactose Intolerance. Digestion of proteins in the stomach is helped by stomach acid , which is strong hydrochloric acid. This also kills harmful microorganisms that may be in the food. Lipase enzymes break down fat into fatty acids and glycerol. Digestion of fat in the small intestine is helped by bile , made in the liver. Bile breaks the fat into small droplets that are easier for the lipase enzymes to work on.

Bile is not an enzyme. Dietary enzymes are available in pill form as supplements. Likewise, it may have ingredients not listed on the label. Heating foods can destroy any naturally occurring enzymes in them. Some people may have stomach irritation or other unpleasant gastrointestinal side effects with enzyme supplements.

Be sure to talk with your doctor about any potential risks or complications with dietary enzymes. Enzymes are crucial for good health. Your body produces them. You can also get them in fruits, vegetables, and other foods. They can affect your metabolism in negative ways. Changes in the color and consistency of your stool may indicate nutritional deficiencies. Taking dietary enzymes can make a positive impact on your health, but only if you really need them.

Pancreatitis is inflammation of the pancreas and causes abdominal tenderness and pain. Learn more. Blood tests can help determine the cause of severe abdominal pain. Checking amylase and lipase levels can help determine if you have pancreatitis. At-home microbiome testing kits can be a first step. We look at these and give our recommendations for your overall gut health questions. Cholangitis is inflammation swelling in the bile duct.

Treatment depends on your symptoms and whether you have chronic or acute cholangitis. Gastroparesis is a condition in which your stomach empties into your small intestine too slowly.

Learn about the best diet for gastroparesis and what…. What does a gastroenterologist do, and when should you see one? Here's what you should know before making an appointment. Further breakdown of peptides to single amino acids is aided by enzymes called peptidases those that break down peptides. Specifically, carboxypeptidase, dipeptidase , and aminopeptidase play important roles in reducing the peptides to free amino acids.

The amino acids are absorbed into the bloodstream through the small intestines. The steps in protein digestion are summarized in Figure Lipid digestion begins in the stomach with the aid of lingual lipase and gastric lipase. However, the bulk of lipid digestion occurs in the small intestine due to pancreatic lipase.

When chyme enters the duodenum, the hormonal responses trigger the release of bile, which is produced in the liver and stored in the gallbladder. Bile aids in the digestion of lipids, primarily triglycerides by emulsification. Emulsification is a process in which large lipid globules are broken down into several small lipid globules.

These small globules are more widely distributed in the chyme rather than forming large aggregates. Lipids are hydrophobic substances: in the presence of water, they will aggregate to form globules to minimize exposure to water.

Bile contains bile salts, which are amphipathic, meaning they contain hydrophobic and hydrophilic parts. Thus, the bile salts hydrophilic side can interface with water on one side and the hydrophobic side interfaces with lipids on the other. By doing so, bile salts emulsify large lipid globules into small lipid globules.

Why is emulsification important for digestion of lipids? Pancreatic juices contain enzymes called lipases enzymes that break down lipids. If the lipid in the chyme aggregates into large globules, very little surface area of the lipids is available for the lipases to act on, leaving lipid digestion incomplete.

By forming an emulsion, bile salts increase the available surface area of the lipids many fold. The pancreatic lipases can then act on the lipids more efficiently and digest them, as detailed in Figure Lipases break down the lipids into fatty acids and glycerides. These molecules can pass through the plasma membrane of the cell and enter the epithelial cells of the intestinal lining.

The bile salts surround long-chain fatty acids and monoglycerides forming tiny spheres called micelles. The micelles move into the brush border of the small intestine absorptive cells where the long-chain fatty acids and monoglycerides diffuse out of the micelles into the absorptive cells leaving the micelles behind in the chyme. The long-chain fatty acids and monoglycerides recombine in the absorptive cells to form triglycerides, which aggregate into globules and become coated with proteins.

These large spheres are called chylomicrons. Chylomicrons contain triglycerides, cholesterol, and other lipids and have proteins on their surface. Together, they enable the chylomicron to move in an aqueous environment without exposing the lipids to water.

Chylomicrons leave the absorptive cells via exocytosis.
