  2. Enteropeptidase - Wikipedia

    en.wikipedia.org/wiki/Enteropeptidase

    Enteropeptidase (also called enterokinase) is an enzyme produced by cells of the duodenum and is involved in digestion in humans and other animals. Enteropeptidase converts trypsinogen (a zymogen) into its active form trypsin, resulting in the subsequent activation of pancreatic digestive enzymes.

  3. Trypsin - Wikipedia

    en.wikipedia.org/wiki/Trypsin

    Trypsin digestion of extra cellular matrix is a common practice in cell culture. However, this enzymatic degradation of the cells can negatively effect cell viability and surface markers, especially in stem cells. There are gentler alternatives than trypsin such as Accutase which doesn't effect surface markers such as cd14, cd117, cd49f, cd292.

  4. Gastrointestinal physiology - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_physiology

    The digestive system has a complex system of motility and secretion regulation which is vital for proper function. This task is accomplished via a system of long reflexes from the central nervous system (CNS), short reflexes from the enteric nervous system (ENS) and reflexes from GI peptides working in harmony with each other.

  5. Digestive enzyme - Wikipedia

    en.wikipedia.org/wiki/Digestive_enzyme

    Digestive enzymes take part in the chemical process of digestion, which follows the mechanical process of digestion. Food consists of macromolecules of proteins, carbohydrates, and fats that need to be broken down chemically by digestive enzymes in the mouth , stomach , pancreas , and duodenum , before being able to be absorbed into the ...

  6. Human digestive system - Wikipedia

    en.wikipedia.org/wiki/Human_digestive_system

    There are several organs and other components involved in the digestion of food. The organs known as the accessory digestive organs are the liver, gall bladder and pancreas. Other components include the mouth, salivary glands, tongue, teeth and epiglottis. The largest structure of the digestive system is the gastrointestinal tract (GI tract).

  7. Pancreatic juice - Wikipedia

    en.wikipedia.org/wiki/Pancreatic_juice

    The pancreas is located in the visceral region, and is a major part of the digestive system required for proper digestion and subsequent assimilation of macronutrient substances required for living. Pancreatic juice is alkaline in nature due to the high concentration of bicarbonate ions. Bicarbonate is useful in neutralizing the acidic gastric ...

  8. Colipase - Wikipedia

    en.wikipedia.org/wiki/Colipase

    Intestinal bile acids (which aid lipid digestion by facilitating micelle formation) adhere to the surface of emulsified fat droplets, displacing lipase (which is only active at the water-fat interface) from the droplet surface. Colipase acts as a bridging molecule, binding to both lipase and bile acids, thus anchoring lipase onto the droplet ...

  9. Intracellular digestion - Wikipedia

    en.wikipedia.org/wiki/Intracellular_digestion

    Intracellular digestion is divided into heterophagic digestion and autophagic digestion. [3] These two types take place in the lysosome and they both have very specific functions. [3] Heterophagic intracellular digestion has an important job which is to break down all molecules that are brought into a cell by endocytosis. [3]
