pepsinogens การใช้

• Pepsin's gastric juice, pepsinogen activates to become pepsin.
• Pepsin cleaves the 44 amino acids from pepsinogen to create more pepsin.
• Pepsin in its secreted form is inactive ( pepsinogen ).
• Gastric juice in the stomach also contains pepsinogen.
• In the stomach, chief cells release pepsinogen.
• Enzymes like pepsin are created in the form of pepsinogen, an inactive zymogen.
• Another partially activated pepsinogen completes the activation by removing the peptide, turning the pepsinogen into pepsin.
• Another partially activated pepsinogen completes the activation by removing the peptide, turning the pepsinogen into pepsin.
• The low pH also activates the enzyme precursor pepsinogen into the active enzyme pepsin by self-cleavage.
• Pepsinogen is activated when chief cells release it into the gastric acid, whose hydrochloric acid partially activates it.
• The chief cells secrete pepsinogen in response to gastrin and especially Ach, and ACh also stimulates mucus secretion.
• The gastric chief cells of the stomach secrete enzymes for protein breakdown ( inactive pepsinogen, and in infancy rennin ).
• Achlorhydria may also be documented by measurements of extremely low levels of pepsinogen A ( PgA ) ( ) in blood serum.
• The hormone gastrin and the vagus nerve trigger the release of both pepsinogen and HCl from the stomach lining when food is ingested.
• The precursor of pepsin, pepsinogen, is secreted by the stomach, and is activated only in the acidic environment found in stomach.
• With an impulse from the vagus nerve, pepsinogen is secreted into the stomach, where it mixes with hydrochloric acid to form pepsin.
• The glandular portion produces hydrochloric acid and enzymes such as pepsinogen, as well as bicarbonate and mucus that helps prevent self-digestion.
• Hydrochloric acid activates pepsinogen into the enzyme pepsin, which then helps digestion by breaking the bonds linking amino acids, a process known as proteolysis.
• Histamine and gastrin act synergistically as the most important stimulators of hydrochloric acid secretion from parietal cells and stimulators of secretion of pepsinogen from chief cells.
• In addition, in the bat " Plecotus auritus ", fish and some amphibians, glands secreting pepsinogen or hydrochloric acid have been found.
