Chronic backflow of pepsin, acid, and other substances from the stomach into the esophagus, is the basis of reflux conditions, particularly gastroesophageal reflux disease (GERD) and laryngopharyngeal reflux. In the latter, pepsin and acid travel all the way up to the larynx, where they can lead to damage of the laryngeal mucosa and lead to symptoms ranging from hoarseness of the voice and chronic cough to laryngospasm (involuntary contraction of the vocal cords) as well as laryngeal cancer L2358.
Though limited data is available on the toxicity of exogenous pepsin (not naturally produced in one's gastrointestinal tract), it can be extrapolated from the above-mentioned information that pepsin overdose may lead to mucosal tissue damage of the gastrointestinal tract.
Pepsin is a potent enzyme in gastric juice that digests proteins such as those in meat, eggs, seeds, and dairy products L2358.
Studies on gastric digestion from 1820-1840 led to the discovery of pepsin as the substance which, in the presence of stomach acid, causes nutrients including meat or coagulated egg whites to dissolve. Soon afterward, it was shown that these protein nutrients were cleaved by pepsin to products called peptones A32603.
Pepsin is often used as a replacement enzyme for those with pancreatic insufficiency L2357. Stimulation of the pancreas and therefore enzymatic digestion of food is a tightly controlled and is a hormonally mediated process. Any changes or conditions affecting metabolic steps for successful digestion and absorption negatively affect pancreatic enzymatic secretion, entry into the intestine, functionality once inside the intestine, and appropriate mixing with foods/nutrients. Many causes of pancreatic insufficiency require that enzyme replacement therapy is started, including cystic fibrosis, pancreatic cancer, acute and chronic pancreatitis, as well as pancreatic surgery L2357.
Pepsin is approved by the FDA and is used in food at levels not to exceed current good manufacturing practice L2363.
Interestingly, it has been used as a marker for laryngopharyngeal reflux (LPR), which is a common illness of otolaryngology (ear, nose and throat specialist) visits A32604.
Interestingly, recent research has suggested that pepsin participates in the digestion of nucleic acids L2391.
Fitur visualisasi ini dikembangkan menggunakan pendekatan Graph Theory untuk memetakan hubungan polifarmasi dan molekuler. Entitas (Obat, Target, Gen) direpresentasikan sebagai Simpul (Nodes), sedangkan hubungan biologisnya sebagai Sisi (Edges).
drugbank-id dan name pada skema XML DrugBank.targets/target yang memuat polipeptida sasaran.gene-name dan varian snp-effects.Tata letak grafik menggunakan algoritma Force-Directed Graph (Barnes-Hut). Model fisika ini menerapkan gaya tolak-menolak antar simpul (Gravitasi: -3000) agar tidak tumpang tindih, serta gaya pegas (Spring: 0.04) pada garis penghubung untuk fleksibilitas interaksi.
