Anti-pepsin activity of silicon dioxide nanoparticles [PDF]

Revista Colombiana de Química, 2016
SiO2NPs as an inhibitor of pepsin enzyme for treatment of gastro-esophageal reflux disease (GERD) was used. Silicon dioxide nanoparticles (pepsin coated SiO2NPs) are among the safest nanoparticles that can be used inside the human body.

Cleavage Reaction Lateral Flow Assays for Salivary Pepsin Measurement Using a Pepsin-Susceptible Peptide Substrate

Chemosensors
In this study, we introduce a novel cleavage reaction lateral flow assay (LFA) based on pepsin activity against a pepsin-susceptible peptide (PSP) substrate to detect salivary pepsin.

Separation of pepsin I, pepsin II A, pepsin II B, and pepsin III from human gastric mucosa [PDF]

American Journal of Physiology-Legacy Content, 1963
Extracts of human gastric mucosa have been fractionated on diethylaminoethyl cellulose to yield three precursors of proteolytic enzymes active at low pH which have been called pepsinogen I, pepsinogen II, and pepsinogen III. Pepsinogen I has been found in the mucosa from all parts of the stomach examined as well as in the proximal duodenum. Pepsinogen

Pepsin D. A minor component of commercial pepsin preparations [PDF]

Biochemical Journal, 1967
Methods are described for the isolation and purification of pepsin D, an enzyme which accounts for about 10% of the enzymic activity in commercial preparations of pepsin. Pepsin D is similar to pepsin in having a molecular weight of about 35000, the same C-terminal amino acid sequence, and an N-terminal isoleucine residue.

Nasal pepsin A

International journal of health sciences, 2022
Laryngopharyngeal reflux (LPR) can contribute to chronic rhinosinusitis (CRS). Pepsin is believed to be one of the causes of CRS. Pepsin can be a promising biomarker because it is only produced by gastric parietal cells, so it can explain the correlation of CRS with LPR.

Antibacterial activity of a pepsin‐derived bovine hemoglobin fragment [PDF]

FEBS Letters, 2001
Peptic digestion of bovine hemoglobin yields a fragment with antibacterial activity. This peptide was purified to homogeneity by a two‐step procedure including anion exchange chromatography and preparative reversed‐phase HPLC. Mass determination and fragmentation indicated that this peptide corresponded to the 1–23 fragment of the α chain of hemoglobin.

Kinetics of pepsin-induced hydrolysis and the coagulation of milk proteins

Journal of Dairy Science, 2022
: Hydrolysis-induced coagulation of casein micelles by pepsin occurs during the digestion of milk. In this study, the effect of pH (6.7–5.3) and pepsin concentration (0.110–2.75 U/mL) on the hydrolysis of κ-casein and the coagulation of the casein ...

High Ionic Strength Enhances the Anti-Pepsin Activity of Titanium Dioxide Nanoparticles

Nano Biomedicine and Engineering, 2016
Gastro-esophageal reflux disease (GERD) is a state that evolves when there is a return of acid and pepsin enzyme into the esophagus. Inhibition of pepsin enzyme is one of the strategies used successfully for the treatment of GERD.

Immobilization of Pepsin onto Chitosan Silica Nanobeads with Glutaraldehyde as Crosslink Agent

Bulletin of Chemical Reaction Engineering & Catalysis, 2014
Glutaraldehyde crosslinked chitosan - silica nanobeads have been used as a support in the immobiliza-tion process of pepsin. The effect of pH, pepsin concentration, and temperature on the characteristics of both free and immobilized pepsin had been ...
