The effects of condiment (salt) and processing technic (homogenization) on digestion and interfacial properties of micro/nano-sized colloidal particles (MNCPs) in bigeye tuna head soup (BTHS) using simulated gastrointestinal digestion model in vitro were investigated. For MNCPs in BTHS, the triglycerides
The aim of this work was to investigate the effects of high-intensity ultrasound (sonication), on the structure and allergenicity of the major cow's milk allergen, beta-lactoglobulin (BLG). Structural changes upon sonication of BLG were monitored by circular dichroism spectroscopy, tryptophan
Gastric proteinases--structure, function, evolution and mechanism of action.
Gastro-oesophageal reflux disease is defined as the presence of symptoms or lesions that can be attributed to the reflux of gastric contents into the oesophagus. Aspiration and prolonged monitoring studies in humans have shown that reflux of gastric contents is

Multidomain protein folding is often more complex than a two-state process, which leads to the spontaneous folding of the native state. Pepsin, a zymogen-derived enzyme, without its prosegment (PS), is irreversibly denatured and folds to a thermodynamically stable, non-native conformation
