Abstract:
The exosecretes of the digestive glands contain two pools of hydrolytic enzymes - newly formed in the secretory cycle of glandulocytes and recreted from blood flowing to the glands. The second pool of enzymes is repeated many times due to the incretor transport and resorption of hydrolases and zymogens from the secretions of the ductal system of the glands and the chyme of the gastrointestinal tract into the composition of the interstitial fluid and the lymph formed by it. These processes ensure the recycling of digestive gland enzymes, reusable delivery of hydrolases and their inclusion in th

Abstract:
Supramaximal stimulation of the pancreas with the CCK analog caerulein causes acute edematous pancreatitis. In this model, active trypsin can be detected in the pancreas shortly after the start of supramaximal stimulation. Incubation of pancreatic acini in vitro with a supramaximally stimulating caerulein concentration also results in rapid activation of trypsinogen. In the current study, we have used the techniques of subcellular fractionation and both light and electron microscopy immunolocalization to identify the site of trypsinogen activation and the subsequent fate of trypsin during caer

AbstractIn vertebrates and invertebrates, morphological and functional features of gastrointestinal (GI) tracts generally reflect food chemistry, such as content of carbohydrates, proteins, fats, and material(s) refractory to rapid digestion (e.g., cellulose). The expression of digestive enzymes and nutrient transporters approximately matches the dietary load of their respective substrates, with relatively modest excess capacity. Mechanisms explaining differences in hydrolase activity between populations and species include gene copy number variations and single‐nucleotide polymorphisms. Trans

Abstract:
This type of digestion is characterized by the fact that enzymes synthesized by secretory cells are released into the extracellular environment, where their hydrolytic effect is realized. The secretion of hydrolytic enzymes from cells into the digestive cavities first appeared in coelenterates and ctenophores. In annelids, crustaceans, insects, cephalopods, tunicates, and chordates (with the exception of the lancelet), extracellular digestion predominates. It is especially developed in highly organized animals and humans, in which it provides the initial digestion of nutrients. In these organi

Carbohydrates (e.g., starch and cellulose) are the main energy source in the diets of dairy cows. The ruminal digestion of starch and cellulose is achieved by microorganisms and digestive enzymes. In order to improve their digestibility, the microbes and enzymes involved in starch and cellulose degradation should be identified and their role(s) and activity known.

Acute pancreatitis is characterized by hyperamylasemia, pancreatic edema, and the presence of activated digestive enzymes within the pancreas. The secretagogue-induced model of acute pancreatitis is also characterized by pancreatic acinar cell vacuolation, subcellular redistribution of lysosomal hydrolases, and a fall in pancreatic glutathione levels. We have performed time-dependence studies to determine the sequence with which these phenomena appear and to establish their cause-and-effect relationship.

Abstract:
Although carbohydrates are a principal component of the human diet, the mechanism of the final stages of starch digestion is not fully understood. One approach to treating metabolic diseases such as type II diabetes, obesity, and congenital sucrase isomaltase deficiency is inhibition of intestinal α-glucosidases and pancreatic α-amylases. Intestinal α-glucosidases, sucrase isomaltase (SI) and maltase glucoamylase (MGAM), are responsible for the final step of starch hydrolysis in mammals: the release of free glucose.

Abstract:
Serine proteases are considered the main class of protein digestive enzymes present in the midgut of many lepidopteran species and are the focus of the review in this chapter. Among them, trypsin and chymotrypsin are the most studied and participate in a great diversity of physiological processes that include, in addition to digestion, activation of specific proteins, such as in the coagulation cascades, in the immune system of insects and plants, in the development and production of biologically active peptides, in signal transduction, hormone activation, and development. In this chapter, a review was made of the structural characteristics of trypsins, specifically of Lepidoptera insects, main experimental and theoretical techniques for the study of their function and structure, and interaction with other proteins and ligands as protease inhibitors. Finally, it was described how this type of hydrolases can be a focus of inhibition in pests to the detriment of the development and death of the target insect. Until now, the main strategies of agricultural crop management, especially of large crops, consist of the use of inorganic pesticides and transgenic cultivars containing Bacillus thuringiensis toxins. Therefore, new and ecologically friendly strategies are necessary, such as the use of protease inhibitors.

Abstract:
In the context of the escalating global obesity crisis, this chapter delves into innovative strategies for combating excessive weight gain, focusing on the pivotal role of pancreatic lipase inhibition. The prevalence of obesity has reached alarming levels, causing severe health issues and over 2.6 million annual deaths. Existing anti-obesity drugs, such as orlistat, can cause undesirable side effects, thereby requiring the exploration of alternative lipase inhibitors with low to no side effects. This study comprehensively examines microbial, fungal, marine, and plant-derived inhibitors, spotlighting resin glycosides derived from morning glory vegetables as a promising source. Structural elucidation of various resin glycosides and their amphipathic nature and inhibitory potential against pancreatic lipase are explored. This study further extends to investigate flavone oligomers as potential starch hydrolase inhibitors for diabetic control, presenting the structural diversity and inhibitory activities of an array of biflavonoids. A comprehensive understanding of these natural compounds provides a foundation for developing alternative and effective therapies for obesity and diabetes, steering toward a healthier global population.
