WebBackground & Aims: The lipolytic potential of digestive lipases in vivo has always been deduced so far from their in vitro activities under nonphysiologic conditions. In the present study, the specific activities of human gastric lipase (HGL) and pancreatic lipase (HPL) were measured on dietary triglycerides (TGs) during test meal lipolysis. Methods: Healthy … As chitin is a component of the cell walls of fungi and exoskeletal elements of some animals (including mollusks and arthropods ), chitinases are generally found in organisms that either need to reshape their own chitin [2] or dissolve and digest the chitin of fungi or animals.

Endochitinases (EC 3.2.1.14) randomly split chitin at internal sites of the chitin microfibril, forming soluble, low molecular mass See more Chitinases production in the human body (known as "human chitinases") may be in response to allergies, and asthma has been linked to enhanced … See more Regulation varies from species to species, and within an organism, chitinases with different physiological functions would be under different regulation mechanisms. For example, … See more Chitinivorous organisms include many bacteria (Aeromonads, Bacillus, Vibrio, among others), which may be pathogenic or detritivorous. They attack living arthropods, zooplankton or fungi or they may degrade the remains of these organisms. See more Like cellulose, chitin is an abundant biopolymer that is relatively resistant to degradation. Many mammals can digest chitin and the specific chitinase levels in vertebrate species are adapted to their feeding behaviours. Certain fish are able to digest chitin. … See more Chitinases occur naturally in many common foods. Phaseoleus vulgaris, bananas, chestnuts, kiwifruit, avocados, papaya, and tomatoes, for example, all contain significant levels of chitinase, as defense against fungal and invertebrate attack.
