Bromelain belongs to a group of protein digesting enzymes obtained commercially from the fruit or stem of pineapple. Fruit bromelain and stem bromelainare prepared differently and they contain different enzymatic composition. "Bromelain" refers usually to the "stem bromelain." Bromelain is a mixture of different thiol endopeptidases and other components like phosphatase, glucosidase, peroxidase...

BACKGROUND K88 positive enterotoxigenic Escherichia coli (K88+ ETEC) is an important cause of diarrhoea in young piglets. K88+ ETEC pathogenesis relies on attachment to specific glycoprotein receptors located on the intestinal mucosa. Proteolytic treatment of these receptors in vitro and in vivo prevents attachment of K88+ ETEC to piglet small intestines and may be of clinical use to prevent K8...

Bromelain is a mixture of proteinases derived from pineapple stem that is marketed by health food stores as a "digestive aid". A number of studies suggest that bromelain may also have anti-inflammatory activity in vivo, including an anecdotal report describing potential efficacy in inflammatory bowel disease. We and others have previously shown that proteolytically active bromelain removes cert...

Bromelain is a complex mixture of proteinases typically derived from pineapple stem. Similar proteinases are also present in pineapple fruit. Beneficial therapeutic effects of bromelain have been suggested or proven in several human inflammatory diseases and animal models of inflammation, including arthritis and inflammatory bowel disease. However, it is not clear how each of the proteinases wi...

Pineapple (Ananas comosus), Bromeliaceae family, is a fruit grows in tropical countries including Malaysia. This fruit has several pharmacological benefits due to the presence of high concentration of bromelain (cysteine proteases). Condition of elevated temperature will induce deformation of enzyme and result in loss of activity. Sulfhydryl groups in cysteine proteases are readily to be oxidiz...

BACKGROUND Breast cancer is a leading cause of death in women. The available chemotherapy drugs have been associated with many side effects. Bromelain has novel medicinal qualities including anti-inflammatory, anti-thrombotic, fibrinolytic and anti-cancer functions. Commercially available bromelain is obtained through tedious methods; therefore, recombinant bromelain may provide a cheaper and s...

Bromelain is a general name for a family of sulfhydryl that can be found in the proteolytic enzyme group from pineapples (Ananas Comosus). In this study focuses on the prediction of three dimensional structure (3D) of bromelain using homology modelling by MODELLER. The amino acid sequence of bromelain was obtained from the NCBI database and the analysis was done using various bioinformatics too...

The thiol protease, bromelain, an extract from pineapple stem, was suggested to have antithrombotic and anticoagulant activities in vivo. We studied the effects of bromelain on cell size distribution of isolated human platelets in vitro by Coulter Counter measurements. Preincubation of platelets with bromelain (10 micrograms/mL) completely prevented the thrombin (0.2 U/mL) induced platelet aggr...

The purpose of this study is to determine the effect of bromelain produced from pineapple crowns on the quality of beef round cuts. The beef was treated with bromelain at the following condition; the pH of beef was 5.6, the immersion temperature was 60oC, the concentration of bromelain solution was 0.17% and the immersion time was 10 minutes. Bromelain decreased the hardness, water holding capa...
