Intestinal absorption of undegraded proteins in men: presence of bromelain in plasma after oral intake - PubMed

The human adult intestinal epithelium has traditionally been described as nonpermeable to proteins. However, indirect evidence suggests that reduced absorption of undegraded proteins might take place under physiological conditions. Using bromelain (an enzyme obtained from pineapple stems) as a model …分類：pmid:9252520, doi:10.1152/ajpgi.1997.273.1.G139, J V Castell, G Friedrich, G E Poppe, Administration, Oral, Adult, Bromelains / administration & dosage, Bromelains / blood, Bromelains / pharmacokinetics*, Dietary Proteins*, Double-Blind Method, Half-Life, Humans, Intestinal Absorption*, Intestinal Mucosa / physiology*, Male, Metabolic Clearance Rate, Random Allocation, alpha 1-Antitrypsin / metabolism, alpha-Macroglobulins / metabolism, PubMed Abstract, NIH, NLM, NCBI, National Institutes of Health, National Center for Biotechnology Information, National Library of Medicine, MEDLINE...
