Abstract:
Different types and subtypes of pepsinogen extracted from bovine, ovine and caprine abomasa were found to differ according to their phosphate content and relative molecular mass (Mr). Bovine pepsinogens had organic phosphate contents ranging from 1.65 to 2.22 mol of phosphate mol-1 of pepsinogen. Ovine pepsinogens were in the range 1.50 to 2.36 and caprine pepsinogens were in the range 1.42 to 2.00. The major types of pepsinogen from each species were different in size. Bovine pepsinogen had an Mr of 39,000, ovine had an Mr of 43,000 and caprine pepsinogen had an Mr of 42,000.
