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.
从牛、羊和山羊皱胃中提取的不同类型和亚型的胃蛋白酶原，根据其磷酸盐含量和相对分子质量（Mr）而有所不同。牛胃蛋白酶原的有机磷酸盐含量为每摩尔胃蛋白酶原含1.65至2.22摩尔磷酸盐。羊胃蛋白酶原的含量范围为1.50至2.36，山羊胃蛋白酶原的含量范围为1.42至2.00。每个物种的主要胃蛋白酶原类型在大小上有所不同。牛胃蛋白酶原的Mr为39,000，羊胃蛋白酶原的Mr为43,000，山羊胃蛋白酶原的Mr为,42,000。
