acetic or hydrochloric acid extracts of hypothalamus , pancreas , stomach , and jejunum contained seven molecular forms of mr = 10,400 ( corresponding to prosomatostatin ( pro-s ] , mr = 6,800 ( 7-kda peptide , consisting of an nh2-terminally truncated form of pro-s ) , mr = 7,600 ( 8-kda peptide , corresponding to pro-s- ( 1-76 ) , i.e . pro-s minus the cooh-terminal -arg-lys-s-14 ) , mr = 5,600 ( 5-kda peptide , corresponding to pro-s- ( 33-76 ) ) and three peptides co-chromatographing with synthetic s-14 , s-28 , and s-28- ( 1-12 ) .
