The Further Purification of Motilin, a Gastric Motor Activity Stimulating Polypeptide from the Mucosa of the Small Intestine of Hogs
Abstract
A polypeptide has been isolated from the duodenal mucosa of hogs and has been named motilin. Motilin stimulates motor activity in both antral and fundic gland area pouches of the stomach of dogs. It will stimulate pepsin output, with no change in H+ secretion, from fundic gland area pouches. Motilin differs from the other characterized gastrointestinal polypeptides both chemically and in its physiological actions. In particular, the presence of phenylalanine as N-terminal residue, the absence of histidine, and presence of large amounts of glutamic acid and glutamine distinguish it from cholecystokinin–pancreozymin and secretin.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
