A hormone that lowers blood glucose levels, possibly an older or alternate term for insulin or a glucose-regulating factor.
From 'gluco-' (glucose) plus '-kinin' (from Greek 'kinesis,' movement); suggesting a substance that causes glucose movement/regulation.
Glucokinin might be an obsolete term for insulin or a related hormone—it shows how medical terminology evolved as scientists better understood how the pancreas actually controls blood sugar!
