Galanin — a novel biologically active peptide from porcine intestine

Abstract
The isolation of a novel biologically active peptide, designated galanin, is described. The peptide was discovered by the detection of its C‐terminal amide structure in porcine intestinal extract using a chemical method. It was found that galanin consists of 29 amino acids and the complete amino acid sequence is: contract smooth muscle preparations from the rat and to cause a mild and sustained hyperglycemia in dog.
