CCK (26-31) (sulfated)

CCK (26-31) is an N-terminal fragment of CCK (Cay-23371, Cay-24404), a peptide hormone found in the intestine and brain that stimulates digestion, mediates satiety, and is involved in anxiety. The sulfated form of CCK (26-31) inhibits binding of [125I]CCK-33 to guinea pig cortical membranes by 21% when used at a concentration of 0.1 mM.Formal Name: N-acetyl-L-alpha-aspartyl-O-sulfo-L-tyrosyl-L-methionylglycyl-L-tryptophyl-L-methioninamide.
