Galanin (1-13)-spantide I is a chimeric peptide composed of the N-terminal fragment of galanin (amino acids 1-13) and spantide, a known substance P receptor antagonist. Galanin (1-13)-spantide I has a high affinity for spinal galanin receptor (Kd=1.16 nM). Galanin (1-13)-spantide I can be used to study the effects of galanin on feeding behavior.

L-Glucose is an enantiomer of D-glucose. L-Glucose is not bioavailable to cells as an energy source because it cannot be phosphorylated by hexokinase.

Ammonium sulfate is one of the compounds commonly used in inorganic experiments as an oxidizing agent and bleaching agent.
