Results from this study2

No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone2

In this study, Kisspeptin-54 (metastin) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Kisspeptin-54 (metastin).

  1. 01LabNot a test of Kisspeptin-54 (metastin) aloneIn vitro (cell-free)Mechanism

    In water and in trifluoroethanol/water mixed solvent, kisspeptin‑54 is mostly disordered with no structural motifs.

    In plain wordsIn lab tests, kisspeptin‑54 had little fixed shape in water and in a water and alcohol mix.

    Summary · context
    The current studies were undertaken in order to determine structure of KP-54 using nuclear magnetic resonance and circular dichroism.

    In this study, Kisspeptin-54 (metastin) was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking Kisspeptin-54 (metastin).

  2. 02LabNot a test of Kisspeptin-54 (metastin) aloneIn vitro (cell-free)Mechanism

    In sodium dodecyl sulfate micelles, kisspeptin‑54 stays mostly disordered, with a small rise in helical propensity compared with water.

    In plain wordsIn lab tests, kisspeptin‑54 stayed mostly unstructured in soap-like micelles, with a small rise in helical shape.
