Background

Ghrelin is a 28 residue pepetide expressed by stomach cells that is responsible for the hunger sensation. Expression is increased during times of fasting, and decreased after food consumption. Ghrelin is initially derived from a preprohormone called preproghrelin, which also generates a second peptide called obestatin. Obestatin is an endogenous ligand for the orphan G protein-coupled receptor GPR39 and is involved in satiety and decreased food intake. Ghrelin antibodies are useful tools for lipid and metabolism research as well as neuroscience studies.

Limitations

Molarity Calculator

Calculate the mass, volume, or concentration required for a solution.

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)

As an example, if the molecular weight of a compound is 197.13 g/mol and the desired concentration is 10 mM for 10 ml of water based stock solution, the required mass would be = 19.713 (value determined by this calculator).
