Catalog Number: 3619
Alternate Names: Homotaurine
Chemical Name: 3-Amino-1-propanesulfonic acid
Biological Activity
Sulfated glycosaminoglycan (sGAG) mimetic that targets soluble amyloid β (Aβ) and maintains Aβ in a non-fibrillar form. Decreases Aβ42-induced neuronal death and inhibits amyloid deposition in vitro. Decreases brain amyloid plaque load by 30%, increases tau polymerization and is brain penetrant. Also a GABA analog that protects against the convulsant and cytotoxic activity of kainic acid in vivo.

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)
An example of a molarity calculation using the molarity calculator:
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
