Micromolar

Micromolar is a unit of concentration used in chemistry, biology, and medicine to express amounts of substances in solutions. It is equivalent to one micromole per liter, or 1x10^-6 moles per liter.

Definition

The micromolar (µM) is a unit of concentration used in chemistry and related fields. It represents the concentration of a substance in a solution, specifically one micromole of a substance per liter of solution. This unit is commonly used in biological and chemical experiments where the concentration of a substance in a solution is of interest.

Usage

In biochemistry, the micromolar unit is often used to express the concentration of enzymes in a solution, or the concentration of substrates or products in a biochemical reaction. It is also used in pharmacology to express the concentration of drugs in the body or in a test solution.

In chemistry, the micromolar unit is used to express the concentration of ions in a solution, or the concentration of a chemical compound in a reaction mixture. It is also used in environmental science to express the concentration of pollutants in water or air.

Conversion

The micromolar unit can be converted to other units of concentration, such as millimolar (mM), nanomolar (nM), or picomolar (pM), using the following conversion factors:

• 1 µM = 0.001 mM
• 1 µM = 1000 nM
• 1 µM = 1,000,000 pM
