Carrier (chemistry)
A carrier is a chemical term taken from the English language and translated means "carrier". A carrier accelerates or enables the transport of substances. This mass transfer involves overcoming separating layers (e.g. membranes , phase boundaries , etc.) under the beneficial influence of the carrier.
Examples
- Ion transport: The mass transport of ions through membranes can be made possible by carriers from the group of macrolides .
- Biochemistry: In biochemistry, the passage of adenosine triphosphate and adenosine diphosphate through the mitochondrial membrane is promoted by certain active substances (= carriers).
Use in practice
- Cosmetics: ointment bases are viewed as carriers for active ingredients.
- Textile chemistry: Carriers are known as “tugs” and are used for the accelerated dyeing of textiles, especially synthetic fibers .
