일반 설명
Sodium metabisulfite (MBS, Sodium disulfite) is an inorganic salt. It is the sodium salt of disulphurous (pyrosulfurous) acid. It is widely used in textile dyeing, photography and paper industry. It is also commonly added to various food products and wines as a preservative.
애플리케이션
Sodium metabisulfite may be used as an initiator during the cross-linking polymerization of polybutadiene in the cores of the vesicle membranes. It may be added as an antioxidant during the preparation of stock solutions of 6-hydroxydopamine in various studies.

Convergent evidence suggests that amphetamine (AMPH) exerts its rewarding and locomotor stimulating effects via release of dopamine in the nucleus accumbens. However, there is no consensus as to the relative contributions of core and medial shell subregions to these effects.
