GLAST-1

   A high affinity glutamate/aspartate transporter found in astrocytes, heart, skeletal muscle and placenta. Its action can be coupled to the co-transport of potassium, sodium or hydrogen ions.

Affinity
A measure of the binding constant of a single antigen combining site with a monovalent antigenic determinant.

Heart
The hollow, muscular organ responsible for pumping blood through the circulatory system.

Muscle
Tissue made up of bundles of long, slender cells that contract when stimulated.

Placenta

Sodium
A mineral found in most of the foods we eat. The largest source of dietary sodium comes from sodium chloride or table salt. Intake of sodium tends to increase the retention of water.

Hydrogen
Hydrogen. The first chemical element in the periodic table. It has the atomic symbol H, atomic number 1, and atomic weight 1. It exists, under normal conditions, as a colorless, odorless, tasteless, diatomic gas. Hydrogen ions are PROTONS. Besides the common H1 isotope, hydrogen exists as the stable isotope DEUTERIUM and the unstable, radioactive isotope TRITIUM.
