This small protein molecule contains a loop which fits, like a key in a lock, into the ion channel proteins found on nerve cell membranes, which are used to
transport sodium and potassium ions in and out of the cell.
Not exact matches
For example, ATP1B1 encodes a sub-unit of the
sodium -
potassium plasma membrane pump, which is essential for water
and ion
transport.
Taurine is actually the second most abundant amino acid in the body (the first being glutamine), found in high concentrations in the skeletal muscles
and the brain, where it aids the
transport of
potassium, calcium,
sodium and magnesium, which nearly qualifies it as a neurotransmitter.
Like
sodium and potassium, or calcium
and magnesium, zinc
and copper have overlaps in
transport and metabolism.
In particular, magnesium - dependent proteins are used to facilitate the
transport of different minerals into
and out of cells, acting as gates for
sodium (Na +),
potassium (K +)
and calcium (Ca +).
After their removal (using a string attached to the base) water
transport was determined by weight difference,
and the concentration of electrolytes (
sodium,
potassium, bicarbonate,
and chloride) was measured spectrophotometrically.
