Compound	Description
hydronium ion
Orthophosphate
adenosine diphosphate	Adenosine 5'-(trihydrogen diphosphate). An adenine nucleotide containing two phosphate groups esterified to the sugar moiety at the 5'-position.
Water	A clear, odorless, tasteless liquid that is essential for most animal and plant life and is an excellent solvent for many substances. The chemical formula is hydrogen oxide (H2O). (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
glutamate
adenosine triphosphate	An adenine nucleotide containing three phosphate groups esterified to the sugar moiety. In addition to its crucial roles in metabolism adenosine triphosphate is a neurotransmitter.
Cysteine	A thiol-containing non-essential amino acid that is oxidized to form CYSTINE.
Phytochelatins	Poly-glutathione peptides composed of (Glu-Cys)n-Gly where n is two to seven. They are biosynthesized by glutathione gamma-glutamylcysteinyltransferase and are found in many PLANTS; YEASTS; and algae. They sequester HEAVY METALS.
