Compound	Description
hydronium ion
uridine diphosphate	A uracil nucleotide containing a pyrophosphate group esterified to C5 of the sugar moiety.
Magnesium	A metallic element that has the atomic symbol Mg, atomic number 12, and atomic weight 24.31. It is important for the activity of many enzymes, especially those involved in OXIDATIVE PHOSPHORYLATION.
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)
Oxygen	An element with atomic symbol O, atomic number 8, and atomic weight [15.99903; 15.99977]. It is the most abundant element on earth and essential for respiration.
soyasaponin I	from roots of Gypsophila sp.; dominant saponin found in most legumes
UDP-rhamnose
soyasapogenol b	RN given for (3beta,4beta,22beta)-isomer; structure in first source
2,3-oxidosqualene	an oxidized derivative of SQUALENE that can fold in several ways: chair-boat-chair-boat to LANOSTEROL; chair-chair-chair-boat to dammarane; or all chair to hopane and on to cycloartenol; RN given refers to (all-Z)-isomer
sophoradiol	RN refers to (3beta,22beta)-isomer; structure in first source
