_chem_comp_chir.volume_three
Name:'_chem_comp_chir.volume_three'
Definition:
The chiral volume, V~c~, for chiral centres that involve a chiral atom bonded to three non-hydrogen atoms and one hydrogen atom. V~c~ = V1 * (V2 X V3) V1 = the vector distance from the atom specified by _chem_comp_chir.atom_id to the first atom in the CHEM_COMP_CHIR_ATOM list V2 = the vector distance from the atom specified by _chem_comp_chir.atom_id to the second atom in the CHEM_COMP_CHIR_ATOM list V3 = the vector distance from the atom specified by _chem_comp_chir.atom_id to the third atom in the CHEM_COMP_CHIR_ATOM list * = the vector dot product X = the vector cross product
