Disclosure of Chemical Structures
At the time of abstract submission, the submitting author is required to state whether chemical compounds were used in the scientific work to generate the data in the proffered paper. Chemical compounds are defined as low-molecular-weight (generally <1000 g/mol) organic or inorganic molecules, peptides, or proteins/nucleic acids co-crystallized with low-molecular-weight molecules.
If chemical compounds were used, the corresponding author is further required to indicate whether the complete chemical structures of the compounds used will be disclosed at the time of presentation at the meeting. The chemical structures are not required to be included at the time of abstract submission; rather, an indication of the intent to disclose any such structures at the time of presentation is required.
The Program Committee will then evaluate the information provided by the corresponding author and determine the acceptability of the proffered paper for presentation. Those who do not intend to disclose chemical structures may have their abstracts rejected for participation; however, a limited number of these abstracts may be accepted for presentation if deemed to be of sufficient scientific merit.
Submission FeeEach abstract submitted must be accompanied by a $65 abstract submission fee. The submission fee can be paid by credit card or check. The fee is nonrefundable regardless of the final disposition of the abstract.

11:59 p.m. U.S. ET, Thursday, Dec. 5, 2019. Abstracts submitted after the deadline will not be considered by the Program Committee. No changes may be made to abstracts after the Dec. 5, 2019, deadline.
