Sometimes, the specific oligomers were not known at the time the asymmetric unit was published. Also, some authors failed to specify the biological unit even when it was known. Rarely, the specified biological units might be incorrect. For all these reasons, it is advisable to consult sources other than REMARK 350. | Sometimes, the specific oligomers were not known at the time the asymmetric unit was published.
