Biconcave disc (original) (raw)

A biconcave disc — also referred to as a discocyte — is a geometric shape resembling an oblate spheroid with two concavities on the top and on the bottom. Biconcave discs appear in the study of cell biology, where it is meta-stable, and involves the continuous adjustment of the asymmetric transbilayer lipid distribution, which is correlated with ATP depletion.
