Table 1. Unsaturation index of phospholipids identified in C. albicans biofilms and planktonic cells at early and mature phases.

Unsaturation index for each class was calculated as the mean number of double bonds per fatty acid chain for the species within that class.

^*P-value for each lipid class represents the comparison of levels in biofilms or planktonic cells grown to early (6 h) vs mature (48 h) phases.
