by observing the labelling of the different mycolate pools in the cell , i.e . the organic-solvent-extractable fraction ( essentially containing esters of trehalose and of glycerol ) and the cell residue ( assumed to be the cell-wall polymers ) , it was clear that oxomycolates and unsaturated mycolates appeared first in the extractable lipids , then in the wall-linked mycolates while wax-ester mycolates appeared first as wall-linked derivatives .
