Correction to: Nature https://doi.org/10.1038/nature25137, published online 10 January 2018.

In the top right panel of Fig. 1a of this Letter, we inadvertently showed the chemical structure of elaidic acid (trans-9-octadecenoic acid), rather than that of oleic acid (cis-9-octadecenoic acid) used in the paper. Figure 1 of this Amendment shows the original and corrected structures. This error has not been corrected online.

Fig. 1: This figure shows the original and corrected top structure of the right panel of Fig. 1a of the original Letter.
