Correction
Following publication of the original article [1] the author advised that unfortunately in the ‘Discussion’ section the letters ‘L’ and ‘D’ in some ‘enantiomer’ expressions were not written in the format of ‘small capitals’. Rather, they were written as lower-case letters.
This formatting is an important nomenclature in chemistry, the author confirmed, advising:
“Enantiomers (mirror-image isomer) of amino acids (L or D) is always expressed by ‘small capitals’ ”
As such, the original article [1] has been corrected to reflect this.
