The molecule is a polyprenyl glycosyl phosphate consisting of 4-deoxy-4-formamido-alpha-L-arabinopyranose attached at the 1-position to di-trans,poly-cis-undecaprenyl phosphate. It derives from a 4-amino-4-deoxy-alpha-L-arabinopyranose. It is a conjugate acid of a 4-deoxy-4-formamido-alpha-L-arabinopyranosyl ditrans,polycis-undecaprenyl phosphate(1-).
