^aAbbreviations: Ac, acetyl; Ara, arabinosyl; Cb, carbamoyl; Fuc, fucosyl; H, hydrogen; Me, methyl; S, sulfate; MeFuc, methylfucose; AcMeFuc, acetylated methylfucose; SMeFuc, sulfated methylfucose. 

^bIn USDA191, a minor fraction of the N-acetylglucosamine marked in brown is replaced by a glucose. 

^cCarbamoyl group is either on R2 or R3. 

^dR. huakuii Nod factors are partially glycolylated at the C-2 position of the reducing terminus.
