Effect of anionic SNPs on detection of amino acids in human urine sample.a

Amino acid Charge Suppressed
Alanine 0 No
Arginine +1 Yes
Asparagine 0 No
Aspartic acid −1 No
Glutamic acid −1 No
Glutamine 0 No
Glycine 0 No
Lysine +1 Yes
Serine 0 No
Threonine 0 No

a

Metabolites whose NMR spectrum was suppressed by SNPs in the urine sample. Other amino acids were either not present or below the detection limit.
