Ara h 6 is one of the major allergenic proteins from peanut (Arachis hypogaea) which contains approximately 13 potential allergenic proteins. Ara h 6 is a member of the 2S albumins (conglutinins) belonging to the prolamin superfamily which also includes Ara h 2. 2S albumins contain major food allergens from seeds of many mono‐ and dicotyledon plants and share a common compact structure that renders the proteins highly resistant to proteolysis.

Ara h 6 contains multiple disulphide–bridged cysteine residues, resulting in a tightly coiled, heat-stable, protease resistant core structure that may be important for allergenicity. In mouse models Ara h 2 and Ara h 6 are the main cause of effector responses such as mast cell degranulation and anaphylaxis.

This peptide represents a tryptic peptide of Ara h 6. The phenylalanine residue at position 11 of this peptide is isotopically labelled with carbon-13 (9) and nitrogen-15 (1), giving this peptide a mass increase of 10 compared to the unlabelled peptide.
