Abstract
An amino acid pattern distribution map of 68 Japanese foods was prepared. For this purpose radian distances between each amino acid pattern were calculated. Radian distance R (A, B) between pattern A (α1, α2…, αn) and pattem B (b1, b2…, bn) was defined as follows,
in which θ is an angle between vector OA and vector OB. For the preparation of the map, the nearest two radian distances with an amino acid pattern of each food were used. Natures of the amino acid pattern distribution clarified in the map were discussed.
