1) Pyruvic acid in human milk with different Arakawa's reaction was determined using my own modification.
2) Human milk positive to Arakawa's reaction contained smaller amounts of pyruvate than the Arakawa-negative milk, -and milk with inter-mediate Arakawa's reaction showed intermediate values of milk pyruvate between those positive and negative to Arakawa's reaction.
