title: [A statistical study on distribution patterns of plasma free amino acids].
abstract: We investigated the distribution patterns of 23 plasma free amino acids in 875 healthy adults (375 males and 500 females, aged from 30 to 50 years), which were obtained after an overnight fast, using three statistical parameters of MLL (Maximum Logarithmic Likelihood), square root of b1, b2, and selected their patterns from the three of ordinary normal, log-normal and square root-normal distributions. The distribution patterns of the majority of plasma free amino acids were found to be either log-normal or square root-normal, and occasionally ordinary normal. We also evaluated the reliability of our selection system by a simulation model of 100 sets of values for plasma free amino acids that were randomly determined by the parameters of original data. Good reliability was observed for some amino acids. Our selection system may be useful for comparing the present results with the future results that will be obtained by other methods.
