Summary The plasma aminogram was investigated in newborns from a low socio‐economical group of West Pakistan with an increased frequency of the “small for dates” syndrome. The plasma levels of proline and glycine increased during the first hours of life to levels significantly higher than those of a Swedish normal material. The alanine levels showed a “resistance to decline” during this period. The branch‐chained amino acid levels of plasma showed a fast decline after a temporary “resistance to decline”. The plasma free amino acid levels changed during the first hours of life to a pattern, which is the same as that seen in protein deficiency.
