<I>The distribution of</I> <SUP>14</SUP>C-<I>amino acid</I> (<SUP>14</SUP>C-<I>glycine</I>, <SUP>14</SUP>C-<I>isoleucine</I>, <SUP>14</SUP>C-<I>valine</I>, <SUP>14</SUP>C-<I>aspartic acid and</I> <SUP>14</SUP>C-<I>glutamic acid) has been studied by means of autoradiographic method with whole animal slice section of</I> 10 <I>days old baby mouse</I>.<BR><I>The distribution pattern of these amino acids seemed to be divided into two types. One was in the case</I>, <SUP>14</SUP>C-<I>isoleucine</I>, <SUP>14</SUP>C-<I>valine and</I> <SUP>14</SUP>C-<I>glycine being injected, their radioactivity in all tissues reached the high level at</I> 7 hrs <I>after administration and continued over</I> 96 hrs. <I>The other was in the case</I>, <SUP>14</SUP>C-<I>aspartic acid and</I> <SUP>14</SUP>C-<I>glutamic acid being injected, the intense activity was noted at</I> 3 <I>and</I> 24 hrs., <I>respectively, but it gradually disappeared and scarcely detected in tissues at</I> 96 hrs. <I>Besides, it was of interest that in the early period after injection</I> <SUP>14</SUP>C-<I>aspartic acid and</I> <SUP>14</SUP>C-<I>glutamic acid, specific and dense localization of</I> <SUP>14</SUP>C <I>occurred in the skeleton</I>.
