The avoidance of D-tryptophan by the nematode Caenorhabditis elegans
The Journal of Experimental Zoology
|September 1, 1975
Abstract:
In chemotactic studies employing countercurrent separation the nematode aenorhabditis elegans was found to avoid D-tryptophan with a threshold in the range 10(-4) to 10(-3) M. There was no response to L-tryptophan up to 10(-2) M although it appeared to partially inhibit the response to D-tryptophan.
