incorporation of selected amino acids by resting cells was studied with regard to effects of concentration , rate and extent of incorporation , cellular distribution , effect of ammonium ion on uptake , and competitive effects . l-aspartic acid , l-alanine , l-serine , and glycine presented at trace levels were incorporated at rates ranging from 0.11 to 8.2 mumumoles per mg ( dry weight ) per minute , and maximal incorporation was 11 to 333 mumumoles per mg ( dry weight ) .
