Abstract
Abstract Valine, lysine, phenylalanine, arginine, histidine, threonine, leucine, isoleucine, and tyrosine were not readily synthesized from glucose-U-C 14 by the prairie grain wireworm and, except for tyrosine, are classed as nutritionally essential. Tyrosine was readily formed from phenylalanine. Although methionine and glutamic acid were synthesized to a limited extent, they are considered to be nutritionally essential also. In contrast, proline, alanine, aspartic acid, serine, and glycine were readily synthesized from glucose-U-C 14 and are classed as nutritionally non-essential. A peptide containing leucine, glycine, and glutamic acid was demonstrated and may be of nutritional significance. The relative quantities of the common amino acids found in this insect are presented.
