개불, urechis unicinctus의 생식주기에 따른 아미노산 변화

Protein and amino acid compositions on reproductive cycle of Urechis unicinctus

In order to evaluate the marine mollusc as foodstuff not only from the biochemical aspect but also from the view point of food science, we have analyzed the protein and amino compositions of the Urechis unicinctus on reproductive cycle. We sampled Urechis unicinctus from January te June, 1999 in Yosu. Urechis unicinctus’s muscle contained about 12.95~16.63% of protein, 0.01~0.47% of fat, 78.93~83.41% of moisture and 2.59~3.48% of ash. The total amino acid compositions change in the muscle of Urechis unicinctus was found to be very similar reproductive cycle of Urechis unicinctus. The major amino acid of Urechis unicinctus’s muscle protein was glutamic acid, glycine, alanine, leucine, and asparactic acid in order.
