Abstract

The silkworm larvae at the 5th instar excreted 0.66-0.77% of combined glycine in their feces (I) between 1st and 8th day, whereas a large amount of combined glycine was detected in the feces (II) of matured (matured) silkworm (green feces and rid feces contained 3.28% and 13, 04%, respectively, of combined glycine). Glycine was easily liberated by hydrolysis from I but with difficulty from II. Ratios of glycine-N to total-N in I, green feces, red feces, and mulberry leaves were 6.28%, 11.89%, 15.86%, and 6.80%, respectively. These results suggest that glycine in I may be liberated from indigested proteins of mulberry leaves and that in II from uric acid or some purine derivatives, which liberate glycine under drastic hydrolysis conditions.
