Accumulation and degradation of three major yolk proteins in Drosophila melanogaster. 1977

M Bownes, and B D Hames

In contrast to previous findings, three major yolk proteins have been identified in the oocytes and eggs of Drosophila melanogaster. They are also present as major proteins in the haemolymph of mature females and in trace amounts in the haemolymph of young females; the male haemolymph lacked all three proteins. Female fat body contained the three proteins and, surprisingly, trace amounts were also present in the male fat body. The accumulation and degradation of the three yolk proteins by oocytes and embryos was asynchronous suggesting that independent controls may exist.

D000273	Adipose Tissue	Specialized connective tissue composed of fat cells (ADIPOCYTES). It is the site of stored FATS, usually in the form of TRIGLYCERIDES. In mammals, there are two types of adipose tissue, the WHITE FAT and the BROWN FAT. Their relative distributions vary in different species with most adipose tissue being white.
