An extremely intense band of around 140 kDa is present in all of these embryonic stages, and likely represents the cleavage product of the large Vtg2 precursor into the N-terminal lipovitellin I product, as observed in chicken Vtg2 (Yamamura et al., 1995).
Female crustaceans convert a proportion of TG into PC to form lipovitellin, which is the major constituent of egg yolk (Lee et al.
Vitellogenin is synthesized in the liver and transported via the blood stream to the oocytes where it enters via endocytosis and is enzymatically cleaved into phosphovitins and lipovitellin, which are the major proteins contributing nutrients and lipids for the developing embryo [2].
The principal component of blue crab yolk is lipovitellin, a water-soluble lipoprotein composed of similar amounts of lipids and proteins.

The [beta][[alpha].sub.1]-domain consists of the first 1000 amino acids of apoB and is a globular domain with homology to lipovitellin, an egg yolk lipoprotein (6).
Subramoniam (2011), reported that the egg yolk of crustaceans is composed of large quantities of the protein vitellogenin linked to lipids, forming a complex referred to as lipovitellin. Dietary protein was the same in all the diets, so with the increment of egg production in the females with higher lipid inclusions, protein must be mobilized at a higher rate than the lipid.
The vitellogenin cDNA of Cherax quadricarinatus encodes a lipovitellin with calcium binding ability, and its expression is induced following the removal of the androgenic gland in a sexually plastic system.
Once inside the oocyte, VTG is cleaved into the smaller yolk proteins (phosvitin, lipovitellin, and beta-component), which accumulate in yolk globules or granules (42).
