The primary constituents of blue crab yolk are lipovitellin and lipid droplets.

N-Terminal domain of apolipoprotein B has structural homology to lipovitellin and microsomal triglyceride transfer protein: a "lipid pocket" model for self-assembly of apoB-containing lipoprotein particles.
(1986) suggest that carotenoids are transported from the muscles to the gonads by a carotenoid-carrying lipoprotein called vitellogenin (a female-specific serum lipoprotein produced by the liver) during spawning migration, and accumulate in egg yolk (where they bind to lipovitellin).
Until they emerge from egg sacs, embryos are nutritionally dependent on lipids and lipovitellin stored within the eggs.
Incorporation of lipovitellins from labeled femalespecific proteins into vitellogenic oocytes is characteristic in decapod crustaceans (Adiyodi & Subramoniam, 1983).
Sequence analysis also shows that part of mammalian apoB is homologous to the lipovitellins, one of the major lipid transporting proteins of birds for egg yolk lipid deposition (Baker, 1998; Jolivet et al., 2006).
Two forms of vitellogenin, yielding two distinct lipovitellins, play different roles during oocyte maturation and early development of barfin flounder, Verasper moseri, a marine teleost that spawns pelagic eggs.
