Iodine value, saponification number and refractive index of the fat from fresh eggs are rather constant, but only under a given experi- mental condition. 3. The main source of fat in an egg is the egg yolk, which furnishes the fat for nutrition and energy-supply of the developing Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
