There are light and dark areas, which correspond to different stages of fat conservation. The clear area termed “white”, corresponds to an intermediate state of formation of a structure called “adipocere”, which corresponds to the result of saturation of unsaturated fatty acids. The dark “brown” area is the primeval fat, which contains hairs (H) and the unchanged fatty acids.
