Studying living organisms divided into many specialized fields covering their morphology, physiology, anatomy, behaviour, origin, and distribution.. The common earthworm (. Lumbricus. . terrestris. ) is a terrestrial annelid of the class . Oligochaeta. (Baker & Garland, 1982). Earthworms have no specialized respiratory structures and gas exchange occurs by simple diffusion through a liquid film on the surface of the body, which must be kept moist (Curtis & Barnes, 1989). The earthworm has a closed circulatory system, of which the dorsal blood vessel is the principal pumping organ (Hickman et al., 2008). The blood is transported in this vessel by peristaltic waves of contraction and carries food, wastes and respiratory gases (Hickman et al., 2008). A closed circulatory system has an advantage over open systems as it can support a faster metabolic rate (. modified. human proteome . Human proteins exhibit highly complex patterns of posttranslational modifications (PTMs) that govern their structure and function. These modifications are omnipresent in human health and disease. However, technical barriers have limited the study of PTMs which keeps the knowledge of our proteome in a persistent state of “physiological dark matter”. .
