Introduction
Transition metals are metals that contain two shells in their valence electrons rather than one shell.
However, the inners shells of the transition metals are incomplete, and this allows valence
electrons only in the inner shell and not in the outer shell (Loup et al., 2019). Besides, transition
metals conduct both heat and electricity, and they are found at the center of the periodic table.
However, there are various types of transition metals, including cobalt, nickel, iron, copper, and
manganese. This paper focuses on explaining on how transition metals are important and their
purpose in the body and their toxicity, as discussed below.
Role of Transition metals in Human Body
Transportation of Oxygen
Iron, which is a member of transition metals, is used in producing blood in the body. Biologically,
about 70% of the iron in the body is found in the hemoglobin and myoglobin of the red blood cells.
However, the hemoglobin Is used to transport oxygenated blood from the lungs to other body parts.
Maintaining the Healthy of Bones and Immune System
Transition metals, especially copper, help strengthen and maintain healthy bones, ensure the
proper functioning of the immune system, and maintain the health of blood vessels in the body,
hence preventing heart and blood diseases.
Synthesis of Vitamin B12
B12 is an essential nutrient in the body that ensures healthy blood cells and nerves and is used in
the production of DNA in the body, and thus its creation in the body is always essential. The
synthesis of the B12 process in the body is sometimes hard. However, cobalt, which is an example
