Symptoms as Consequences of Nutritional Disorders

The mineral nutrient elements take part in many processes. Interestingly enough, most elements are involved simultaneously in different reactions of metabolism. Thus, P, K, Mg, Ca, and B are important for the formation of nucleic acids, production of nucleotide phosphates, energy metabolism, and stabilization of membrane structures. Zn is a component of many different enzyme processes, and even Mn and Fe are involved in various reactions. Therefore, no clear assignment of individual elements to distinct areas of metabolism is possible. Indeed, results obtained with different vege-
