The Trace elements Are bioelements present in all living beings, being chemical elements that can be found in almost any living particle. Trace elements are normally found at low concentrations (mg kg −1 or less) in living organisms. Here is rundown on the most important trace elements: Iron is an essential component of many proteins and enzymes. The amount that can be consumed of the trace elements is very small, but through a Healthy and balanced diet It is easy to get to consume the recommended daily amount of these products. Chromium is an essential trace element for people. Another essential element that makes up the bones. Zinc is required for growth, normal development, DNA synthesis, immunity, and sensory functions.

In addition it influences activities to obtain energy from the cells. In Clinical Nutrition of the Essential Trace Elements and Minerals: The Guide for Health Professionals, John Bogden, PhD, Leslie Klevay, MD, and a host of recognized experts address this major gap in the literature with a comprehensive, up-to-date survey of the biological roles and clinical importance of mineral and trace element nutrients. Most likely, insufficient intake of a specific trace element becomes obvious only when the body is stressed in some way that enhances the need for that element; this has been supported by recent findings with selenium. Trace element definition, any element that is required in minute quantities for physiological functioning. Très faible quantité d'une substance : Déceler des traces d'albumine dans les urines.

Potassium elements increase the quality of fruits and vegetables; Potassium, sodium, magnesium and other elements are involved directly in the metabolism of the plant. This chemical element is very necessary for humans since the thyroid gland needs it to manufacture thyroid hormone and thyroxine. Philos Trans R Soc Lond B Biol Sci. Trace elements have been extensively studied in recent decades and have wide roles in biochemical mechanisms both as essential and toxic elements (Guengerich, 2009). carbon, hydrogen, oxygen, and nitrogen), plants, animals, and microorganisms all require a range of elements in inorganic forms in varying amounts, depending on the type of organism.
