Mikroaineista

Mikroaineista, also known as microelements or trace elements, are chemical elements that are essential for the growth and development of living organisms, but are required in very small quantities. Despite their low concentrations, they play critical roles in various biological processes. These essential elements are not synthesized by the body and must be obtained through diet or other external sources.

The specific set of elements considered micronutrients can vary slightly depending on the organism, but commonly include metals like iron, zinc, copper, manganese, and molybdenum, as well as non-metals like iodine and selenium. For humans, iron is vital for oxygen transport in the blood, zinc is crucial for immune function and wound healing, and iodine is necessary for thyroid hormone production. Copper is involved in enzyme activity and energy production, while manganese plays a role in metabolism and bone formation. Selenium acts as an antioxidant and is important for thyroid function.

Deficiencies in micronutrients can lead to a range of health problems. For instance, iron deficiency causes anemia, iodine deficiency can result in goiter and developmental issues, and zinc deficiency can impair immune responses and growth. Conversely, excessive intake of certain micronutrients can also be harmful, leading to toxicity. Therefore, maintaining a balanced intake within recommended dietary allowances is crucial for optimal health. Their small but vital contribution underscores their significance in biochemistry and human nutrition.
