What does Zinc, Serum Measure?
Zinc is a mineral which is a micronutrient (required by the body in small amounts). It has a number of essential roles in the body. Zinc is a structural component of a number of proteins. It is essential in the synthesis of proteins and DNA, for cell division, and is necessary for proper enzymatic activity. It is also essential in the proper functioning of the immune system and in wound healing. Zinc is essential for proper physical and mental growth and development of children. It is also essential for the senses of taste and smell.
Zinc is absorbed primarily from dietary sources. It is transported in the serum bound to proteins, namely, albumin and alpha-macroglobulin. Excess zinc is disposed out of the body primarily through the feces, and a small amount through urine and sweat. The absorbed amount of zinc is utilized by almost all the cells of the body but is not stored anywhere in particular.
