Minerals, in the body

Abuse of diuretics can lead to problems similar to those resulting from laxative abuse. These include imbalances of certain minerals in the body. Of particular concern is potassium, which is needed at certain concentrations for the heart to pump correctly. Not having enough potassium in the body can lead to an irregular heartbeat, which can result in death. Kidney damage and dehydration are other health risks associated with diuretic abuse. 

The health sciences are a group of disciplines that draw upon chemistry, physics, and biology. How does chemistry relate to the health sciences Knowing about molecular structure and function allows biochemists to synthesize medicinal compounds on a large scale, and even to design new molecules to fight diseases and their symptoms. Understanding the chemical role of nutrients, vitamins, and minerals in the body helps...

Sodium, potassium and chloride are the primary dietary ions that influence the electrolytic balance and acid-base status, and the proper dietary balance of sodium, potassium and chloride is necessary for growth, bone development, eggshell quality and AA utilization. Potassium is the third most abundant mineral in the body after calcium and phosphorus, and is the most abundant mineral in muscle tissue. It is involved in electrolyte balance and neuromuscular function. The content of potassium in poultry diets is usually adequate. Chloride is present in gastric juice and chlorine is part of the HC1 molecule which assists in the breakdown of feed in the proventriculus. Sodium is essential for nerve membrane stimulation and ionic transport across cell membranes. Signs of sodium, potassium or chloride deficiency include reduced appetite, poor growth, dehydration and increased mortality. 

Calcium is the most abundant mineral in the body, about 1 kg, 99% of which is found in the skeleton in the form of calcium phosphate salts. There is a significant exchange of calcium between the bone and extracellular fluid (ECF) serum levels of calcium are tightly regulated (it can vary with the level of serum albumin, to which calcium is bound). 

Cadmium is chemically similar to the metal zinc, and is absorbed from the gut in a similar way using the same system. It can interfere with zinc in the body and consequently may affect the male reproductive system where zinc is important. Cadmium interferes with the metabolism of calcium too, a critical mineral in the body with which it also has similarities. This interference leads to loss of calcium from the bones which then become brittle (osteomalacia). In the case of itai-itai disease, which was the result of cadmium poisoning in Japan, the exposure to cadmium was accompanied by a deficiency of vitamin D which made the problems with the bones worse. 

As I explain in chapter 9, it may be more important to increase and thus balance levels of minerals in the body (electrolytes), including magnesium, calcium, and potassium, than it is to reduce the mineral... 

Bone is composed of live cells interspersed in an organic matrix. Inorganic elements or minerals (65%) are deposited into this organic matrix (35%), which makes bone one of the few tissues that normally mineralize. The principal inorganic element in bone is calcium hydroxyapatite (Caio (P04)0H2), which accounts for 99% of the calcium and 80% of the stores of these respective minerals in the body. Calcium hydroxyapatite provides bone with strength and hardness. The organic matrix provides a degree of elasticity to bone. 

The functions of minerals in the body involve building tissue and regulating numerous body processes. Their role in the human body is summarized in Table 4.3. 

Calcium A basic element found in nearly all organized tissues. It is a member of the alkahne earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes, [nih]... 

If body fluids become too diluted, then soditun concentrations in the blood drop dramatically. Sodium is an essential mineral in the body, and it plays a critical role in the transmission of nerve impulses in the brain and the muscles. Our bodies regulate the concentration of sodium in our blood by moving water in and out of the blood. If you have a high sodium concentration, then water moves from your cells into yoiu blood, increasing your blood pressure. As water moves from your brain cells into your blood, your brain actually shrinks, and you may experience confusion and seizures. If your sodium concentration is low, then the reverse happens water moves...

The general functions of trace minerals in the body are to serve as components of vitamins (Co), enzymes (Zn, Se), hormones (I), or specialized proteins (Fe, Cu). 

Phosphorous is an important element in essentially all existing forms of life. In human beings, phosphorous is found predominantly in the form of phosphate. Phosphate is the sixth most abundant mineral in the body and is the most abundant intracellular anion in the body. It provides the energy-rich bonds of adenosine triphosphate (ATP) used for multiple processes in the body, including... 

A Calcium is the most well-known and abundant mineral in the body. It is an essential part of our bones and teeth, but it also plays a role in muscle, nerve, and blood vessel function. Blood levels of calcium, which represent only 1% of total body calcium (the rest is in our bones), are tightly controlled within a narrow range. Unfortunately, if you don t consume adequate amounts of calcium, your body gets what it needs from your bones, which can lead to a decrease in bone density known as osteoporosis. Bone density peaks at about the age of 30, so it is very important to consume adequate amounts of dietary calcium before age 30 to build up bone to optimal levels, and after age 30 it is important to preserve bone as much as possible. Bone undergoes constant turnover, and so it requires a constant supply of calcium. In addition to its role in reducing the risk of osteoporosis, research suggests that adequate dietary calcium may also decrease the risk of colorectal cancer. The recommended daily allowance (U.S. RDA) of calcium for adults (the amount considered adequate to meet the needs of 97-98% of healthy individuals) is shown in the following table ... 

As the main structural material for bones and teeth, caldnm is the most abundant mineral in the body. Calcium also plays an important role in nerve signal transmission and in blood clotting. If blood calcium levels get too low, calcium stored in bones will release into the blood causing loss of bone mass. Persistently low blood calcium levels result in osteoporosis, a condition in which bones become weakened by calcium loss. The adult DRI for calcium is 1000 mg/day. Adolescents and older adults need a bit more. One cup of milk contains approximately one-third of the adult DRI. Other calcium-rich foods include cheese, sardines, oysters, and broccoli. 

PhospliDrus is the second most abundant mineral in the body and is largely bound with calcium in bones and teeth. Phosphorus also assists in energy metabolism and is part of DNA. The adult DRI for phosphorus is 700 mg/day and is easily met with almost any diet, making deficiencies unknown. 

In addition to metabolic fuels and protein, the body has a requirement for a variety of mineral salts, in small amounts. Obviously, if a metal or ion has a function in the body, it must be provided by the diet, as the different elements cannot be interconverted. Again, the need is obvious for a growing child as the body grows in size, so the total amounts of minerals in the body will increase. In adults, there is a turnover of minerals in the body, and losses must be replaced from the diet. 

The breakthroughs in our understanding of the functions of minerals in the body did not come for many centuries because laboratories for research were not developed until the Renaissance although the medieval alchemists appear to have invented some of the techniques and tools of chemistry in their futile efforts to change base metals into gold. 

Calcium is the most abundant mineral in the body. It mekes up about 2.0% of the body waighi, or about 40% of the total mineral present SS% of It is in the bones and teeth. 

Some of the sources of iron which may lead to overaccumulation of the mineral in the body are (1) acid foods which... 

It is not wise for lay people to attempt to interpret laboratory tests for mineral deficiencies without the aid of a doctor, because many factors other than the diet may raise or lower the levels of minerals in the body liquids and the tissues. Therefore, some of the better-known types of diagnostic tests are covered briefly, so that the reader may be knowledgable when discussing them with his or her physician. These follow ...
