The mineralocorticoids consist of aldosterone and des-oxycorticosterone and play an important role in conserving sodium and increasing die excretion of potassium. Because of diese activities, die mineralocorticoids are important in controlling salt and water balance Aldosterone is die more potent of these two hormones. Deficiencies of the mineralocorticoids result in a loss of sodium and water and a retention of potassium.

Potassium contributes to the formation of sugars, carbohydrates, proteins and to cell division adjusts water balance enhances the flavor, color, and oil content of fruits and is very important for leafy crops. Potassium deficiency produces a spotted, curled, or burned appearance to leaves and lowers crop yields. Potassium fertilizers are applied in the following forms potassium chloride, potassium sulfate, potassium nitrate, and wood ash. 

Control of renin release from the Icidney is influenced by (1) specialized cells in the distal convoluted tubules called the macula densa function as cliemoreceptors for the concentration of sodium delivered to the distal tubules (2) juxtaglomerular cells functioning as mini pressure transducers sense the renal perfusion pressure in the kidney (3) the sympathetic nervous system that feeds the kidney and catecholamine release and (4) humoral factors such as potassium, atrial natriuretic peptides, and angiotensin II. All of these influences are involved in the normal control of salt and water balance and with diseases of the kidney. Secondary... 

If potassium becomes too deficient, changes in body chemistry, water balance, and possibly blood pressure will take place. The sodium content of the heart and other muscle tissue will increase. The heart rate will diminish, and there will be generalized weakness. Reflexes are poor, brain function is impaired, and muscles become soft and unresponsive. Sterility and kidney problems appear. If extreme dehydration is involved, potassium can become drained and proteins break down. The risk of stroke is increased. As I have pointed out before, extreme potassium deficiency can be fatal. If ever you have reason to believe you are low or deficient in potassium. Table 3.2 should be helpful to you.

Potassium appears to perform many of the same functions inside the cell that sodium performs in the plasma and interstitial fluid. Potassium, in various ways 1) regulates the maintenance of the osmotic equilibrium of body fluids 2) acts as an available base to neutralize acids 3) maintains an ionic balance between potassium, sodium, calcium, and magnesium, which in turn affects capillary and cell functions and the excitability of nerves and muscles 4) maintains correct water balance in the body and 5) acts as a cofactor in several enzyme systems, including those used for energy transfer and utilization, protein synthesis, and carbohydrate metabolism (Oberleas et al.

Sodium (Na ), potassium (K ), and chloride (Cl ) are the major electrolytes (ions) in the body. They establish ion gradients across membranes, maintain water balance, and neutralize positive and negative charges on proteins and other molecules.

Sea lettuces which draw from the sea contain wealth of mineral elements (Table 5.4). Calcium, one of the most important minerals essential for human body, is accumulated in sea lettuces at a higher level compared with milk, brown rice, spinach, peanuts, and lentils (MacArtain et ah, 2007). Calcium contents in Ulva lactuca, Ulva reticulata, Ulva fasciata were 32.5, 147, and 0.47 mg/100 g edible portion, respectively. Moreover, potassium and sodium are known as electrolytes because their ability to dissociate into positively and negatively charged ions when dissolved in water. Potassium is the major cation of intracellular fluid. Together with sodium, it maintains normal water balance. In addition, potassium also promotes cellular growth and maintains normal blood pressure. Potential source of potassium is Ulva reticulata, which contains 1540 mg potassium per 100 g edible portion (Ratana-arpom and Chirapart, 2006).

The electrolytes sodium, potassium, calcium, and magnesium occur in the body fluids (aqueous solutions) as cations, partly bound to proteins or other organic components, and they are in equilibrium with the anions. In relation to the water balance the main function of the ions is to maintain osmotic pressure. In the extracellular space the most important cation is sodium (anion chloride), in the intracellular space the main cation is potassium (anion bicarbonate). The regulation... 

Abnormal electrolyte concentrations in blood serum can indicate the presence of disease. The ion concentrations that vary as a result of disease are Na+, K+, Cl , and HCO J. Sodium ion concentration is a good indicator of the water balance between blood and tissue cells. Unusual potassium ion levels can indicate kidney or gastrointestinal problems. Chloride ion is the anion that balances the positive charge of the sodium ion in the fluid outside the cells. It also diffuses into a cell to maintain normal electrolyte balance when hydrogen carbonate ions diffuse out of the cell into the blood. Table IB shows medical conditions associated with electrolyte imbalances. 

There are three major tubular functions to be recognised (1) salt and water balance, (2) potassium and acid/base homeostasis, and (3) calcium and phosphorus balance. 

Relatively high levels of potassium are utilized by growing plants. Potassium activates some enzymes and plays a role in the water balance in plants. It is also essential for some carbohydrate transformations. Crop yields are generally greatly reduced in potassium-deficient soils. The higher the productivity of the crop, the more potassium is removed from soil. When nitrogen fertilizers are added to soils to increase productivity, removal of potassium is enhanced. Therefore, potassium may become a limiting nutrient in soils heavily fertilized with other nutrients.
