When you see a "K" on the periodic table, you probably know that it is the symbol for potassium. But if you mistook it for krypton, which is "Kr," you're not far off -- the mineral may indeed make you feel like Superman. Potassium is an important building block of the metabolism and of the body. Be careful, however, as the mineral is so potent that serious health risks are posed to people who consume too much.
Potassium and Amino Acids
DNA undergoes a process known as translation when it becomes RNA, but it needs the help of proteins to do so. The five Nitrogenous bases -- Thymine, Cytosine, Guanine, Adenine, and Uracil -- can then become one of 20 different types of proteins. But the DNA process of transcription and/or replication cannot happen without potassium to assist with protein synthesis, making the mineral highly important to your body's functioning.
Potassium and pH
The acidity or basicity of a substance can be measured on the pH scale, with a result of less than 7 being more acidic and a result of more than 7 being more basic. Your body does a decent job of regulating your pH levels, but it is greatly assisted by potassium. In a study conducted in the "Journal of Daily Science," the sodium content of plasma in the subject was greatly increased by a dosage of plasma potassium while the pH levels decreased accordingly. Extreme dosages of potassium could pose health risks, however, according to the study.
Potassium and Strength
Notice how protein and potassium were inextricably linked in the DNA replication process and it shouldn't come as a surprise that they also work in tandem for strength building. Protein allows your body to grow bigger and stronger while Potassium keeps your blood sugar elevated and your appetite healthy. David Zieve, M.D., recommends 4.7 g of potassium per day for adults, 3.8 g per day for children from ages 4 to 8 years, 3 g for children ages 1 to 3 years, and 0.7 g per day or less for infants younger than 1 year old.
Potassium and the Heart
If you have wondered why your heart beats, it's because of electrical activity. If you have ever wondered how it stays in control, it's because of potassium. Your heart knows to take in oxygen and pump out blood when it receives an electrical signal from your nerves. And thanks to the monitoring properties of potassium, these electrical signals occur no more and no less than they need too, unless you suffer from heart problems. The electrolyte content of potassium can conduct the electrical signals, thus regulating your heart function.
Other Functions
The electrolytes in potassium not only regulate your heart, but they ensure a proper restoration of other essential fluids and vitamins in your body as well. According to the University of Maryland's Medical Center, potassium is crucial for maintaining digestive and muscular function and it can even help to prevent strokes and high blood pressure. The Center also warns you not to begin consuming potassium supplements without talking to a doctor. If you have hyperakelmia or kidney problems, do not take them under any circumstance.
