The word "alkali" is derived from Arabic al qalīy (or alkali),[1] meaning the calcined ashes (see calcination), referring to the original source of alkaline substances. A water-extract of burned plant ashes, called potash and composed mostly of potassium carbonate, was mildly basic. After heating this substance with calcium hydroxide (slaked lime), a far more strongly basic substance known as caustic potash (potassium hydroxide) was produced. Caustic potash was traditionally used in conjunction with animal fats to produce soft soaps, one of the caustic processes that rendered soaps from fats in the process of saponification, one known since antiquity. Plant potash lent the name to the element potassium, which was first derived from caustic potash, and also gave potassium its chemical symbol K (from the German name Kalium), which ultimately derived from alkali.
Soils with pH values that are higher than 7.3 are usually defined as being alkaline. These soils can occur naturally, due to the presence of alkali salts. Although many plants do prefer slightly basic soil (including vegetables like cabbage and fodder like buffalo grass), most plants prefer a mildly acidic soil (with pHs between 6.0 and 6.8), and alkaline soils can cause problems.[1]

Alkaline water must contain alkaline minerals and negative oxidation-reduction potential (ORP). ORP is the ability of water to act as a pro- or antioxidant. The more negative the ORP value, the more anti-oxidizing it is.
This technique uses a product called an ionizer to raise the pH of regular water. Makers of ionizers say that electricity is used to separate molecules in the water that are more acidic or alkaline. The acidic water is then funneled out.
There are also some other safety concerns to drinking ionized alkaline water. When you drink it regularly, there is a greater chance of developing hyperkalemia, particularly if the pH of the water is greater than 9.8.
Other concerns include that it could hinder growth, deplete minerals and vitamins from the body, and interfere with nutrient absorption. Additionally, it might harm your mucosal lining and result in excessive thirst.
However, you should use caution with artificial alkaline water, which likely contains fewer good minerals than its high pH would have you believe and may contain contaminants. More research is needed to determine its benefits.

Fixed acids are excreted in the urine, whereas volatile acids are excreted by the lungs. One volatile acid is carbonic acid, which is formed by the lungs as part of your breathing process. This increases the acidity of your blood.
The kidneys, meanwhile, are reabsorbing bicarbonate, which comes from the carbonic acid in the blood. This entire process resists change to the pH to allow you to stay in the necessary pH range for life.
Keep in mind that recent scientific evidence suggests no link between dietary acid and bone health. In fact, a high protein, acid-forming diet may be linked to better bone health due to increased calcium retention and activation of IGF-1 hormone.
However, this research does not reflect blood acidity. It is also unclear if dietary acid load definitively causes cancer. In fact, experiments have also successfully grown cancer cells in an alkaline environment.
Keep in mind that our remote ancestors lived in vastly different climates with access to diverse foods. In fact, acid-forming diets were more common as people moved further north of the equator, away from the tropics.
An alkaline phosphatase (ALP) test measures the amount of ALP in your blood. ALP is an enzyme found in many parts of your body. Each part of your body produces a different type of ALP. Most ALP is found in your liver, bones, kidneys, and digestive system.
Abnormal levels of ALP in your blood may be a sign of a wide range of health conditions, including liver disease, bone disorders, and chronic kidney disease. But an alkaline phosphatase test alone can't identify the source of ALP in your blood, so other tests are usually needed to make a diagnosis.
Your health care provider may order an alkaline phosphatase test as part of a routine checkup. Many conditions may affect ALP levels, so the test is often done with other blood tests. These other tests include a comprehensive metabolic panel (CMP) or liver function tests that check how well your liver is working.
An alkaline phosphatase test is a type of blood test. During the test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
Preparations for an alkaline phosphatase test depend on the lab doing the test. Some labs require you to fast (not eat or drink) for 6 to 12 hours before the test. Also, the ALP test is usually ordered with other blood tests. You usually need to fast for several hours before these tests. Your provider will let you know if there are any special instructions to follow.
High alkaline phosphatase (ALP) levels may be a sign of a liver problem or a bone disorder. Liver problems and bone disorders cause different types of ALP. But your test results can't tell which type of ALP is high.
If alkaline phosphatase levels are high and the results of liver tests are normal, the problem may be a bone disorder, such as Paget's disease of bone. This disease makes your bones unusually large and weak, causing them to break more easily.
It's possible to have higher than normal levels of ALP and not have a medical condition that needs treatment. Your provider will consider your symptoms, medical history, and other test results to make a diagnosis.
Low levels of ALP are less common. They may be a sign of a lack of zinc, malnutrition, pernicious anemia, thyroid disease, Wilson disease or hypophosphatasia, a rare genetic disease that affects bones and teeth.
Many things can affect ALP levels. Pregnancy can cause higher than normal ALP levels. Children and teens may have high levels of ALP because their bones are growing. Birth control pills and certain medicines may lower ALP levels, while other medicines can cause the levels to increase. Even eating a fatty meal before an alkaline phosphatase test may also cause a small increase in ALP.

Alkaline phosphatases (ALPs) are a group of isoenzymes located on the outer layer of the cell membrane. They catalyze the hydrolysis of organic phosphate esters found in the extracellular space. Zinc and magnesium are essential cofactors of this enzyme. Despite the diverse tissue distribution and varying physiochemical properties of ALPs, they are classified as true isoenzymes due to their shared ability to catalyze the same reaction.
ALP is found in the cytosol of liver cells and the canalicular membrane of hepatocytes.[1] ALP is found in decreasing concentrations in various organs such as the placenta, ileal mucosa, kidney, bone, and liver. Over 80% of the ALP in serum originates from the liver and bone, with minor contributions from the intestine. Although ALPs are present in various tissues throughout the body, their precise physiological function remains elusive.[2]
