Calcium Chloride is used in concrete mixes to help speed up the initial setting, but chloride ions lead to corrosion of steel rebar, so it should not be used in reinforced concrete.[12] The anhydrous form of calcium chloride may also be used for this purpose and can provide a measure of the moisture in concrete.[13]
Calcium Chloride is used in swimming pool water as a pH buffer and to adjust the calcium hardness of the water.
Calcium Chloride is included as an additive in plastics and in fire extinguishers, in wastewater treatment as a drainage aid, in blast furnaces as an additive to control scaffolding (clumping and adhesion of materials that prevent the furnace charge from descending), and in fabric softener as a thinner.

Useful Information of Taurine




Product name:Taurine
CAS:107-35-7
Molecular Formula:C2H7NO3S
Formula Weight:125.15
Description of Taurine:
Taurine, often referred to as an amino acid, is not part of the human body’s structural proteins. Instead, taurine remains free in the tissues and bloodstream. In fact, taurine is one of the most abundant free amino-acid-like compounds found in the heart, the skeletal muscles and the nervous system.
Taurine is possibly best known as a health supplement, and is used in a variety of products. Bodybuilders take supplements of taurine coupled with creatine which may help in reducing muscle fatigue and soreness. Energy drinks, which are becoming hugely popular, especially among the teen and young adult set, often list taurine as one of its main supplemental ingredients. Drinks like Monster™ and Rockstar™ both contain up to 2000 mg of taurine, which is within daily suggested doses of 50 mg to 3 grams.

Useful Information of Ascorbic Acid




Product name:Ascorbic Acid
CAS:50-81-7
Molecular Formula:C6H8O6
Molecular Weight:176.12
Description of Ascorbic Acid:
Why is Ascorbic Acid used instead of natural vitamin C?
The C vitamin is a naturally occurring nutrient found in countless fruits and vegetables. However the problem is that when it is heated, the vitamin breakdown and becomes useless. So if you heat up your food, it’s gone. This really poses a problem when it comes to liquids like orange juice. Pasteurization (boiling to kill off bacteria) is required for virtually every beverage sold today in the United States.
Ascorbic Acid was invented as a synthetic version to replace the natural form which is destroyed by heat.  So when you drink that glass of orange juice in the morning, you aren’t actually consuming natural vitamin C. Rather, you are consuming synthetic ascorbic acid which was added to replace the original.

Information of Heparin Sodium




Product name:Heparin Sodium
Description of Heparin Sodium:
Heparin Sodium, is a heterogenous group of straight-chain anionic mucopolysaccharides, called glycosamino-glycans having anticoagulant properties. Although others may be present, the main sugars occurring in heparin are:
(1) α- L-iduronic acid 2-sulfate,
(2) 2-deoxy-2-sulfamino-α-D-glucose-6-sulfate,
(3) β-D-glucuronic acid,
(4) 2-acetamido-2-deoxy-α-D-glucose,
(5) α-L-iduronic acid. These sugars are present in decreasing amounts, usually in the order (2) > (1) > (4) > (3) > (5), and are joined by glycosidic linkages, forming polymers of varying sizes. Heparin is strongly acidic because of its content of covalently linked sulfate and carboxylic acid groups. In heparin sodium, the acidic protons of the sulfate units are partially replaced by sodium ions. The potency is determined by a biological assay using a USP reference standard based on units of heparin activity per milligram.

Cholic Acid Introduction




Product name:Cholic Acid
CAS:81-25-4
Molecular Formula:C24H40O5
Molecular Weight:408.57 g/mol
Description of Cholic Acid:
Cholic Acid is manufactured from bovine bile (also known as "cattle bile" or "ox bile") at NZP in large volumes. It is a by-product of meat processing at veterinary certified companies. Ovine bile is also used. There is no synthetic and plant production source of cholic acid.
In nature, Cholic Acid is produced in the liver from cholesterol. The liver converts cholesterol into the conjugated salts of glycocholic and taurocholic acid which are excreted into the bile. Bile is released into the intestine where the bile salts emulsify fats and promote digestion. About 90% of the bile salts are reabsorbed by the intestine and pass back to the liver by a process referred to as enterohepatic circulation.
It is also available as the water soluble sodium salt.

How Does L-Tryptophan Work



Product name:L-Tryptophan
CAS:73-22-3
Molecular Formula:C11H12N2O2
Molecular Weight:204.23
Description of L-Tryptophan:
L-Tryptophan is naturally found in animal and plant proteins. L-tryptophan is considered an essential amino acid because our bodies can't make it. It is important for the development and functioning of many organs in the body. After absorbing L-tryptophan from food, our bodies convert it to 5-HTP (5-hyrdoxytryptophan), and then to serotonin. Serotonin is a hormone that transmits signals between nerve cells. It also causes blood vessels to narrow. Changes in the level of serotonin in the brain can alter mood.
