1. What is Alpha GPC Powder?
Alpha GPC 99% Powder is a water-soluble small molecule that normally exists in the human body, and is the biosynthetic precursor of acetylcholine, an important neurotransmitter. The most important function of Alpha GPC is that the choline produced by it is a water-soluble vitamin B group, which has an important effect on the brain and nervous system.
2.Main Function
*Strengthen memory
*Enhance cognitive ability
*Improve learning ability
Alpha-GPC has the effect of helping to delay, stop or reverse Alzheimer's and dementia and other aging diseases that have deteriorated cognitive ability.
Alpha GPC can also promote the secretion of human growth hormone in the elderly.High release of human growth hormone can keep the elderly strong and healthy.
3.Application
Alpha GPC 99% Powder is waidely used for health products of cognitive disorders such Alzheimer's disease and other various kinds of dementia, stroke, and 'mini stroke' (transient ischemic attack, TIA). It is also used as raw material of nutritional supplements or Food Additives by improving memory, thinking skills and learning skills and used as cosmetic additives for skin conditioning.
4.Method of Analysis
Specific Rotation- The reference Specific Rotation in a monograph signifies that specific rotation is to be calculated from observed optical rotations in the Test solution obtained as directed therein. Unless otherwise directed, measurements of optical rotation are made at 589 nm at 25°. Where a photoelectric polarimeter is used, a single measurement, corrected for the solvent blank, is made. Where a visual polarimeter is employed, the average of no fewer than five determinations, corrected for the reading of the same tube with a solvent blank, is used. Temperature, which applies to the solution or the liquid under test, should be maintained within 0.5° of the stated value. Use the same cell for sample and blank. Maintain the same angular orientation of the cell in each reading. Place the cell so that the light passes through it in the same direction each time. Unless otherwise specified, specific rotation is calculated on the dried basis where Loss on drying is specified in the monograph or on the anhydrous basis where Water is specified.
Optical rotation of solutions should be determined within 30 minutes of preparation. In the case of substances known to undergo racemization or mutarotation, care should be taken to standardize the time between adding the solute to the Solvent and introduction of the solution into the polarimeter tube.
