It is also used for preventing the transmission of HIV from mothers to children. Other uses for lauric acid include treatment of bronchitis, gonorrhea, yeast infections, chlamydia, intestinal infections caused by a parasite called Giardia lamblia, and ringworm. In foods, lauric acid is used as a vegetable shortening.
Vit E. =It is an antioxidant. That means it protects body tissue from damage which caused by substances called free radicals. Free radicals can harm cells, tissues, and organs. They are believed to play a role in certain conditions related to aging.
In a similar experiment, the combination of 11.622g of Lauric acid and 2.252g of an unknown acid caused the new freezing point of Lauric acid solution to be 37.0 ºC. Use this data to calculate the molar mass of the unknown acid. For the credit show, all calculations used to determine the molar mass.
