List and describe at least five substances that are intended to improve one's athletic performance

1.       Protein is a needed nutrient that everyone needs in order to function properly. Both athletes and sedentary individuals need to get sufficient amount of protein.

2.       Glucosamine has been used to treat osteoarthritis and aids to stimulate cartilage, though the outcomes of this are not persistent.

3.       Ribose is considered as a sugar. There is clear indication that affirms that an athletic performance benefit from ribose supplements.

4.       Creatine started off as a sport supplement but has initiated to work in elderly populations to relief the muscle mass. Athletes used creatine supplementation in order to expand frequent bouts of high-adrenaline workout.

5.       Glutamine is an amino acid which is categorized as a nourishing supplement. It helps the athletes make progress from exercise.

6.       B-Vitamins are important for the body to utilize appropriately, but there may be a link between the B-vitamins and performance among the high-level athletes.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
