cholesterol molecular formula

Simple drug combination creates new neurons from neighboring cells

"The biggest problem for brain repair is that neurons don't regenerate after brain damage, because they don't divide," said Gong Chen, professor of biology and Verne M. Willaman Chair in Life Sciences at Penn State and leader of the research team. "In contrast, glial cells, which gather around damaged brain tissue, can proliferate after brain injury. I believe turning glial cells that are the neighbors of dead neurons into new neurons is the best way to restore lost neuronal functions."

Chen's team previously published research describing a sequence of nine small molecules that could directly convert human glial cells into neurons, but the large number of molecules and the specific sequence required for reprogramming the glial cells complicated the transition to a clinical treatment. In the current study, the team tested various numbers and combinations of molecules to identify a streamlined approach to the reprogramming of astrocytes, a type of glial cells, into neurons.

The cholesterol lowering drug Lipitor has the molecular formula C33FH35N2O5 (all #s should be subscripted) ?

What is its molecular mass?
What is the molecular mass in grams of one molecule of lipitor? If you take one pill that contains 15.0mg of lipitor, how many molecules have you ingested?


Just because there are a lot of atoms doesn't change how you do the calculation of the molecular mass:

C33: 33 moles of carbon atoms x 12.01 g/mole = 396.3 g of C
F(1): 1 mole of F atoms x 19.00 g / mole = 19.0 g of F
H35:
