Some textbooks assert that histidine can provide buffering capacity at the physiological pH of 7.4.

a) Is this assertion correct?

b) What are the unprotonated (base) and protonated (acid) forms of histidine that would contribute to the buffering?

c) Is there another amino acid that could potentially provide buffering at physiological pH? If so, which one and what are the unprotonated and protonated forms of this amino acid that would ocntribute to the buffering?

You wish to have $200,000 at the end of twenty years. In the last five years, you withdraw $1,000 annually at a rate of 3.8% compounded quarterly. During the middle ten years, you contribute $500 monthly at a rate of 2.8% compounded semi-annually. Given this information, determine the initial deposit that has to be made at the start of the first five years at a rate of 4% compounded monthly.

Suppose that you just turned 25 years old and that you wish to receive an annual annuity of $63,282 for 30 years (end of each year age 65-95). How much would you have to contribute annually at the end of each year ages 25-60 , if you then let the funds vest until age 65 with no further contributions? Your EAR is 8.7%.
