Are the following questions true or false?
a) A carboxylic acid favours the ion form (R-COO-) and its pH is higher than its pKa.
b) In most membranes, the polar heads of the phospholipids align towards the middle of the membrane.
c) All proteins contain either an alpha helix or beta sheets.
a) FALSE. Some carboxylic acids have such pKa values that equal or higher pH value would give acidic medium. For example, acetic acid has pKa of 4.7. When pH equals to 4.7, the ...
