Semen

...sponsible for the smell and flavor of semen. These alkaline bases counteract the acidic environment of the vaginal canal (which is harmful to sperm), and protect DNA inside the sperm from acidic denaturation. Salts and metal ions in the semen help to create a more hospitable enviroment for the sperm in the ...

RNA

...; but at the same time, it makes RNA sensitive to alkaline hydrolysis , to which DNA is not. The other major difference between RNA and DNA is that RNA is almost exclusively found in the single-stranded form (an exception being the genetic material of some kinds of viruses ). RNA molecules often fold into ...

Kidney

...n the other hand, becomes either acidic at pH 5 or alkaline at pH 8. Sodium ions are controlled in a homeostatic process involving aldosterone which increases sodium ion absorption in the convoluted tubule. Any rise or drop in blood osmotic pressure due to a lack or excess of water is detected by the hyp...
