Why are buffers so important to living systems?
What are some examples of buffer systems that occur in the human body?
Different pH's will cause molecules to gain and loose electrons and protons
(ionize). If proteins are not kept at the proper pH they will not function
properly by assuming nonfunctional shapes because of changing ionic states.
pH is probably the most important single thing the body regulates since it
will affect so many others. Proteins are a major buffer; sodium bicarbonate
and phosphate are others.
