Overview

A vitamin is an organic compound required as a nutrient in tiny amounts by an organism. A compound is called a vitamin when it cannot be synthesized in sufficient quantities by an organism, and must be obtained from the diet. Thus, the term is conditional both on the circumstances and the particular organism. For example, ascorbic acid functions as vitamin C for some animals but not others, and vitamins D and K are required in the human diet only in certain circumstances.

Vitamins are classified by their biological and chemical activity, not their structure. Thus, each "vitamin" actually refers to a number of vitamer compounds, which form a set of distinct chemical compounds that show the biological activity of a particular vitamin. Such a set of chemicals are grouped under an alphabetized vitamin "generic descriptor" title, such as "vitamin A," which (for example) includes retinal, retinol, and many carotenoids. Vitamers are often inter-convertible in the body. The term vitamin does not include other essential nutrients such as dietary minerals, essential fatty acids, or essential amino acids, nor does it encompass the large number of other nutrients that promote health but are otherwise required less often.

Increasing Organ Donation Awareness

My wife had a kidney transplant when she was only 17 years old. Yes, that could happen to anyone at any age. Thanks to its successful transplant, she was in a position consistent with their normal lives. There are nearly 100,000 patients in the U.S. currently waiting for organ transplants and chronic kidney disease accounts for the majority on the waiting list. A person could be either an organ from a living donor or a cadaver. Living donors in many cases are usually relatives or close friends. While cadaveric donors come from people who are interested in donating their organs while they are alive.

A recent Gallup poll indicated that the majority of Americans are now open for organ transplants. But only 20 percent of the year 20000 to 25000 brain deaths in this country to donate organs. This happens because some of the people who want to donate their organs do not share their wishes with their families and friends or a donor card. Many fear that organ donation is against their religion, when in fact most religions support this. It is the awareness of organ donation in general is absolutely necessary.

One of the things that my wife and I like to do to raise awareness is to participate in kidney hikes and other activities. On Sunday, 19 October, we went to New York City for the kidney walk from the National Kidney Foundation. The hike began at about 10:30 clock from South Street Seaport and went around the historic Battery Park It was a beautiful day and there were many people with their families and friends. We had an explosion and were able to spot Alonzo Mourning, professional basketball players from the NBA's Miami Heat. Alonzo was last known, for a kidney transplant and a year later won his first NBA championship. He was there signing his new book, "Resilience: The Faith Focus, Triumph" with Dan Wetzel.
