Carbon and Organic Chemistry – Chemistry
My optimism for extending healthy human life went up a few notches in 2009 when the results of the testing of rapamycin came out. This was a major event in anti-aging research that could have implications for longevity and rejuvenation. Rapamycin is the first pharmaceutical known to extend healthy life in mice. Mice are genetically similar to humans, so what is good for the mouse might be good for the man (and woman). This study came about as a result of happenstance. Two chance events lead to a discovery that may change the face of old age.
The properties of organic compounds differ from those of inorganic compounds. Organic compounds have * low melting points * low boiling points * soluble organic solvents rather than water * poor electrical conductivity. Organic reactions are usually slow and produce low yields of product because of the many side reactions that can occur.
Although, there are millions of known organic compounds, the elements they contain are relatively few. Besides, carbon and hydrogen, there is oxygen, nitrogen, sulfur, phosphorus and the halogens. The variety of organic compounds is due to the many different arrangements, or structures, that are possible. The chemical and physical properties of these compounds are related to the structures of their molecules. Thus, the key to understanding organic chemistry is an understanding molecular structure and chemical bonding.
Carbon Remember, carbon has four valence electrons and can obtain a stable configuration by forming four covalent bonds. Carbon can form single, double or triple bonds and only a few elements can do this. Also, carbon is unique in that it bonds easily with other carbon atoms, while other elements rarely bond with like atoms. Thus, carbon can form long chains, branched chains, rings and rings with chains for a vast variety of compounds.
Dr. Anthony Atala – Dr. Atala heads the Wake Forest Institute for Regenerative Medicine and is another leader in organ replacement, he has had great success with laboratory grown bladders. Continuous-Flow Ventricular Assist Devices – these tiny 3-ounce devices can be surgically attached alongside the heart. For patients waiting for a heart transplant these can be lifesaving, they quietly and effectively take over the pumping ability of the heart. In the future, they may eliminate the need for some transplants.
When you look at quality of life I would add 2 more. They may not extend life but for anyone who might be thinking, “I’m so miserable I want to die,” they sure could make it more pleasant! They are: Tooth implants in one day, replacing surgery and long recovery times and Lyric hearing aids from InSound Medical, the first hearing aid you can wear for months straight without surgical implantation. The increase in attention and interest in research related to extending healthspan and lifespan has made this year significant. There is lots more to come in 2010 and I will be watching it closely.
