Adrenaline: When the Heat Is On
We, The Last Minute, chose the subject of adrenaline because we thought it would make an exciting project (actually we just found more information on adrenaline than on our original topic). In order to locate sites of interest we scanned through thousands of skateboard junkie and other crap sites to find the five or six which actually mattered. We also checked several chemistry sites for the physical information on adrenaline's chemistry (which was easier once we realized that adrenaline was also called epinephrine…duh).
Epinephrine and norepinephrine, also called ADRENALINE and NORADRENALINE, are two separate but related hormones secreted by the medulla of the adrenal glands. They are also produced at the ends of sympathetic nerve fibers, where they serve as chemical mediators for conveying the nerve impulses to effector organs. Chemically, the two compounds differ only slightly; and they exert similar pharmacological actions, which resemble the effects of stimulation of the sympathetic nervous system. They are, therefore, classified as sympathomimetic agents. The active secretion of the adrenal medulla contains approximately 80 percent epinephrine and 20 percent norepinephrine; but this proportion is reversed in the sympathetic nerves, which contain predominantly norepinephrine. But enough of this…here are the sites:
The first site we would like to present is THIS SITE , which consists of an excellent article discussing the synthesis, structure, and function of adrenaline.
Wanna see a 3-D, fully maneuverable model of adrenaline? Then CLICK HERE! (Clicking on this link opens a VRML-Virtual Reality Model File. If your web browser doesn't support this, you may have to download one. HERE is a link to the download site for the VRML browser I (Blake) use. You can also get them from Microsoft and Netscape.)
By now, I'll bet you're saying, "You know, I'd really like to see some of the structure details of adrenaline." Well here today, you're in luck…CLICK HERE to see a chart.
THIS SITE links you to a short article about John Jacob Abel, the scientist who isolated adrenaline.
And just in case you were wondering about the phenylalanine to adrenaline synthesis pathway (and the enzymes involved), you can CLICK HERE to be enlightened on that subject.
If you're interested in some of the medical and health issues involving adrenaline, you can CLICK HERE to read an article about the use of adrenaline in cases of ventricular fibrillation. You can also FOLLOW THIS LINK to the Adrenaline Addiction Recovery Home Page. "But how do I know if I have an adrenaline addiction," you say? Well, you can CLICK HERE to view the Top Ten Signs of Being an Adrenaline Addict, or LOOK UP adrenaline in the Distinctionary to find out the difference between it and passion.
Lastly, if you have an adrenaline addiction (and proud of it), you can visit THIS SITE , The Site For Adrenaline Sports Enthusiasts, to feed your addiction.
