• Relative reactivities of the amino radical with several organic compounds have been reported, but the absolute rate constants for such reactions remain unknown. (wikipedia.org)
  • Researchers at the Max Planck institute in Germany have discovered large quantities of organic molecules at the center of the Milky Way that resemble life-bearing amino acids in their complexity. (extremetech.com)
  • Due to the two charges on zwitterions, there is a much stronger intermolecular attraction between the ions, raising the melting point of an amino acid far above the melting point of organic compounds with similar molecular mass and numbers of electrons . (conservapedia.com)
  • Much more important are the other lab values such as lactate, pyruvate, serum amino acids, urine organic acids, and then if needed the muscle biopsy with electron transport and oxidative phosphorylation determination and electron microscopy of the muscle. (medhelp.org)
  • In 2000, an experiment showed that when circularly polarised ultraviolet light of a particular handedness was shone on an equal mix of right- and left-handed amino acids, it produced an excess of 2.5% by preferentially disintegrating one type. (newscientist.com)
  • A great many such matrices exist: an incomplete listing available from the AAIndex database ( K awashima and K anehisa 2000 ) includes 83 matrices of pairwise amino acid similarity or distance and 494 indices of amino acid properties. (genetics.org)
  • Likewise, a bias favoring AT (or GC) base pairs would affect the relative rates of Glu → Gly (GAR → GGR) vs. Glu → Val (GAR → GTR), and such effects seem to have played an important role in the evolution of amino acid composition ( S inger and H ickey 2000 ). (genetics.org)
  • Other examples of such amino acids include carnitine, which is concerned in fatty acid transport within a cell, as well as ornithine and citrulline, both of which are key components in the body's urea cycle. (fsu.edu)
  • Excess dietary amino acids are neither stored for future use nor excreted. (conservapedia.com)
  • We are beginning to understand how critical the balance of dietary amino acids is to the control of appetite, health, and aging," noted Stephen Simpson, PhD, academic director and professor, School of Life and Environmental Sciences of the University of Sydney's Charles Perkins Centre.

  • The resulting cyclic formation having the characteristic NCNC group in it, would correspond to abnormal amino acids which would represent the primary characteristic formation of the cancerous condition. (chestofbooks.com)
  • Unless the values are extremely outside the range of normal, or are in a particular pattern, we usually do not call abnormal amino acids values in the urine. (medhelp.org)
  • Part of the difficulty in determining our need for individual amino acids involves the interconversion of amino acids that is constantly taking place in our body. (whfoods.org)
