  • Oxyrhine

    Having a sharp-pointed nose.  

  • Oxypurine

    An oxidation product of purine; includes hypoxanthine, xanthine, and uric acid.  

  • Oxyphonia

    An abnormally sharp or shrill pitch to the voice.  

  • Oxyosphresia

    Abnormal acuity of the sense of smell.  

  • Oxyosmia

    Unusual acuity of the sense of smell.  

  • Oxyntomodulin

    A 37-amino acid peptide secreted by the small intestine. It inhibits gastric acid secretion and reduces food intake.  

  • Oxymyoglobin

    The compound formed when myoglobin is exposed to oxygen.  

  • Oxyiodide

    A compound of iodine and oxygen with an element or radical.  

  • Oxyhemoglobin dissociation curve

    The mathematical relationship between the partial pressure of oxygen and the percentage of saturation of hemoglobin with oxygen (i.e., the proportion of oxyhemoglobin to reduced hemoglobin). Factors that favor a shift of the curve to the right, accelerating the decomposition of hemoglobin, are a rise in temperature and an increase of H ions that results…

  • Fractional oxyhemoglobin

    The ratio of the substance fraction of oxyhemoglobin to the substance fraction of all forms of hemoglobin. This quantity takes into account the effects of abnormal hemoglobins such as carboxyhemoglobin, methemoglobin, or sulfhemoglobin. Thus, in the presence of abnormal hemoglobins, the fractional oxyhemoglobin may be decreased while the oxygen saturation is normal.
