Blood clots can present as red tender lines on the legs or they can develop silently and grow extensively in the deep veins of the leg before being discovered. They are suspected by the physician when there is swelling or pain in just one leg that is not explainable by any other cause such as an injury or other event.
Thiol with a blue-highlighted sulfhydryl group. In organic chemistry, a thiol (/ËÎ¸aÉªËÉËl/ , /ËÎ¸aÉªËÉl/) is an organosulfur compound that contains a carbon-bonded sulfhydryl (âCâSH or RâSH) group (where R represents an alkane, alkene, or other carbon-containing group of atoms).
Thiomersal features mercury (II) with a coordination number 2, i.e. two ligands are attached to Hg, the thiolate and the ethyl group. The carboxylate group is not coordinated, but confers solubility in water. Like other two-coordinate Hg(II) compounds, the coordination geometry of Hg is linear, with a 180Â° S-Hg-C angle. Typically, organomercury thiolate compounds are prepared from organomercury chlorides.
