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).
They (skunk spray and asparagus urine) seem to be both caused by sulphur-containing chemicals, called thiols. Many thiols have a repulsive odour. The human nose can detect the thiols in skunk spray at levels as low as 10 parts per billion (that's equivalent to 10 seconds in 32 years). But some thiols smell fine.
