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).
Organosulfur Compounds. Both thiols and mercaptans are organosulfur compounds that contain a sulfur-hydrogen bond, analogous to the hydroxyl group (-OH) of alcohol. The chemical differences between oxygen and sulfur give the group its unique properties. Not only is the -SH group an acid, but it is also a nucleophile for attacks on saturated carbon.
