Thiol

In organic chemistry, a thiol (/ˈθaɪˌɔːl/, /ˈθaɪˌɒl/) is an organosulfur compound that contains a carbon-bonded sulfhydryl (–C–SH or R–SH) group (where R represents an alkane, alkene, or other carbon-containing group of atoms). Thiols are the sulfur analogue of alcohols (that is, sulfur takes the place of oxygen in the hydroxyl group of an alcohol), and the word is a portmanteau of "thion" + "alcohol," with the first word deriving from Greek θεῖον ("thion") = "sulfur." The –SH functional group itself is referred to as either a thiol group or a sulfhydryl group.

Many thiols have strong odors resembling that of garlic. Thiols are used as odorants to assist in the detection of natural gas (which in pure form is odorless), and the "smell of natural gas" is due to the smell of the thiol used as the odorant.

Thiols are often referred to as mercaptans. The term mercaptan /mərˈkæptæn/ was introduced in 1832 by William Christopher Zeise and is derived from the Latin mercurium captans (capturing mercury) because the thiolate group bonds very strongly with mercury compounds. Thiols react with mercury to form mercaptides.

You Know He Never Loved You

by: Thalia

All this time I've been trying hard to hear you
To understand you and to console you
I know your life, and it's never been that simple
But now's the time to close the circle
To start over again it's something scary
I know those bruises in your heart are there forever
But now's the time to start again stronger than ever
And show the world in your own way that you are never gonna go through this again
You know he never loved you, you know he never wanted you
He stabbed you in the back and he broke your heart in half
But that will make you stronger, no suffering, no longer
You learned from your mistakes and there ain't no coming back
Now go enjoy your life and you're gonna laugh so hard
You're never gonna cry once again for a guy
You know he never loved you, you know he never wanted you
But at least you learned somehow
But if now you cannot stop thinking of his love
And his kisses, and his caresses
If in the night can't sleep because you miss him
Just remember the thing you've been through
To start over again it's something scary
I know those bruises in your heart are there forever
But now's the time to start again stronger than ever
And show the world in your own way that you are never gonna go through this again
You know he never loved you, you know he never wanted you
He stabbed you in the back and he broke your heart in half
But that will make you stronger, no suffering, no longer
You learned from your mistakes and there ain't no coming back
Now go enjoy your life and you're gonna laugh so hard
You're never gonna cry once again for a guy
You know he never loved you, you know he never wanted you
But at least you learned somehow
But now's the time to start again stronger than ever
And show the world in your own way that you are never gonna go through this again
You know he never loved you, you know he never wanted you
He stabbed you in the back and he broke your heart in half
But that will make you stronger, no suffering, no longer
You learned from your mistakes and there ain't no coming back
Now go enjoy your life and you're gonna laugh so hard
You're never gonna cry once again for a guy
You know he never loved you, you know he never wanted you
