Question

And also is the amino Cysteine in the functional group of Sulfhydryls?

Answer 1

A thiol is a compound that contains the functional group composed of a sulfur atom and a hydrogen atom (-SH). Being the sulfur analogue of an alcohol group (-OH), this functional group is referred to either as a thiol group or a sulfhydryl group. Thiols are also often referred to as mercaptans. So, to answer your question, yes, cysteine is an amino acid that contains a sulfhydryl group. Here's it's structure...

HS-CH2CH(NH2)-COOH...
