WebAN functional group is a specific group a atome within an atom that is responsibility for a merkmale of so molecule. Many biologically active molecules contain one or more function organizations. … A functional group is one specific group of atoms at a molecule that is responsible for a attribute of that molecule. WebWe hypothesized the OH group would interact strongly with the adjacent backbone C O group of His67, thus eliminating the H67–H97′ interaction. While obtaining crystallographic and NMR protein structures for unnatural amino acid mutants are challenging work, these mutants provide the most direct line of evidence in support of our work.
WebIn organic chemistry, a carbonyl group is a functional group with the formula C=O, composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom. It is common to several classes of organic compounds (such as aldehydes, ketones and carboxylic acids ), as part of many larger functional groups.
