Functional Groups
Question | Answer |
---|---|
What is the chemical formula for an amino group? | NH₂ |
What is the chemical formula for a phosphate group? | PO₄ |
What is the chemical formula for a hydroxyl group? | OH- |
What is the chemical formula for a carboxyl group? | O=C-O-H |
Which functional group is a characteristic of alcohols? | OH-, a hydroxyl group |
Which functional group behaves as a base? | NH₂; the electronegativity of Nitrogen means that amino groups tend to pick up H+ |
What is the chemical formula of a carbonyl group? | C=O |
Which functional group is a characteristic of thiols? | -SH, sulfhydryl |
Which functional group plays a major role in energy transfer? | PO₄ , a component of ATP |
Which functional group behaves as an acid? | Carboxyl group; the two electronegative oxygens pull electrons from the Hydrogen ion. Due to that weakened bond, they tend to dissociate. |
What is the chemical formula of sulfhydryl? | SH |
