Introduction: Functional groups refer to specific group of atoms or bonds in a compound and have characteristic properties. They impart charge to the hydrocarbon chain; for example, alcohols,
Answer to Problem 1E
Correct answer: An amino group or imino group gives a positive charge to a molecule, and a carboxylate or phosphoryl group gives a negative charge to a molecule.
Explanation of Solution
Functional groups are the reactive regions of molecules that are functionalized with these specific groups. The common functional groups are alcohols (-OH), carbonyls (C=O), carboxylic acids (-COOH), amines (-NH2), and esters (-COOR). They are classified on the basis of their charge and polarity.
The functional groups associated with
The functional groups that impart a negative charge to the biomolecules are carboxylate group, alcohol group, phosphoanhydride group, and phosphodiester linkages. They release H+ and impart a negative charge. These functional groups are present in most biomolecules such as carbohydrates, proteins, and
