The role of functional groups in biological molecules

T he role of functional groups in biological molecules.

1. Functional groups are collections of atoms that attach the carbon skeleton of an organic molecule and confer specific properties..

Each type of organic molecule has its own specific type of functional group..

Functional groups in biological molecules play an important role in the formation of molecules like DNA, proteins, carbohydrates, and lipids..

Functional groups include: hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl..

Functional groups are groups of atoms that occur within organic molecules and confer specific chemical properties to those molecules..

When functional groups are shown, the organic molecule is sometimes denoted as “R.” Functional groups are found along the “carbon backbone” of macromolecules which is formed by chains and/or rings of carbon atoms with the occasional substitution of an element such as nitrogen or oxygen. Molecules with other elements in their carbon backbone are substituted hydrocarbons..

Molecules with other elements in their carbon backbone are substituted hydrocarbons. Each of the four types of macromolecules—proteins, lipids, carbohydrates, and nucleic acids—has its own characteristic set of functional groups that contributes greatly to its differing chemical properties and its function in living organisms..
