Identify the major functional groups in an amino acid
- Functional groups attach to the carbon skeleton of the molecule. Common functional groups include: Methyl, Hydroxyl, Carbonyl, Carboxyl, Amino, Phosphate, and Sulfhydryl.
- Functional groups can be part of reactions and help in making proteins, carbohydrates, DNA, lipids, etc.
- The functional groups in an amino acid are the carboxyl and amino groups attached to the organic molecule (commonly represented with an R).
