Amino acids are the building blocks of proteins and have a common structure consisting of a central carbon atom (the alpha carbon) to which four groups are attached:
1. **Amino group (-NH2)**: This functional group is the same for all amino acids and contains a nitrogen atom bonded to two hydrogen atoms.
2. **Carboxyl group (-COOH)**: This group is also found in all amino acids and contains a carbon atom doubly bonded to an oxygen atom and singly bonded to a hydroxyl group (-OH).
3. **Hydrogen atom (H)**: This is a single hydrogen atom attached to the central carbon.
4. **R group or side chain (variable group)**: This is the group that differentiates one amino acid from another. The R group can vary in size, shape, charge, hydrophobicity, and reactivity. There are 20 standard amino acids, and the differences in their R groups lead to the diverse properties of amino acids.
The diversity of the R groups allows amino acids to exhibit a wide range of chemical behaviors, influencing protein structure, stability, and function. Based on the characteristics of the R groups, amino acids can be classified into categories such as nonpolar, polar, charged (acidic or basic), and aromatic, which also affects how they interact with each other and with other molecules.
