Polar groups in lipids help to impart stability and solubility. In proteins, polar groups are crucial for forming hydrogen bonds that contribute to the protein's structure and function. Nucleic acids contain both polar and nonpolar groups, with the polar groups playing a role in base pairing specificity in DNA and RNA, while nonpolar groups contribute to the overall stability of the double helix structure.
