The Protein Data Bank (PBD) provides a wealth of information on the structure, synthesis, and function of biological macromolecules at their education page. Content is suitable for students from middle school (advanced elementary) to college/university.
Primary Structure, Secondary Motifs, Tertiary Architecture And Quaternary Organization, Jannette Carey and Vanessa Hanley. Proteins are organized in a hierarchy of structures including primary structure (the amino acid sequence), secondary structure (a-helix and b-sheet), tertiary architecture (the specific atomic structure), and quaternary organization (arrangement of distinct polypeptide chains). Previously published in the Biophysics Textbook Online (BTOL).

The principles governing the assembly and energetics of proteins in biological membranes and the hydrophobicity of membrane proteins are outlined in a website maintained by the laboratory of Dr. Stephen White, University of California—Irvine.
Proteins, nucleic acids, and other biological molecules can self-assemble into complex, often large macromolecular structures such as filaments, chromosomes, and ribosomes. Information on select macromolecular complexes is provided below.
