Protein Molecular Structure Illustration

An intricate molecular illustration presenting a protein as a ribbon diagram. It clearly displays the characteristic secondary structures: alpha-helices shown in orange, beta-sheets in blue arrows, and connecting loops in purple. Subtle features such as a bound atom or ion, represented by a small brown sphere, and a ring-like molecule, indicated by green and red dots, are also visible within its complex biological architecture.
