To review:
The importance of polar and nonpolar groups in the structures of lipids, proteins, and
Introduction:
Lipids are insoluble in water and mostly nonpolar in nature. These are of three basic types, namely: neutral lipids, phospholipids, and steroids. Nucleic acids are biomolecules formed by

- Explain the significance φ, ψ contour diagram in proteins and explore how is it interpretedarrow_forwardProtein Structure and Folding:a. Explain how changes in a protein’s amino acid sequence can change the way it behaves in water.b. Explain how changes in a protein’s amino acid sequence can change the way it interacts with othermolecules.c. Explain how changes in a protein’s amino acid sequence can change the way it forms secondary andtertiary structures when placed in water.arrow_forwardDiscuss major functions of lipids in cells.arrow_forward
