6. List all four macromolecules and their building blocks (monomers). The four main classes of organic compounds (carbohydrates, lipids, proteins,  and nucleic acids) that are essential to the proper functioning of all living things are  known as polymers or macromolecules.  There are four classes of  macromolecules ( carbohydrates, lipids, proteins, and nucleic acids ).  Carbohydrates  and lipids are made of only carbon, hydrogen, and oxygen (CHO).  Proteins are made of  carbon, hydrogen, oxygen, and nitrogen (CHON).  Nucleic acids such as DNA and RNA  contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P). 1. What three elements do the four macromolecules have in common? Carbohydrates  are used by the body for energy and structural support in cell  walls of plants and exoskeletons of insects and crustaceans.  They are made of smaller  subunits called monosaccharides.  Monosaccharides have carbon, hydrogen, and oxygen  in a 1:2:1 ratio.

"Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
