5 True/False questions
Tertiary → the actual sequence of the amino acids
Macromolecules → m. wt. 10^3- 10^9; nucleic acids, proteins, lipids, polysaccharides. 4 most important to study.
Conjugated Proteins → contains only amino acids
Protein Properties → Made up of repeating units of amino acids (about 20 types); Subunits linked by peptide bonds forming polymers; Function: structural support, antibodies, contractile fibers, toxins, transport.
Primary → The overall 3D structure of the polypeptide chain. Held together by different bonds: peptide, ionic, hydrogen, covalent, sulfhydryl, etc. Prions are proteins that don't take their correct 3D shape and are harmful; mad cow disease.
