Fluidity of membrane: liquid crystal. Fluidity controlled by cholesterol, tail packing. Proteins account for more than 50% of the dry mass of most cells. Protein functions include structural support, storage, transport, cellular communications, movement, and defense against foreign substances. Proteins. The Role of Enzymes. Success criteria. By the end of this lesson we will be able to:. State what elements are found in proteins. Describe what is meant by primary, secondary and tertiary structure of proteins.. What to Know. What are some protein functions?. General principles for protein folding. General structural features of globular and structural proteins. Know the 4 common globular protein motifs. Understand how protein structures are stabilized and why some portions of proteins are marginally stable. Part II: Proteins & Nucleic Acids. The FOUR Classes of Large Biomolecules. All living things are made up of four classes of large biological molecules: . Carbohydrates . Lipids. Protein. N. ucleic Acids. Cytoplasm.  . Cytoplasm . material between plasma membrane& nucleus. site of most cellular activity. 3 elements. Cytosol. Organelles. Inclusions . Cytosol. . viscous, semitransparent fluid in which other elements in cytoplasm are suspended. Components of DNA. Sugar = Deoxyribose. Ribose is missing hydroxyl group (-. OH. ) from 2’C. Phosphate = PO. 4. 3-. Links to the sugar @ either its 3’C or its 5’C. Water (H. OH. ) is lost in the condensation reaction.
