The best description of a glycoprotein is only amino acids polymerized in a chain amino acid chains with covalently bound heme groups amino acid chains and bound carbohydrate O a protein with a covalently bound lipid a polysaccharide with a fatty acid modification

Which of the following is the primary driving force for protein folding? disulfide bridges internal hydrogen-bonds the hydrophobic effect Van der Waals forces O salt bridges

Provide the smallest molecular unit of most lipids, proteins, and nucleic acids. Keep in mind that lipids are a little tricky.

The following is an example of which level of protein structure? What bonds form this level of structure? Asp-Met-Leu-Trp-Gly-Asn-Lys

x * x A () lipids: fatty acids and glycerol proteins: amino acids carbohydrates: disaccharides H HỎ D carbohydrates: monosaccharides E nucleic acids: nucleotides CH₂OH H OH H Carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form other biomolecules. The picture above shows sucrose, a disaccharide used to form larger biomolecules. Biomolecules are all made of smaller units called monomers. Examine the list of biomolecules below. Select ALL of the choices that correctly pair the biomolecule with its monomer. QH H H OH Y CH₂OH 0 Q CH₂OH H HO OH H H 5 of 10 32

Select the properties that apply to the secondary structure beta-pleated sheets (select all that apply). can be Antiparallel can be Parallel are right handed Oare left handed obeys n+4 rule are formed by the pattern of hydrogen bonding the backbone makes with itself are formed by the pattern of covalent bonds the backbone makes with itself are formed by the pattern of electrostatic attractions the backbone makes with itself

Which of the following statements is TRUE? O Urea disrupts primary protein structure Trace amounts of BME fully reduce oxidized proteins Oxygen reduces oxidized proteins None of these options is true
