Which of these statements about the tertiary structure of a polypeptide is(are) untrue? You may select more than one answer. The tertiary structure will be maintained when the solvent is changed from pure water to aqueous acetic acid. O The tertiary structure is determined in part by the formation of disulfide bridges. Hydrogen bonding interactions are responsible for formation of secondary structure but not tertiary structure, O The tertiary structure is rigid and unchanging. O Charge-charge (electrostatic) interactions can be important in the tertiary structure.
Match the structures (i-iv) to the correct molecules from the dropdown list provided. Not all molecules on the list will be used. The list: cholesterol, amino acid, phospholipid, deoxyribose, triglyceride, fatty acid, a steroid hormone i. OH iii. ii. iv. You may also click here to see the image.

Cholesterol has a fused four – ring core and is part of body membranes. The -OH group on C-3 is the polar head, and the rest of the molecule provides the hydrophobic tail that does not fit into the zigzag packing of the hydrocarbon portion of the saturated fatty acids. Considering this structure, tell whether cholesterol contributes to the stiffening (rigidity) or the fluidity of a membrane.
One of the following is not a structural lipid. Sphingomyline Triglycerides Phosphatidylcholine O. All choices are structural lipids Cholesterol
When bonding 1 glycerol molecule, with 3 fatty acid molecules, you can build a tryglceride. In addition to the tryglyceride, can you make any other molecules in the bonding process?
There are some similarities and differences in the structure and function of starch and cellulose. Briefly compare these two substances and describe two major differences and two similarities of these substances.
Lipoproteins transport dietary fats through the bloodstream and deliver them to the cells. Cholesterol (below) is mainly transported as a cholesterol ester via the condensation reaction of cholesterol and a free fatty acid. Draw the structure of the cholesterol ester produced from the condensation of cholesterol and stearic acid (structures here Ł). НО םבי י
What noncovalent interactions (covered in Section 8.2) hold lipid molecules together? Are these forces generally weak or strong? Why do lipids not mix readily with water?
While not a lipid, cholesterol is often found associated with membranes. Explain how a cholesterol molecule is able to be held in place, and which parts of the cholesterol associate with which parts of the lipds. Animals like caribou (a.k.a. reindeer) that live in cold arctic regions such as the north pole often have more cholesterol in their legs than the rest of their bodies. Suggest a reason this may occur (cholesterol does not help with flight).
Phosphoglycerides are composed of: (select all that apply) Group of answer choices sphingosine aminoalcohol phosphate group fatty acids glycerol monosaccharide
Lipoprotein particles are relatively large, sphericalclumps of protein and lipid molecules (see Figure 3.18)that circulate in the blood of mammals. They are likesuitcases that move cholesterol, fatty acid remnants, triglycerides, and phospholipids from one place to anotherin the body. Given what you know about the solubilityof lipids in water, which types of lipids would you predict to be on the outside of a lipoprotein clump, bathedin the water-based fluid portion of blood?
One of the following is not a structural lipid. Sphingomyline All choices are structural lipids Triglycerides Cholesterol Phosphatidylcholine
