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.

"Potassium Bromate (KBr03) is added to flour as a softener that strengthens the texture of bread. It can do this by forming disulfide bonds between two cysteine amino acids in a reaction similar to the chemical equation given below. The function of KBr03 is to remove the 2 electrons needed to form the disulfide bond as shown in the figure below. Each of the cysteine amino acids will be in a protein chain, so the reaction binds the two chains together, giving the dough cohesion. However, potassium bromate is a proven carcinogen and is only allowed in foods in the United States because bakers will add the right amount and correct It has been assumed to meet the temperature and cooking time conditions.

A B H₂C The structural formula of erucic acid and behenic acid с H₂C D erucic acid behenic acid Which of the following best explains why erucic acid is liquid at room temperature but behenic acid is solid at room temperature? O OH The presence of a double carbon to carbon bond in erucic acid prevents the molecule from packing closely together. The lack of any double carbon-carbon bonds in behenic acid causes the molecule to be come polar and therefore packed more tightly. The larger number of carbon atoms in erucic acid prevents the molecule from packing tightly together. OH The smaller number of carbon atoms in behenic acid creates stronger covalent bonds between the carbon atoms allowing for them to pack more tightly together.
