An amino acid structure contains a -COOH and -NH2 group in the same molecule. The -COOH group donates a proton to the -NH2 group. Because of this, the amino acid structure contains a positive charge on one atom and a negative charge on the other. What is the term used to refer to this character of amino acids? O Amphiphatic O Isoelectric point Zwitterions O Amphoteric

The figure below illustrates the molecular structures of two fatty acids. 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.
