Which noncovalent interactions (discussed in Section 8.2) are responsible for the cohesion of lipid molecules? Is the overall strength of these forces weak or strong? Why are lipids incompatible with water?

Amylopectin is a highly branched monosaccharide linkage that tends to break down more rapidly.     True    False

Amino acids differ because they are very “R” groups. Is this a result of amino acids ability to form peptide bonds? True or false

True / False: β-bends can link together α-helices and β-sheets.
