What causes a molecule to have a bent shape instead of a linear shape?

Answer 1

Sometimes proteins are folded, or bent as you say, in very complex shapes. There are several reasons for this. The shape is important in how the protein works. Ones that are misfolded don't work. There are even ones that cause disease because they are misfolded. Sometimes they have to be 'packaged' so that they will fit where they need to go. Our DNA molecule is vey long but it needs to fit into the cell nucleus. There are attractions between the atoms in the molecules that cause this folding.
