What is a saturated fatty acid?
A. carbon atoms are bonded to as many hydrogen atoms as possible. This causes the molecules to form straight chains
B. some carbon atoms are not bonded to as many hydrogen atoms as possible. Instead, they are bonded to other groups of atoms. Wherever carbon binds with these other groups of atoms, it causes chains to bend
