Explain how the terms atom, compounds, element, and molecules all relate to one another

For starters, atoms are the basic building blocks of matter- they make up elements, molecules and compounds. Elements most often combine with other elements as compounds. Whilst molecules are particles found in both elements and compounds. I hope that wasn't too confusing, but bottom line is that they are all linked together in this way! Helpful? :)

Molecules called lipids have long hydrocarbon chains that determine the way they act. they can be fats, oils, or hormones, and even exist in our cell membranes
