?Molecular biology? is the branch of biology that deals with
molecule-level interactions. Since a molecule is composed of several
atoms, this is most likely the closest sub-discipline (or ?level?) of
biology that is concerned with ?human beings [be] regarded as
converting atoms??. Also closely related would be the discipline of
physiology, more precisely, molecular physiology , since you?re
concerned with atoms in human beings.
