If a molecule is a phytochemical, its source is a plant; If a molecule is an antioxidant, its function is to inhibit the creation of free radicals by biological reactions; Many, but not all, phytochemicals are antioxidants; Many, but not all, antioxidants are phytochemicals; The biological function is a far more important characteristic than is the biological source.
We have all been told to eat fruits and vegetables because they contain antioxidants, flavonoids, and other phytochemicals. What are the molecular identities, molecular structures, and organic-chemical classes for these molecules? EBooks 16 (antioxidants) and 17 (phytochemicals) answer this question.
This eBook presents molecular models for sixty-one (61), different antioxidant molecules. For 38 of these molecules, three types of model are provided:
(1) A two-dimensional (2D), skeletal model.
(2) A ball-and-stick model
(3) A three-dimensional (3D), space-fill model
This eBook can provide a transition from the skeletal-model approach (which is typical of most introductory-chemistry textbooks) to the three-dimensional -model approach (which is typical of several eBooks in the Enrichment Chemistry™ Series).
The Enrichment Chemistry Series™ version 2.0 will soon consist of nineteen eBooks that present an alternative approach to the teaching of chemistry at any educational level. The focus of this alternative approach is molecules – “the smallest units of meaning in chemistry” -- which author Philip Ball stated in his book, Stories of the Invisible. Our point of view leads to a logical sequence of chemistry topics such as molecular identity molecular location molecular amount molecular rate process molecular scale molecular chemical engineering.
The Molecular Identity eBook will soon expand to include several groups of molecules such as (1) Molecular Aromas and Fragrances, (2) Molecular Nutrition, (3) the Molecular Environment, (4) Antioxidants, (5) Phytochemicals, (6) Nutraceuticals, and (7) either Antibiotics or Pharmaceuticals. In conclusion, we all live in a world of molecules, so we might as well learn what they are, where they are located, and what they do.
