Chemistry of the Human Body

Most anatomy courses list basic chemisry as a prerequisite. This is fundamentally important for anatomy students, as all the processes of human metabolism are based in the principles of chemistry. Without a solid understanding of the basics of atoms, molecules, and chemical reactions, some of the body systems are near-impossible to fully comprehend. The purpose of this chapter is to refresh students on atomic structure, chemical reactions, and other relevant topics from chemistry they will need to be successful in this course..


Human Chemistry and Macromolecules Lecture Powerpoint

View Lecture
Chemistry of the Human Body Lecture Powerpoint

Purpose: This Powerpoint covers the most important chemistry concepts needed to be successful in the human anatomy and physiology course. A strong emphasis is placed on covalent bonding within organic compounds, as these examples will be the most relevant. The four major classes of macromolecules: carbohydrates, lipids, proteins, and nucleic acids are also introduced at this point.

Essential Concepts: Atomic structure, protons, neutrons, electrons, ions, isotopes, covalent bonds, ionic bonds, hydrogen bonds, water, cohesion, adhestion, pH, acid, base, organic chemistry, water properties, atoms, chemical reactions, elements, compounds, nucleus, atomic number, atomic mass, electron cloud, carbon dating, polarity, polar, nonpolar, pH scale, van der waals, molecular shape.

Human Chemistry Student Notes Outline

Purpose: Taking efficient notes can be a big challenge for many students, especially when working from a Powerpoint lecture. This outline gives students a means to take notes that guides them toward important concepts and avoids the pitfalls of writing word-for-word or simply not taking notes at all. The outline lays out each of the key concepts, ideas, and blank diagrams that students are expected to learn. They fill in the missing details as the lecture proceeds.

Essential Concepts: Atomic structure, protons, neutrons, electrons, ions, isotopes, covalent bonds, ionic bonds, hydrogen bonds, water, cohesion, adhestion, pH, acid, base, organic chemistry, water properties, atoms, chemical reactions, elements, compounds, nucleus, atomic number, atomic mass, electron cloud, carbon dating, polarity, polar, nonpolar, pH scale, van der waals, molecular shape, macromolecules, carbohydrates, lipids, proteins.


Molecular Models of Covalent Compounds

Purpose: The electron sharing that occurs within covalent compounds can be a very abstract concept to understand. Many chemistry (and biology) classes will provide students with model kids to make covalent bonding a little more concrete. This worksheet is meant to accompany a class working with these models to build specific organic compounds.

Essential Concepts: Covalent compounds, covalent bonding, electron sharing, organic compounds, electron shell diagram, structural notation.


The Effect of Temperature on the Catalase Enzyme Lab

Purpose: Catalase is one of the most popular enzymes to use with introductory-level biology and anatomy students, because it is easy to get, and the chemical reaction it catalyzes is very visible. This is a set of instructions for students to design a series of procedures to test the level of activity of the enzyme under different temperature conditions. This enzyme is also not specific to any body system, so no prior anatomy knowledge is really necessary.

Essential Concepts: Enzymes, catayze, decomposition reaction, denaturation, effects of temperature on enzymes.


Chemical Tests for Carbohydrates, Lipids, Proteins, and Nucleic Acids Lab

Purpose: This is an instructional lab that leads students through the procedures of identifying carbohydrates, lipids, proteins, and nucleic acids with a set of chemical tests. The tests used include Benedict's reagent, iodine, Biuret, and dische diphenylamine. Students will conduct these tests on distilled water as a control, then compare with a series of standard substances, like vegetable oil and starch.

Essential Concepts: Macromolecules, monosaccharides, starch, proteins, amino acids, lipids, Benedict's solution, Biuret, iodine, dische diphenylamine.

Purpose: This worksheet is a set of vocabulary words and practice questions meant to encourage students to condense their notes into a more manageable form to study from. The questions and vocabulary are taken directly from the lecture Powerpoint for this unit.

Essential Concepts: Atomic structure, protons, neutrons, electrons, ions, isotopes, covalent bonds, ionic bonds, hydrogen bonds, water, cohesion, adhestion, pH, acid, base, organic chemistry, water properties, atoms, chemical reactions, elements, compounds, nucleus, atomic number, atomic mass, electron cloud, carbon dating, polarity, polar, nonpolar, pH scale, van der waals, molecular shape.
