The Chemicals of Life
This video looks at the basic principles of Chemistry involved in Biology. It explains atoms, molecules, elements and compounds and then looks at the criteria for a compound to be classed as organic. The four major organic compounds in Biology are Carbohydrates, Lipids, Proteins and Nucleic Acids. We call these macromolecules because they are large molecules made up of smaller subunits.
Paul Andersen describes the four major biological molecules found in living things. He begins with a brief discussion of polymerization. Dehydration synthesis is used to connect monomers into polymers and hydrolysis breaks them down again. The major characteristics of nucleic acids are described as well as there directionality from 3' to 5' end. Protein structure is describes as well as the structure of its monomers; amino acids. The carboxyl and amino ends of a protein are described. The major groups of lipids are included with a brief discussion of saturated, unsaturated and trans fats. Finally carbohydrates and their sugar monomers are discussed.
Introduction to Biochemistry
This is a dramatic video choreographed to powerful music which introduces the viewer/student to the amazing Biochemistry of life. It is designed for use by teachers of Biology, Biochemistry and the Life Sciences as an introductory "trailer" showcasing the wonders of life and the amazing chemistry that powers it. As a High School Biology teacher myself, I have found these videos a great way to capture student interest immediately. Please rate this video and feel free to comment. If you like it, please help me spread the word by posting links on your media websites. The more students who can enjoy these dramatic videos, the better! To view all of my videos in Biology, Earth Science, and Astronomy, subscribe to my channel at: http://www.youtube.com/user/sfgregs?feature=mhum. I will be releasing new videos periodically. I wish to thank all the quality video and music producers whose postings enabled me to assemble this video for educational use. To best enjoy this video, turn up your speakers. The music is very powerful and dramatic! I can customize this video to add your name or school name at the end credits, for a very modest fee. If interested, email me at "[email protected]"
