The Miracle of Life: Carbohydrates, Proteins, Lipids & Nucleic Acids video can be viewed at (3:28). In a dehydration reaction, water is removed as two monomers are joined together. This one is about carbon, one of the most important elements. Chemical reactions are interpreted as word equations, and timelines chart the history. The team at periodicvideos has created a TED-Ed Lesson for every element of the periodic table. Helps cells keep their shape, makes up muscles, speeds up chemical reactions, carries messages and materialsĬarbon, hydrogen, oxygen, nitrogen, phosphorusĬontains instructions for proteins, passes instructions from parents to offspring, helps make proteinsĬarbohydrates, proteins, and nucleic acids are large molecules (macromolecules) built from smaller molecules (monomers) through dehydration reactions. Information boxes and tables contain listings of facts and figures. Stores energy, forms cell membranes, carries messagesĬarbon, hydrogen, oxygen, nitrogen, sulfur ![]() Located between boron (B) and nitrogen (N), it is a very stable element. Provides energy to cells, stores energy, forms body structures Carbon is the sixth element in the periodic table. Carbon-14 is the isotope used for carbon dating, which might one day prove useful in establishing the age of some of these. You can compare the four types in Table below. Fact boxGroup14Sublimes at 3825C, 6917F, 4098 KBlockp3.513 (diamond) 2.2 (graphite)Atomic number612. In fact, there are nearly 10 million carbon-based compounds in living things! However, the millions of organic compounds can be grouped into just four major types: carbohydrates, lipids, proteins, and nucleic acids. ![]() This property allows carbon to form a huge variety of very large and complex molecules. Why is carbon so basic to life? The reason is carbon’s ability to form stable bonds with many elements, including itself.
