SciShow Takes a Look at Five of the Most Important Molecules in the Human Body

Your body has all sorts of complicated processes going on, and a lot of them are carried out by incredibly powerful molecules.

DNA Molecules Found Between Stars 25,000 Light Years Away In Giant Gas Cloud    "Finding these molecules in an interstellar gas cloud means that important building blocks for DNA and amino acids can 'seed' newly-formed planets with the chemical precursors for life," said Anthony Remijan, of the National Radio Astronomy Observatory (NRAO).

While the variety of candies seems endless, all of them fall into two main categories: crystalline (typically soft and creamy) and non-crystalline (generally hard and brittle). The deciding factor is how the preparation process manipulates the sucrose molecules within sugar. Mmm, crystallization.

The Chemistry Principle That Determines Whether Candy Is Hard Or Soft

There’s over a quarter million times more molecules than cups of water. #mindblown

If you removed the empty space from atoms, the world's human population would fit in the volume of a sugar cube.

Photosynthesis with M&M's.  After learning the photosynthetic equations students put their knowledge to work building the molecules in the equation out of M&M's.  Students are also reminded of the Law Conservations of Mass.  Link to lesson provided.

Biological Molecules – You Are What You Eat: Biology #3

Biological Molecules - You Are What You Eat

Biological Molecules - You Are What You Eat: Crash Course Biology Hank talks about the molecules that make up every living thing - carbohydrates, lipids, and proteins - and how we find them in our environment and in the food that we eat.

In this video Paul Andersen explains how the polarity of water makes life on the planet possible. Oxygen is highly electronegative and pulls the electrons closely creating a partial negative charge. The polarity of water (and the corresponding hydrogen bonds) create cohesion, adhesion, capillary action, high specific heat, and a universally good solvent.
