Science & Reason on Facebook: tinyurl.com Does life exist elsewhere in the Universe? Perhaps. In August 2009, scientists announced the discovery of the amino acid, glycine, on the comet Wild 2. Amino acids provide key components for life here on Earth, but this is the first time we have definitive evidence of these molecules occurring in space. --- Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com • www.youtube.com --- Amino acids are molecules containing an amine group, a carboxylic acid group and a side chain that varies between different amino acids. These molecules are particularly important in biochemistry, where this term refers to alpha-amino acids with the general formula H2NCHRCOOH, where R is an organic substituent. In the alpha amino acids, the amino and carboxylate groups are attached to the same carbon atom, which is called the αcarbon. The various alpha amino acids differ in which side chain (R group) is attached to their alpha carbon. These side chains can vary in size from just a hydrogen atom in glycine, to a methyl group in alanine, through to a large heterocyclic group in tryptophan. Amino acids are critical to life, and their most important function is their variety of roles in metabolism. One particularly important function is as the building blocks of proteins, which are linear chains of amino acids. Every protein is chemically defined by this primary structure, its unique sequence of amino acid residues ...
The Standard model is what I call the Periodic Table of fundamental Particles...There are three generations of differeing energies and we are in the third or first however you want to look at it but it's the lowest energy up, down Quarks and the electron/anti-neutrino pair. Protons are the simplest hydrogen with NO neutrons and make neutrons in stars and release ANTI-Electrons (anti-matter! YES in the core of the sun to make a more massive neutron in this case a deuteron a proton adn a neutron otherwise the neutron would decay without being bound to a proton and two protons won't fuse so the neutrons are the key!!!! proton one up 2 down QUARKS.Alpha particles are the next building block with two protons and two neutrons you'll see three are carbon-12 and another makes the oxygen-16 and another makes the neon-20
