Description:
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.<br/><br/>---<br/>? http://www.youtube.com/Best0fScience<br/>? http://www.youtube.com/ScienceMagazine<br/>? http://www.youtube.com/FFreeThinker<br/>---<br/><br/>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.<br/><br/>In the alpha amino acids, the amino and carboxylate groups are attached to the same carbon atom, which is called the ?carbon. The various alpha amino acids differ in which side chain (R group) is attached to their alpha carbon.<br/><br/>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.<br/><br/>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.<br/><br/>Every protein is chemically defined by this primary structure, its unique sequence of amino acid residues, which in turn define the three-dimensional structure of the protein. Just as the letters of the alphabet can be combined to form an almost endless variety of words, amino acids can be linked together in varying sequences to form a vast variety of proteins.<br/><br/>Amino acids are also important in many other biological molecules, such as forming parts of coenzymes, as in S-adenosylmethionine, or as precursors for the biosynthesis of molecules such as heme. Due to this central role in biochemistry, amino acids are very important in nutrition.<br/><br/>Amino acids are commonly used in food technology and industry. For example, monosodium glutamate is a common flavor enhancer that gives foods the taste called umami. They are also used in industry. Applications include the production of biodegradable plastics, drugs and chiral catalysts.<br/><br/>? http://en.wikipedia.org/wiki/Amino_acid<br/><br/>---<br/><br/>The California Academy of Sciences is a world-class scientific and cultural institution based in San Francisco. The Academy recently opened a new facility in Golden Gate Park, a 400,000 square foot structure that houses an aquarium, a planetarium a natural history museum and a 4-story rainforest all under one roof.<br/><br/>The new facility is also home to the Academy's staff of world-class scientists, an education department that provides a wide range of student and teacher services, and an extensive science library with over 26 million specimens and artifacts.<br/><br/>? http://www.calacademy.org/<br/>.
