The Ecstatic is the fourth album by American rapper Mos Def (pictured) , released by Downtown Records on June 9, 2009. Singer Georgia Anne Muldrow and rappers Slick Rick and Talib Kweli were guest vocalists. The album has been described by music journalists as a conscious and alternative hip hop record. Mos Def's raps about global politics, love, spirituality, and social conditions are informed by Black internationalism and pan-Islamic ideas. The album's loosely structured, lightly reverbed songs use unconventional time signatures and samples taken from Afrobeat , soul , Eurodance , jazz , reggae , Latin , and Middle Eastern music . The Ecstatic charted at number nine on the Billboard 200 in its first week of release and eventually sold 168,000 copies. A widespread critical success, The Ecstatic was viewed as a return to form for Mos Def and one of the year's best albums. He performed concerts to support the record in North America, Japan, Australia, and the United Kingdom. (Full article... )

In biochemistry , this term refers to alpha-amino acids with the general formula H2 NCHRCOOH, where R is an organic substituent.[1] In the alpha amino acids, the amino and carboxylate groups are attached to the same carbon , which is called the α–carbon . The various alpha amino acids differ in which side chain (R group) is attached to their alpha carbon. They can vary in size from just a hydrogen atom in glycine through a methyl group in alanine to a large heterocyclic group in tryptophan .
Beyond the amino acids that are found in all forms of life , many non-natural amino acids have vital roles in technology and industry. For example, the chelating agents EDTA and nitrilotriacetic acid are alpha amino acids that are important in the chemical industry . (more... )
