Scientists Discover New Clue to Chemical Origins of Life ScienceDaily (Jan. 24, 2012) — Organic chemists at the University of York have made a significant advance towards establishing the origin of the carbohydrates (sugars) that form the building blocks of life. A team led by Dr Paul Clarke in the Department of Chemistry at York has re-created a process which could have occurred in the prebiotic world. Working with colleagues at the University of Nottingham, they have made the first step towards showing how simple sugars — threose and erythrose — developed. The research is published in Organic & Biomolecular Chemistry. All biological molecules have an ability to exist as left-handed forms or right-handed forms. All sugars in biology are made up of the right-handed form of molecules and yet all the amino acids that make up the peptides and proteins are made up of the left-handed form. Read More
