2013, la Olimpiada Peruana de Química (OPQ) se hace adulta
(Pontificia Universidad Católica del Perú, 2013-03-26) Comité Permanente de la OPQ, Comité Permanente de la OPQ
The Peruvian Chemistry Olympiad celebrates its 18th birthday with good results in the international competitions in Russia (45th International Chemistry Olympiad, IChO), where two of our students were awarded with bronze medals, and in Bolivia (18th Olimpiada Iberoamericana de Química, OIAQ), where each one of them managed to reach a bronze medal.

Moléculas y formulaciones con nombres extraños o antiguos
(Pontificia Universidad Católica del Perú, 2013-03-26) Plée, Dominique
Through history, the names of many molecules have changed. It is interesting to remember those forgotten names and to try to track their origin. There are also molecules that are not so well known and which have peculiar names which are able to induce smiles or astonishment to English speaking people (especially those who understand the slang). Nevertheless, it’s not necessary to be a Shakespeare’s fan to understand and appreciate this funny nomenclature.

El amor: hay (bio)química entre nosotros
(Pontificia Universidad Católica del Perú, 2013-05-19) Manrique Muñante, Rubén
Romantic love involves biochemical processes in which substances such as neurotransmitters, neuromodulators and hormones interact with other nerve cells or organs. When being in love, dopamine levels increases, generating attention, desire and motivation in everything related to the beloved person. Serotonin, however, is present in low levels in this state. When the body does not supply the necessary amount of dopamine, oxytocin is released. Oxytocin is vital in long term relationships. Understanding the mechanism of oxytocin in humans is crucial not only for academic knowledge of the chemistry of love but also because it provides new lights for the treatment of some psychological disorders.

Un laboratorio de silicio: química sin reactivos
(Pontificia Universidad Católica del Perú, 2013-05-19) Benites Galbiati, Martín
The 2013 Nobel Prize in chemistry was awarded to A.Warshel, M.Levitt and M.Karplus for their contribution to the development of hybrid methods for computational chemistry. In this article a brief introduction about computational chemistry methods is presented. This paper will show the order in which the QM/MM (Quantum Mechanics/Molecular Mechanics) methods were developed for the study of macromolecular systems and specially their application in enzymes and biochemistry. Finally, the reach and future prospects of these methods originally developed by A. Warshel, M.Levitt and M. Karplus in the seventies will be discussed.

Cervezas Amargas: un problema de orientación espacial resuelto
(Pontificia Universidad Católica del Perú, 2013-05-19) Medina, Juan Pablo
Determination of the stereochemistry of organic compounds has been a problem that the scientific community has been giving solution to over the years. Different methods have emerged, such as X-ray Diffraction or different types of Nuclear Magnetic Resonance (NMR). However, it just has been discovered that the method used in the determination of the absolute configuration of the α-acids derived from hops used in the manufacture of bitter beers, was not the appropriate.

Química inspirada en la naturaleza: diseño de seudopéptidos macrocíclicos
(Pontificia Universidad Católica del Perú, 2013-12-06) Martí-Centelles, Vicente; Burguete, M. Isabel; Luis, Santiago V.
The molecular design based on the imitation of the complex structures and processes found in nature is known as bioinspired Chemistry or biomimetic Chemistry. An approach used in this discipline is the preparation of macrocyclic pseudopeptidic compounds from natural amino acids and abiotic components. Proteins exist in nature with very specific properties encoded by the diverse structural and conformational information of the amino acids side chains. The use of this information is a key factor in the design of pseudopeptides with well-defined properties. Therefore, a suitable structural design to obtain the desired functionality relies on the appropriate choice of structural components, natural and abiotic.

El mundo del arte y la arqueología: ¿El lugar ideal para un químico?
(Pontificia Universidad Católica del Perú, 2013-12-06) Gonzales Gil, Patricia
Although we may think that studies of archaeological and artistic objects are mainly historical or stylistic, a chemical approach can also provide important information about them. In a country like ours, with a vast cultural heritage, a chemist can do a lot to further our knowledge of these objects and to help in their conservation.
