same side of the C-C single bond. Concerning the stereochemistry of the product‚ the Diels-Alder reaction is stereo selective‚ usually yielding only one of several possible stereoisomer. The addition of maleic anhydride to a diene yields entirely the endo product in which the bulkier parts of the dienophile are closer to the carbon-carbon double bond.Dienes and trienes occur in the essential oils of a number of plants and contribute to the flavors and aromas of certain plants. Most conjugated dienes

Rohith Bhatia THST 175 8 December 2011 Theology Final Paper Throughout my experiences in Narratives of Christian Faith‚ many themes have come across. However‚ the three I feel are most prominent are resisting temptation‚ the silence of God‚ and the discernment of spirits. These themes can be seen in the works of Antony‚ Ignatius‚ Silence‚ and Medieval Writings on Female Spirituality. Resisting temptation can be seen in The Life of Antony. Antony realized that there is more to life than

Endometriosis Endometriosis is a complicated‚ debilitating disease that is poorly understood and all too frequently misdiagnosed. Most patients have experienced excruciating pain for years. More than 5.5 million women in North America‚ and 176 million women worldwide suffer from endometriosis. Many of these women receive inadequate treatment. Endometriosis is a condition where the cells that line the uterus grows outside the uterus in other areas. Endometriosis is considered to be a common gynecological

each one has a double layered membrane which is similar to the cell membrane but has several folds which produces a series of “shelves” which are called cristae. Endoplasmic reticulum(ER): There are two types of ER which are called rough and smooth. Endo translates to “within” and reticulum is a term for network‚ therefore ER is a branching network inside

c------------------------------------------------- Evidence for Endosymbiotic theory: ------------------------------------------------- Evidence that mitochondria and plastids arose from bacteria is as follows:[13][14][15] * New mitochondria and plastids are formed only through a process similar to binary fission. * In some algae‚ such as Euglena‚ the plastids can be destroyed by certain chemicals or prolonged absence of light without otherwise affecting the cell. In such a case‚ the

Release of calcium—sarcoplasmic reticulum release channels‚ RyR1 and IP3 receptors (Rossi & Dirksen‚ 2006). At this step‚ ions of calcium are released into the sarcoplasm making the muscle contract (Martini & Nath‚ p. 298). Calcium recycling—Sarco(endo)plasmic reticulum calcium2+ and -ATPase or SERCA pumps (Rossi & Dirksen‚ 2006). This step is done via the terminal cisternae in the SR. Skeletal muscle fibers pump calcium ions out of their cells via transport through the plasma membranes as many

the side with more gas molecules. If the temp. increase‚ the equilibrium will shift away from the heat. The opposite would happen when the temp. decrease. Decrease temp. will shift toward the heat. (Heat is determined by whether the equation is an endo or exothermic. Endothermic consume heat‚ exo. generates heat. Equilibrium constants can be obtained from the ratio written from equilibrium expressions. The ratio of product over reactant will give K (known as the constant). If k is greater than 1

These differences are perhaps most highlighted in the medical field where stereochemistry of a molecule can be the difference between having a medically active‚ effective drug and a toxic‚ potentially
