The chemical name N5-ethyl- L -glutamine  and other synonyms see box for theanine reflect its chemical structure. The name theanine, without prefix, is generally understood to imply the L - S- enantiomerderived from the related proteinogenic L-amino acid glutamic acid. Theanine is an analog of this amino acid, and its primary amideL - glutamine also a proteinogenic amino acid. Relative to theanine, the opposite D - R- enantiomer is largely absent from the literature,  except implicitly.
Neurophysiology Virtual Lab pilot Neurophysiology is the study of nervous system function. Primarily, it is connected with neurobiology, psychology, neurology, clinical neurophysiology, electrophysiology, biophysical neurophysiology, ethology, neuroanatomy, cognitive science and other brain sciences.
Neuron Simulation Virtual Lab pilot This lab uses a graphical web-based Neuron simulator and models a section of excitable neuronal membrane using the Hodgkin-Huxley equations. Various experiments will deal with the several parameters of Hodgkin-Huxley equations and will model resting and action potentials, voltage and current clamp, pharmacological effects of drugs that block specific channels etc.
This lab complements some of the exercises in the Virtual Neurophysiology lab. Biochemistry Virtual Lab I Biochemistry is the study of the chemical processes in living organisms. It deals with the structures and functions of cellular components such as proteins, carbohydrates, lipids, nucleic acids and other biomolecules.
The experiments included in Biochemistry Virtual Lab I are fundamental in nature, dealing with the identification and classification of various carbohydrates, acid-base titrations of amino acids, isolation of proteins from their natural sources, etc.
Biochemistry Virtual Lab II Biochemistry Virtual Lab II deals with topics like enzymology, purification of plant pigments and natural products as well as estimation of iodine value and saponification value of fats and oils. Population ecology Virtual Lab I A population is a collection of individuals of the same species that live together in a region.
Population ecology is the study of populations especially population abundance and how they change over time. Crucial to this study are the various interactions between a population and its resources.
Studies on simple models of interacting species is the main focus this simulation oriented lab.
Population ecology Virtual Lab II Population ecology is the study of populations especially population abundance and how they change over time. Studies based on models of predation, competition as seen in interacting species is the main focus this simulation oriented lab. Lab II focuses on applied principles of population ecology for PG students.
Immunology Virtual Lab I The branch of biomedicine concerned with the structure and function of the immune system, innate and acquired immunity, the bodily distinction of self from no self, and laboratory techniques involving the interaction of antigens with specific antibodies.
Immunology Virtual Lab II The branch of biomedicine concerned with the structure and function of the immune system, innate and acquired immunity, the bodily distinction of self from no self, and laboratory techniques involving the interaction of antigens with specific antibodies. Microbiology Virtual Lab I The study of microorganisms, which are unicellular or cell-cluster microscopic organisms.
Abstract: Caffeine was extracted from tea by the use of solid-liquid and liquid-liquid extractions. An acid/base liquid-liquid extraction took place in order to force caffeine into the organic layer. A pure product of g caffeine was obtained. If you want to know which hamstring exercises and workouts build the best legs, then you want to read this article.

This includes eukaryotes such as fungi and, protists and prokaryotes. Viruses, though not strictly classed as living organisms, are also studied.
Microbiology Virtual Lab II To study the biochemical properties of microorganisms, the various techniques employed in cultivation of fungi and viruses along with the molecular level analysis of microbial genome.
This field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.
Cell biology Virtual Lab I Cell biology is an exciting and dynamic area that helps discover the fascinating world of cells.
It includes the study of the structure and organization, growth, regulation, movements and interaction of the cells. Cell biology is closely related to other areas of biology such as genetics, molecular biology, and biochemistry.

Structure, properties, spectra, suppliers and links for: Caffeine, 4) A possible explanation for a lower than expected melting point observed for caffeine that is less than °C could be due to impurities within the caffeine sample. Elizabeth Ping | November 22, | 3 References: "Isolation of Caffeine from Tea".
2. Composition and role of each material in extraction Tea-Leaves of Camellia Senesisv which are used to brew a popular beverage. The leaves contain cellulose, chlorophyll, flavonoids, tannins and caffeine.
Fortunately, Caffeine is soluble in polar aprotic solvents whereas the Tannins are soluble in protic solvents due to hydrogen bonding. Thus, we can carry-out the isolation of caffeine from tea leaves in the following steps: 1.
Extract the Caffeine and Tannins into hot Water. 2. Extract the Caffeine into a non-polar organic solvent; Methylene Chloride.
