Chemistry and Synaptic Transmitters - Chemistry and Synaptic Transmitters The most common psychoactive substances can be divided into depressants (i.e., alcohol, sedatives, hypnotics), stimulants (i.e., cocaine, amphetamines, ecstasy), opioids (i.e., morphine and heroine), and hallucinogens (i.e., PCP, LSD, cannabis). The brain has different effects to different psychoactive substances. They bind to different receptor types, and can increase or decrease the activity of neurons through several different mechanisms. Consequently, these psychoactive substances have different behavioral effects, different rates of development of tolerance, different withdrawal symptoms, and different short-term and long-term effects (Vaccarino & Rotzinger, 2004)....   [tags: Chemistry Science Scientific Essays] :: 2 Works Cited :: 5 Sources Cited	1653 words (4.7 pages)	FREE Essays	[view]

Chirality in Chemistry - Chirality in Chemistry Chirality is a term which may be applied to any asymmetric object or molecule. It is the property of non-identity of an object with its mirror image. A chiral compound is one which is not superimposable on its mirror image. This property of molecules has a great importance in the chemistry feild as it provides us with an understanding of the shapes of molecules which then in turn, gives us an insight on the way they react in a particular reaction. Chirality in chemistry is described in many ways but the universal defination of chirality was given by Lord Kelvin in 1904 who defined chirality in his 'Baltimore Lectures' on 'Molecular Dynamics and the Wave Theory of Light' as "I call any geometrical figure, or group of points, chiral, and say it has chirality, if its image in a plane mirror, ideally realized, cannot be brought to coincide with itself."

Chemistry of Psilocybin and Synaptic Transmitters Involved - Chemistry of Psilocybin and Synaptic Transmitters Involved Psilocybin is a type of hallucinogenic mushroom that is ingested by eating the raw fungi. The mushroom can also be made into a tea and drunk. In some of the later studies done on psilocybin, the drug was synthetically produced and then either inhaled or injected by an IV. The drug enters the blood stream and can cross the blood brain barrier because of it relative metabolic similarity to serotonin (Fuller 1985). This means that since psilocybin is chemical resemblance to the neurotransmitter serotonin, psilocybin can trick the protein channels embedded in the membrane of the blood vessel and pass through as if it were serotonin and not a drug....   [tags: Chemical Drugs Drug papers] :: 12 Works Cited	1779 words (5.1 pages)	FREE Essays	[view]

chemistry (ocean) - What is an iceberg. Why are they blue or green. An iceberg is a large floating block of freshwater ice that has broken off the edge of a glacier and been carried out to sea; about 90% of its mass lies under the water. The bluish streaks of clear, bubble free ice often seen in icebergs results from the refreezing of melt water which fills crevasses formed in the glacier as it creeps over land. The ice is blue because of the natural light scattering characteristics of pure ice. Occasionally airborne dust or dirt eroded from land ends up on the glacier surface eventually forming a noticeably darkened brown or black layer (in any orientation) within the ice of a floating iceberg....   [tags: essays research papers]	872 words (2.5 pages)	FREE Essays	[view]
Physics chemistry - ATHENS, Ohio -- Today's computers and other technological gizmos operate on electronic charges, but researchers predict that a new generation of smaller, faster, more efficient devices could be developed based on another scientific concept -- electronic "spin." The problem, however, is that researchers have found it challenging to control or predict spin – which keeps practical applications out of reach. But physicists in Europe, California and at Ohio University now have found a way to manipulate the spin of an electron with a jolt of voltage from a battery, according to research findings published in the recent issue of the journal Physical Review Letters....   [tags: essays research papers]	517 words (1.5 pages)	FREE Essays	[view]

Separation of M-toluic Acid, Acetanilide, and NaCl - Discussion Overall this experiment was a success yielding 98.8% of the initial 1.34g of known compounds. Looking at Table 1 the problem of separation quickly becomes apparent, both M-Toluic Acid and Acetanilide are insoluble in water. This left two non-salts in one mixture, and what solvent to use to separate these two was the most important question as their respective melting points are also very similar. After looking at both compounds and noticing the M-Toluic Acid (Image 2) had an OH group hanging off of it next to a double bond, the H ion on the end would be susceptible to a base....   [tags: Chemistry]	505 words (1.4 pages)	Unrated Essays	[preview]
