Municipal Solid Waste Pollution Prevention
1,019 wordsThe Presidential Green Chemistry Awards-Dr. Mark Holtzapple In 1996, Mark Holtzapple of Texas A&M University received the Academic Award for the Green Chemistry challenge. This award was given to him for the development of a family of technologies that converts waste biomass into animal feed and industrial chemicals and fuels by adding lime to a fermentation process. This waste biomass includes municipal solid waste, sewage sludge, manure, and agricultural residues. As we all know all of these w...

Amino Acids Stress Hormones
1,374 wordsIn 1975, Dr. John Hughes and Dr. Kosterlitz discovered Endorphins. It has been confirmed that Endorphins have both neurological and spinal effects. Twenty different types of Endorphins have been discovered in the nervous system. The most effective, beta-endorphin, which gives the most euphoric effect to the brain, has been found to be composed of 31 amino acids. The word Endorphin is abbreviated from 'endogenous morphine' which means morphine produced naturally in the body. Endorphins are renown...

Nitrogenous Bases Amino Acids
999 wordsDeoxyribonucleic acid and ribonucleic acid are two chemical substances involved in transmitting genetic information from parent to offspring. It was known early into the 20 th century that chromosomes, the genetic material of cells, contained DNA. In 1944, Oswald T. Avery, Colin M. MacLeod, and Maclyn McCarty concluded that DNA was the basic genetic component of chromosomes. Later, RNA would be proven to regulate protein synthesis. DNA is the genetic material found in most viruses and in all cel...

Acetic Acid H 3
842 wordsIn the simple formalism proposed independently by Bronsted and Lowry in 1923, an acid was defined as a proton donor and a base was defined as a proton acceptor. In the simple acid-base reaction shown below, H 3 O+ is termed a Bronsted Acid, and HO- a Bronsted Base. In writing organic reaction mechanisms, the flow of electrons is often shown using "curved arrows" and in the example shown, the arrows are designed to show that an unshared pair of electrons from hydroxide anion moves to abstract a p...

Sodium Hydroxide Universal Indicator
854 wordsExperiments to Determine the Effect of Acids & Bases on Different Indicators and the pH of Common Cleaning Agents The aim of the first set of experiments is to find out and record the colour changes that are observed after a certain indicator is mixed with acids and bases to form a colour reaction. Once the selected indicator has been mixed with a acid that is both weak and strong and a base / alkali that is both weak and strong we are to record the colour and choose another indicator. The purpo...

Amino Acids Dna Molecule
1,152 wordsIntroduction Deoxyribonucleic acid is contained in all cells. The structure of DNA makes gene transmission possible. Since genes are segments of DNA, DNA must be able to make exact copies of itself to enable the next generation of cells to receive the same genes. The DNA molecule looks like a twisted ladder. Each "side" is a chain of alternating phosphate and deoxyribose sugar molecules. The "steps" are formed by bonded pairs of purine-pyrimidine bases. DNA contains four such bases the purines a...

Digestive Juices Digestive Tract
1,493 wordsDigestive System, series of organs put together that purpose is to break down, or digest, the food we eat. Food is made up of large things called, complex molecules, which the digestive system breaks down into smaller things called simple molecules that get absorbed into the bloodstream. The bloodstream is our blood. The simple molecules travel through the bloodstream to all of the parts of the body, which we use for growth, repair, and energy. All living things that eat to get energy have a dig...

Fatty Acids Nerve Fibers
496 wordsThe full name of ALD is Adrenoleukodystrophy. It is a rare X chromosome sex linked metabolic disorder that is characterized by the loss of myelin on nerve fibers within the brain. Myelin is the fatty covering on the nerve fibers. The disease causes the continued degeneration of the adrenal gland. The basic defect is that the impaired capacity to degrade very long chain fatty acids that are found in the blood plasma and tissues of the body. These fatty acids accumulate in the cerebral white matte...

Amino Acids Peptide Bonds
367 wordsA gastric gland is a tubular structure in the vertebrate stomach that secretes gastric juices. The gastric glands have three types of cells that secrete different components of the gastric juice. One of them is being a chief cell, which is a rust color and is an inactive form of the digestive enzyme Pepsin. Pepsin begins the digestion of proteins in food. Pepsin is a Peptidases, which is an enzyme that breaks peptide bonds of proteins. Pepsin is found in the mucosal lining of the stomach that br...

Paranoid Schizophrenia Amino Acids
1,720 wordsApril, 1956: The pharmaceutical company Parke & Davis first synthesize what they believe to be the perfect anesthetic (Souza, 1995). When administered to patients, it causes a completely dissociative state, with no significant respiratory or cardiovascular depression. Patients appear to be awake, eyes open, breathing normally. but are unaware of their surroundings or the procedures being performed upon them (Souza, 1995). Indeed, this is the perfect drug. Unfortunately, like all good things,...

Gram Positive And Negative Bacteria
828 wordsGram Positive and Gram Negative Bacteria It is a well-known fact that bacterial cells, like plant cells, are surrounded by a cell wall. However, few people know that their cell walls are quite different. Bacterial cell walls are made up of polysaccharide chains linked to amino acids. At the same time, plant cell walls are made up of cellulose, which contains no amino acids. In the same way, bacterial cell walls themselves differ from one another. Scientists distinguish two types of bacteria cell...

Made Of Proteins Binds To The Small Rna
647 wordsProteins are some of the most essential compounds on the planet. They perform a variety of tasks ranging from muscle contraction to fighting diseases. Over 50 % of the dry weight of organisms are made of proteins; this is because things like your nails and hair are made of proteins. Proteins are also components of biological membranes, and they help regulate the passage of molecules through the membranes. This is all very important to the body, but the most important function, by far, is their u...
