When the drug penicillin finds the bacteria, penicillin blocks the bacteria's ability to produce this chemical, making it impossible for the bacteria to perform respiration. Numerous other drugs have been derived from penicillin and are referred to as sulfa drugs.
When the goal is to prevent certain bodily functions and reactions from taking place, the drugs used are called hormones. The most commonly used hormones are for birth control. There are two chemical components to birth control hormones. The first chemical synthesizes the natural hormone known as estrogen. When high levels of this hormone are introduced into the body, the body reads the hormone and assumes it is pregnant. The result is that the body does not allow implantation. The second chemical used to copy natural hormones is progesterone. Progesterone within the body triggers ovulation. When mimicked using chemicals, the body does not ovulate (Lide, 70). When these two artificial hormones combine, it effectively eliminates the natural process of fertility by communicating to the body that it is pregnant. While effective, hormones have undergone increased scrutiny due to numerous side effects the drugs can cause including breast cancer in some patients.
Steroids alter the hormonal balance within the body to achieve certain desired outcomes. The main ingredient in steroids is the hormone testosterone. One such steroid, anabolic steroids, decreases the amount of testosterone within the body. The steroid structure is highly complex, being composed of a 17-carbon-atom, with a four ring skeletal structure. If used properly and within the recommended limits, steroids act to reduce inflammation and aid in healing. When abused, steroids can cause liver damage and cause a shortage of other hormones resulting in undesired outcomes (The Journal of Steroid Biochemistry).
Anticancer drugs, or cytotoxicity drugs, are chemically attracted to and poisonous toward cancer cells within the body. Selective toxicity is achieved through the chemical structure of the drugs. For instance, hexamethylmalamine, or Trimelamol, actively seeks out and destroys...
They are compounds that have carbon, hydrogen and oxygen. There are 3 forms of carbohydrates. First are the monosaccharides which are simple sugars. They have simple structures in the ration of 1:2:1. They usually contain 5-6 atoms of carbon arranged in a 5-6 member ring. Oligosaccharides are monosaccharides which are combined in short strings that are linked together through dehydration synthesis. Sucrose is one of the oligosaccharides. It is
The entire unit is known as a photosytem and in green plants, one finds two of these systems, photosystem I and photosystem II, both of which are involved in the light reactions of photosynthesis. Light energy absorbed by these pigments of the antenna complex is "passed to the reaction center chlorophyll molecules from which it passes along an electron-transport chain" (Blankenship, 215). Photosystems II contains a kind of chlorophyll a
Chemistry Based on the fact that our class focuses on atoms, atomic structure, chemical bonds, nuclear chemistry (radioactivity, nuclear equation, half life, radio isotopes, artificial transmutation, etc.), this article review aims to provide a summary of a related story named "IBM Scientists First to Image the 'Anatomy' of a Molecule; Imaging Individual Atoms Within A Molecule Has Been A Long-standing Goal of Surface Microscopy" by the IBM press team in the
Chemistry and Recreational Drugs The objective of this study is to examine chemistry as it relates to recreational drugs. Toward this end, this study will review literature in this area of inquiry and report on the same. Recreational drugs refer to drugs such as marijuana, methamphetamine, ecstasy, cocaine, and other such drugs. The chemistry of each of these recreational drugs is unique and each cause specific effects to the individual taking these
Chemistry The Many Dimension of Red Red is one of the oldest colors known to humans. It is a color that carries with it significant emotional meanings. Red occurs in nature on Earth and in the cosmos. It is a dynamic color affecting people and animals. The paper will explore the history of the color red with regard to its chemical properties, natural history, and cultural significance. The study of color proves
Chemistry The Prosperous Autobiography of Phosphorus Greetings humans, this message is from your friend, Phosphorus. That's Phosphorus with a "-us" and not an "-ous" and it is often misspelled. I am an element, not an adjective. You may not be unaware of the special connection you have with me, but it exists nonetheless. For you see, I, Phosphorus, am "an essential component of living systems and is found in nervous tissue, bones
