The term lipid refers to a broad category of molecules, which serve a wide range of purposes in nature. Lipids tend to be hydrophobic in nature but there are also lipids that are amphiphilic as well. It is this characteristic that allows these group of structures to serve a range of functions. In the human body there some important lipids include glycerolipids, glycerophospholipids, and sterols, and sphingolipids. Glycolipids are important as they serve as the body’s way of storing energy. Glycerphospholipids

The goal of eugenics is to racially cleanse and create a population with pure blood excluding the tainted blood of the unfit. Eugenics according to Calum MacKellar and Christopher Betchel, “is a general enhancement of humanity.” Dorthy Porter in Darwinian Disease Archaeology states, “Eugenics is the study of human hereditary in order to manipulate human breeding to influence evolutionary ‘progress.’” Although there are advantages to eugenics, there are numerous more negatives. Eugenics can not only

Tay Sach’s Disease The body is a very diverse and complex system. Tay-Sachs disease can be a very scary but rare illness. Tay-Sach’s is a genetic disease which causes destruction to vital body systems, such as the brain and spinal cord. The invisible disease at first, begins within the fetus at early stages of pregnancy. Up until the age of 6 months, this death causing disease is imperceptible. A simple definition of Tay-Sachs disease is the malfunction of the lysosomes (organelle that removes cell

Prevention is the greatest protection A few years ago, my neighbor got married and was ready to have a baby. Unfortunately, he and his wife’s pre-pregnancy check showed that they had a thalassemia gene, and if they gave birth to a child, the child was likely to die because of severe thalassemia. Although they want to have a child belonging to themselves, they finally chose to adopt a child. Thalassemia is a common genetic disease in my province, the local government calls on all couples to accept

Introduction Tay-Sachs disease got its name from Warren Tay and Bernard Sachs. Warren Tay was a British ophthalmologist who first discovered a cherry-red spot on the retina of the eye. Bernard Sachs was a neurologist from New York who later discovered and described the cellular changes of the disease. Not only did Sachs become the first person to recognize the cellular changes, but he was also able to see that the disease was most common amongst families . Genetic Component Approximately 1.2 million

Tay-Sachs disease is a human genetic abnormality that results in cells accumulating and becoming clogged with very large and complex lipids. Which cellular organelle must be involved in this condition? A) the Golgi apparatus
B) the lysosome
C) membrane-bound ribosomes D) mitochondria E) the endoplasmic reticulum In the most simplistic explanation, lipids are synthesized in the smooth endoplasmic reticulum, transferred to the Golgi apparatus to be changed and sorted, and then they can be released

Eugenics is defined, in some way or the other, as the process of reshaping the human race by determining the kinds of people who will be born. As such, there is much debate in the field of eugenics, with authors, like Philip Kitcher, who support laissez-faire or a minimalist approach of eugenics in which eugenic decision-making should be limited only to avoid neurological illnesses and in which parental free choice is valued. Gregory Stock’s essay, The Enhanced and Un-Enhanced, presents otherwise

Tay-Sachs disease was one of the first choices that came to mind since it is one of many diseases associated with Ashkenazi Jews (Jews of Eastern European descent). Tay-Sachs is a deadly heritable disease caused by the absence or mutation of Hex- A, an enzyme that breaks down complex fats called gangliosides found in nervous tissue. Without Hex- A, there is a buildup of gangliosides in the cells of the brain, causing major damage to the cells (“Learning About Tay-Sachs Disease”). Tay-Sachs is an

“The carrier rate for Tay-Sachs in the general population is 1/600” (OMIM). Sandhoff Disease is a rare genetic disorder, and it is a severe form of Tay-Sachs that progressively destroys cells in the brain and spinal cord. Since its discovery and analysis of inheritance, there have been advancements of its diagnosis, treatment, research, and its support resources for affected families. Those affected individuals lose motor skills and function of other body parts. As the disease progresses they experience

Tay Sachs is an incurable genetic disease that affects the central nervous system. It is a rare disorder that occurs chiefly in infants and children, especially those of the Jewish heritage. It is characterized by a red spot in the retina, paralysis, gradual blindness, and loss of muscle movement. Tay Sachs can only be inherited, which means it is passed from parents to child only. The process begins in the fetus, very early in pregnancy. However, the disease does not become physically apparent
