Beriberi

Question: What enzyme would be affected by beriberi or the lack of thiamine?

Answer: Thiamine is one of the B vitamins and plays an important role in energy metabolism and tissue building. It combines with phosphate to form the coenzyme thiamine pyrophosphate (TPP), which is essential in reactions that produce energy from glucose or that convert glucose to fat for storage in the tissues. When there is not enough thiamine in the diet, these basic energy functions are disturbed, leading to problems throughout the body.

Question: What enzymes and metabolic reactions would be slowed in an individual with Beriberi disease? And which products would accumulate?

Answer: Beriberi disease is caused by a thiamine (vitamin-B) deficiency. The biologically useful form of thiamine is called TPP or thiamine pyrophosphate (or TDP- thiamine diphosphate), and it is used in biological processes, like the Krebs Cycle and the Pentose Phosphate Pathway. Thiamine pyrophosphate (TPP) is a coenzyme for pyruvate dehydrogenase, α-ketoglutarate dehydrogenase and transketolase. The first two of these enzymes function in the metabolism of carbohydrates, while transketolase functions in the pentose phosphate pathway to synthesize NADPH and the pentose sugars deoxyribose and ribose. TPP is synthesized by the enzyme thiamine pyrophosphokinase, which requires free thiamine, magnesium, and adenosine triphosphate. It is yet unclear exactly how thiamine plays a role in neurological function, but it is found in nerves and in the brain and the lack of it causes neurological disorders.

Question: How many people suffer from Beriberi? I don't care if it's how many in a year, how many a day, how many since it came about. Or if somebody just has a rough estimate using there common sense? Please answer as soon as you can Really important

Answer: Japan, Malaysia, Philippines,Indonesia.Beriberi is now confined to the poorest areas of South East Asia.It ravaged people of all ages in Asia ------------ The name "beriberi" originated in Southeast Asia, where it had become widespread with the colonial introduction of machine milling of rice. Work on the disease was done by the Dutch in Java, most notably by Christiaan Eijkman, who shared the 1929 Nobel prize for studies using chickens, and by the British in Malaysia and the Americans in the Philippines. Some kind of consensus was reached at the first meetings of the Far Eastern Association of Tropical Medicine in 1910 and 1912. http://dannyreviews.com/h/Beriberi.html ---------- Beriberi puzzled medical experts for years as it ravaged people of all ages in Asia. Doctors thought it was caused by something in food. Not until the early 1900s did scientists discover that rice bran, the outer covering that was removed to create the polished white rice preferred by Asians, actually contained something that prevented the disease. Thiamine was the first vitamin identified. In the 1920s, extracts of rice polishings were used to treat the disease.http://www.answers.com/topic/beriberi "White rice can be poisonous!" This was the conclusion Christiaan Eijkman declared in 1896 on his return to the Netherlands, after ten years of research in Batavia, Java in the Dutch East Indies (now Jakarta, Indonesia).http://nobelprize.org/educational_games/… ------ Beriberi is now confined to the poorest areas of South East Asia. It can be prevented by eating undermilled or par-boiled rice, or by fortification of rice with thiamine. Probably the most important factor in the reduction of beriberi is the general increase in overall food consumption so that the staple diet is varied and contains legumes and pulses, which contain a large amount of thiamin. http://www.online-vitamins-guide.com/def…

Question: help me find the answers of the strange case of beriberi worksheet? the worksheet looks like this: Scientific Method In Action The Strange Case of BeriBeri In 1887 a strange nerve disease attacked the people in the Dutch East Indies. The disease was beriberi. Symptoms of the disease included weakness and loss of appetite, victims often died of heart failure. Scientists thought the disease might be caused by bacteria. They injected chickens with bacteria from the blood of patients with beriberi. The injected chickens became sick. However, so did a group of chickens that were not injected with bacteria. One of the scientists, Dr. Eijkman, noticed something. Before the experiment, all the chickens had eaten whole-grain rice, but during the experiment, the chickens were fed polished rice. Dr. Eijkman researched this interesting case. he found that polished rice lacked thiamine, a vitamin necessary for good health. 1.

Answer: 1. What causes beriberi?

Question: what can beriberi do to el human body?

Answer: Beriberi is a lack of Thiamin (vitamin B-1)which is a water-soluble and heat-labile vitamin that acts as a coenzyme in the decarboxylation (pyruvate and ketoglutarate) and transketolation pathways (pentose phosphate pathway) of carbohydrate metabolism, and possibly in nerve conduction (essential for the synthesis of acetylcholine). Beriberi was first describe some 4500 years ago, but the relation with B1 has been manifested in the last century. The biochemical defect responsible for the clinical manifestations of beriberi is not known. Deficiency of this vitamin affects the cardiovascular, muscular, gastrointestinal, and nervous systems. Beriberi does not occur in the US or western countries but Vit. B 1 (thiamine) deficiencies are related to heavy alcohol abuse or HIV infections.

Question: What are the most common vitamin and mineral deficiencies in Western diet? So on one hand we need all the vitamins and minerals, and on the other I haven't seen that many people with scurvy or beriberi, so at least some must be extremely plentiful in our food. So which vitamin and mineral deficiencies are actually common in people following Western diet, and which we don't need to concern ourselves about?

Answer: I swear to god I was suffering from scurvy, or at least Vitamin C deficiency. I had incredible cravings for broccoli, orange juice, pineapple on pizza, potatoes. Even though citrus flavored sodas didn't have Vitamin C, I gulped them down. I wanted to live every day just eating burgers and hot dogs though. I felt like crap everyday. I'm eating fruits now everyday, and I'm getting better. I feel better already, and the cravings have gone away.

Question: What is the difference between vitamins and minerals? Which vitamins are antioxidants? Which vitamins are fat-soluble? Which each of the following indicate the correct vitamin needed: a. sunshine vitamin b. beriberi c. rickets d. scurvy 6. What is the difference between complete and incomplete protein? 7. What percent of calories should come from fat in a healthy diet? 8. Nutrition Facts on most labels are based on a diet that contains what calories? 9. What mineral is most abundant in your body? 10. What other minerals and vitamins work with it to give you strong bones and teeth? 11. What mineral produces hemoglobin and prevents anemia? 12.What are trace minerals? 13. What colors are foods high in vitamin "A"? 15. What is the mineral most often linked with high blood pressure? 16. Give three other names for fiber 17. What type of gas do most leavening agents produce? 18. Is butter a plant or animal product? 19. Is oil heavier or lighter than water?

Answer: Getting to your main question, vitamins and minerals are different. Vitamins ("vita" = life and "amine" = containing nitrogen) are organic (containing carbon, which is an element found in all living things) compounds (containing atoms of one or more different elements). Minerals are pure inorganic elements (containing atoms of the same element), meaning they are much simpler in chemical form than vitamins. All vitamins are essential or required by our bodies, whereas only some minerals are essential nutrients. Vitamins are vulnerable to heat, light, and chemical agents, so cooking, food preparation, processing, and storage must be appropriate to preserve vitamins in food. Minerals, on the other hand, are more stable to food preparation, but mineral loss can occur when they are bound to other substances in foods (such as oxalates found in spinach and tea, and phytates found in legumes and grains), making them unavailable for the body to utilize.

Question: How many people are sick and how many healthy? The island of Beriberi (population 4000) has endemic "Poe's revenge," which carries no immunity. Measuring population in thousands and time in days, the rate at which healthy people (S) become ill (L) is 0.1SL, while the rate at which ill folk recover is .03L. At equilibrium, how many people are sick and how many healthy?

Answer: Hi, Let x = number of people who are ill Then 4000 - x are healthy If .1 of the healthy people get sick while .3 of the sick people become healthy, then .9 healthy + .3 sick recover = .7sick + .1 healthy becoming sick .9(4000 - x) + .3x = .7x + .1(4000 - x) 3600 - .9x + .3x = .7x + 400 - .1x 3200 = 1.2x x = 2667 As they approach equilibrium, 2667 are sick and 1333 are healthy so when .1 of the healthy people become sick and .3 of the sick people get healthy, they hit equilibrium at 2000 people in each category. I hope that helps!! :-)
