Riboflavin Research Paper
Riboflavin, also known as vitamin B2 is an easily absorbed micronutrient with a key role in maintaining health in humans and animals. It is the central component of the cofactors FAD and FMN, and is therefore required by all flavoproteins. As such, vitamin B2 is required for a wide variety of cellular processes. It plays a key role in energy metabolism, and for the metabolism of fats, ketone bodies, carbohydrates, and proteins. It is also used as an orange-red food colour additive, designated in Europe as the E number E101,[2]
Milk, cheese, leaf vegetables, liver, kidneys, legumes, tomatoes, yeast, mushrooms, and almonds[3] are good sources of vitamin B2, but exposure to light destroys riboflavin.
The name "riboflavin" comes from "ribose"

However, riboflavin deficiency is always accompanied by deficiency of other vitamins.[10]
A deficiency of riboflavin can be primary - poor vitamin sources in one's daily diet - or secondary, which may be a result of conditions that affect absorption in the intestine, the body not being able to use the vitamin, or an increase in the excretion of the vitamin from the body.
In humans, signs and symptoms of riboflavin deficiency (ariboflavinosis) include cracked and red lips, inflammation of the lining of mouth and tongue, mouth ulcers, cracks at the corners of the mouth (angular cheilitis), and a sore throat. A deficiency may also cause dry and scaling skin, fluid in the mucous membranes, and iron-deficiency anemia. The eyes may also become bloodshot, itchy, watery and sensitive to bright light.
Riboflavin deficiency is classically associated with the oral-ocular-genital syndrome. Angular cheilitis, photophobia, and scrotal dermatitis are the classic remembered

Experimental riboflavin deficiency in dogs results in growth failure, weakness, ataxia, and inability to stand. The animals collapse, become comatose, and die. During the deficiency state, dermatitis develops together with hair loss. Other signs include corneal opacity, lenticular cataracts, hemorrhagic adrenals, fatty degeneration of the kidney and liver, and inflammation of the mucous membrane of the gastrointestinal tract. Post-mortem studies in rhesus monkeys fed a riboflavin-deficient diet revealed about one-third the normal amount of riboflavin was present in the liver, which is the main storage organ for riboflavin in mammals. These overt clinical signs of riboflavin deficiency are rarely seen among inhabitants of the developed countries. However, about 28 million Americans exhibit a common ‘sub-clinical’ stage.[11] characterized by a change in biochemical indices (e.g. reduced plasma erythrocyte glutathione reductase levels). Although the effects of long-term subclinical riboflavin deficiency are unknown, in children this deficiency results in reduced growth. Subclinical riboflavin deficiency has also been observed in women taking oral contraceptives, in the elderly, in people with eating disorders, and in disease states such as HIV, inflammatory bowel disease, diabetes and chronic heart disease. The fact that riboflavin deficiency does not immediately lead to gross

    2) The Indian cultures of the New World had several common characteristics but also some differences that made them unique. A main common quality of the Indians is that they all depended on the cultivation of corn. The timing that corn cultivation reached their cultures reflected their development. Most of the Indian tribes were all small, scattered, and impermanent settlements. However there were a few exceptions, such as the Aztecs who prospered greatly in number and also the Creek, Choctaw, and Cherokee, whose population grew in favor to the “three-sister” farming technique. In addition, most cultures were matrilineal: power and possessions passed down on the female side. Lastly, the Indian cultures all revered the physical and natural world with spiritual properties and had no desire to manipulate in aggressively. Yet, there were unique characteristics of the different Indian tribes that existed. For example, the Iroquois developed strong political and organizational skills that led to powerful military alliances that other Indian tribes and the colonists had to deal with later on.…

    There are eight vitamins in the B-complex family and they include thiamine, riboflavin, niacin, vitamin B6, foliate, vitamin B12, biotin and pantothenic acid. B complex vitamins are commonly known as “energy vitamins” because they are vital to metabolism and the body’s ability to convert food into energy. These vitamins are also important for the nervous and immune systems to function properly, and play an important role in the production of enzyme as well. Sources of B complex vitamins are available through various foods such as whole grains, salmon, peanuts, green leafy vegetables, and milk.

    Thiamine is a B vitamin crucial in the body’s metabolism of glucose and amino acids. Thiamine-responsive MSUD is the least severe form of the disease. People with this variation of the disease can tolerate a diet more rich in protein due to the fact that there is some BCKCD activity. Treatment of this subtype includes a daily dose of Vitamin B1 (thiamine). Medical literature suggest the first person to be diagnosed with thiamine-responsive MSUD was a Canadian infant who was found to have increased levels of branched chain amino acids in her blood. The infant was started on thiamine and showed reduced levels of branched chain amino acids. Upon cessation of treatment the patient’s BCAA levels were shown to be once again elevated. The patient was again started on thiamine at which time BCAA levels fell to an acceptable…
