Question

Identify the roles of thiamin, riboflavin, and niacin in energy metabolism and other body functions. pleas type it at least 10 sentences

Answer 1

Answer - The roles of thiamin, riboflavin, and niacin in energy metabolism and other body functions------

• (1)-Thiamin, riboflavin, niacin are required for decarboxylation, transmutation, acylation, oxidation and reduction of substrates that ultimately used in energy consumption. One or more major of these are also important for amino acids, fatty acids, cholesterol, steroids and glucose synthesis.
• (2) - In fact, thiamin plays a critical role in the energy metabolism and therefore in the growth, development and function of cell.
• (3) - Although thiamin deficiency is not usual in developed countries, because it is contained in breads, cereals, pulses, meat, liver, fish and some fortified foods.
• (4)- The existence of thiamin deficiency has been observed in more than half of the elderly people who require nursing care.
• (5)-Riboflavin is an essential component of two coenzymes that play major roles in energy production, cellular function, growth and development, and metabolism of fat, drugs and steroids.
• (6)- Riboflavin deficiency is extremely rare in developed countries because its sources are commonly consumed foods (milk and milk drinks, bread and bread products, mixed foods whose main ingredients is meat, ready to eat, cereals and bread products, mixed foods whose main ingredients is meat, ready to eat cereals and bread products, mixed foods whose main ingredients is meat, ready to eat cereals and mixed foods whose main ingredients is grain).
• (7) However, adolescents are at a high risk for nutrional deficiencies because of their notoriously poor dietary habits, and the estimation of riboflavin deficiency may be an indicator of the overall nutritional status.
• (8)- The function of niacin in human body is precursor of the nicotinamide nucleotide coenzymes NAD and NADP . NAD is essential for energy - producing reactions and NADP for anabolic reactions. Moreover, NAD also participates in unique non-redox adenosine diphosphate ribose transfer reactions that are involved in protein modification, calcium mobilization, cell signaling, and DNA repair.

--Thiamin, riboflavin niacin are essential micronutrients are are involved in energy metabolism, they may prevent the occurance of devepmental abnormalities and chronic degenerative and Chornic degenerative neoplastic disease.
