Final Answer:
Riboflavin (vitamin B2) is a precursor of the coenzyme FAD, essential for various metabolic reactions. Deficiency symptoms include sore throat, magenta tongue, cheilosis, and conjunctivitis.
Step-by-step explanation:
Riboflavin (vitamin B2) is a precursor of the coenzyme FAD (flavin adenine dinucleotide), which participates in various metabolic reactions, including the citric acid cycle and the metabolism of fats, drugs, and steroids.
Deficiency symptoms of riboflavin include sore throat, redness and swelling of the lining of the throat and tongue (magenta tongue), inflammation and redness of the lining of the mouth (cheilosis), and inflammation and redness of the moist lining of the eye (conjunctivitis).
Riboflavin (vitamin B2) serves as a precursor to the coenzyme FAD, crucial for metabolic reactions like the citric acid cycle. Deficiency may manifest as sore throat, magenta tongue, cheilosis, and conjunctivitis, reflecting its impact on mucous membranes and eye health. Adequate intake supports overall energy metabolism.
