Glossitis linear or patchy red lesions. Vitamin B1 deficiency (thiamin deficiency) can cause glossitis. Vitamin B2 deficiency (ariboflavinosis) can cause glossitis, along with angular cheilitis, cheilosis, peripheral neuropathy and other signs and symptoms. The glossitis in vitamin B2 deficiency is described as magenta. Vitamin B3 deficiency (pellagra) can cause glossitis. Vitamin B6 deficiency (pyridoxine deficiency) can cause glossitis, along with angular cheilitis, cheilosis, peripheral neuropathy and seborrheic dermatitis. Folate deficiency (vitamin B9 deficiency) can cause glossitis, along with macrocytic anemia, thrombocytopenia, leukopenia, diarrhea, fatigue and possibly neurological signs. Apart from pernicious anemia discussed above, any other cause of vitamin B12 deficiency
Vitamin D the transformation of previtamin D to vitamin D in an organic solvent takes about 12 days to complete. The conversion of previtamin D to vitamin D in the skin is about 10 times faster than in an organic solvent. The conversion from ergosterol to vitamin D follows a similar procedure, forming previtamin D by photolysis, which isomerizes to vitamin D. The transformation of previtamin D to vitamin D in methanol has a rate comparable to that of previtamin D. The process is faster in white button mushrooms. Vitamin D is produced photochemically from 7-dehydrocholesterol in the skin of most vertebrate
