Document Summary
*thiamin not involved in carrying out hydrogen or electrons (only in transketolase, carboxylase etc) Riboflavin involved in redox reactions (reduction) ribose 5 carbon sugar. *riboflavin has flavin ring and ribose on right side (5 c); coenzyme flavokinase, use atp adp and mg or mn. Energy is consumed in reaction and atp becomes adp; phosphate is added onto ribose coenzyme flavin mononucleotide (fmn), use atp ppi and produces final coenzyme fad (by fad synhtetase) *ribose + phosphate= nucleotide flavin adenine dinucleotide (fad) Amp added onto fmn (fmn= flavin + ribose+ phosphate) 2 nucleotides. *dairy, grains & meats milk, milk products, eggs, meat, legumes. **riboflavin is sensitive to lights lose 50% of nutrient after sitting out in clear glass bottle for 2 hours. **riboflavin has a high affinity to the proteins; riboflavin will not be available unless we digest the proteins first. *when attached to proteins, it is released by hcl (stomach acid), pepsin or pancreatic proteases.
