Flavin mononucleotide
Flavin mononucleotide, also known as riboflavin 5-monophosphate or riboflavine dihydrogen phosphate, is a member of the class of compounds known as flavin nucleotides. Flavin nucleotides are nucleotides containing a flavin moiety. Flavin is a compound that contains the tricyclic isoalloxazine ring system, which bears 2 oxo groups at the 2- and 4-positions. Flavin mononucleotide is practically insoluble (in water) and a moderately acidic compound (based on its pKa). Flavin mononucleotide can be found in a number of food items such as spinach, elliotts blueberry, tea leaf willow, and black mulberry, which makes flavin mononucleotide a potential biomarker for the consumption of these food products. Flavin mononucleotide can be found primarily in blood, as well as throughout most human tissues. Flavin mononucleotide exists in all living species, ranging from bacteria to humans. In humans, flavin mononucleotide is involved in several metabolic pathways, some of which include riboflavin metabolism, pyrimidine metabolism, beta-alanine metabolism, and doxorubicin metabolism pathway. Flavin mononucleotide is also involved in several metabolic disorders, some of which include beta ureidopropionase deficiency, UMP synthase deficiency (orotic aciduria), carnosinuria, carnosinemia, and hypophosphatasia. Moreover, flavin mononucleotide is found to be associated with anorexia nervosa. Flavin mononucleotide (FMN), or riboflavin-5′-phosphate, is a biomolecule produced from riboflavin (vitamin B2) by the enzyme riboflavin kinase and functions as prosthetic group of various oxidoreductases including NADH dehydrogenase as well as cofactor in biological blue-light photo receptors. During the catalytic cycle, a reversible interconversion of the oxidized (FMN), semiquinone (FMNH•) and reduced (FMNH2) forms occurs in the various oxidoreductases. FMN is a stronger oxidizing agent than NAD and is particularly useful because it can take part in both one- and two-electron transfers. In its role as blue-light photo receptor, (oxidized) FMN stands out from the conventional photo receptors as the signaling state and not an E/Z isomerization .

It is the principal form in which riboflavin is found in cells and tissues. It requires more energy to produce, but is more soluble than riboflavin. Flavin mononucleotide belongs to the class of organic compounds known as flavin nucleotides. These are nucleotides containing a flavin moiety. Flavin is a compound that contains the tricyclic isoalloxazine ring system, which bears 2 oxo groups at the 2- and 4-positions. Flavin mononucleotide exists in all living species, ranging from bacteria to humans. Within humans, flavin mononucleotide participates in a number of enzymatic reactions. In particular, formic acid and flavin mononucleotide can be biosynthesized from FMNH2; which is catalyzed by the enzyme lanosterol 14-alpha demethylase. In addition, formic acid and flavin mononucleotide can be biosynthesized from FMNH2 through the action of the enzyme lanosterol 14-alpha demethylase. In humans, flavin mononucleotide is involved in bloch pathway (cholesterol biosynthesis). Outside of the human body, flavin mononucleotide has been detected, but not quantified in several different foods, such as mandarin orange (clementine, tangerine), horseradish tree, black elderberries, angelica, and ostrich ferns.

Lumichrome
Lumichrome, also known as light folinic acid or 7,8-dimethyl-10-ribitylisoalloxazine, is a derivative of riboflavin (vitamin B2). The chemical structure of lumichrome consists of a heterocyclic isoalloxazine ring, which is a fused pyridine and pyrazine ring system. The isoalloxazine ring contains a methyl group at the 7 and 8 positions and is substituted at the 10 position with a ribityl group, which is a 5-carbon chain derived from ribose with a methyl group at the 2’ position. Photocatalytic Activity: Lumichrome exhibits photocatalytic activity and can act as a photosensitizer. It can absorb light energy and transfer it to other molecules, potentially triggering photochemical reactions. Fluorescence: Lumichrome is known for its fluorescence properties. This characteristic makes it useful in various applications, including fluorescence microscopy and as a labeling agent in biological assays. Antioxidant Properties: Lumichrome has been found to have antioxidant properties. It can scavenge free radicals, which may help in protecting cells from oxidative stress. Metabolic Intermediate: In the body, lumichrome can be formed from riboflavin through photochemical or enzymatic degradation. It may play a role in the metabolism of flavins and could be involved in the recycling of flavin cofactors. Potential Biomarker: Due to its presence in biological tissues and its fluorescence properties, lumichrome has been proposed as a potential biomarker for certain diseases and conditions. Plant Pigment: In plants, lumichrome can be involved in light capture and energy transfer processes, although it is not a chlorophyll pigment. It may contribute to the overall light-harvesting capabilities of plant tissues. While lumichrome has several interesting chemical and biological properties, it is not considered an essential nutrient like its parent compound, riboflavin. Its exact role in biological systems is still an area of ongoing research. Lumichrome, a photodegradation product of Riboflavin, is an endogenous compound in humans. Lumichrome inhibits human lung cancer cell growth and induces apoptosis via a p53-dependent mechanism[1][2].
