Question

Information about dermatitis vitamin b2 deficiency

Answer 1

Vitamin B12, also called cobalamin, is a water-soluble vitamin that has a key role in the normal functioning of the brain and nervous system, and the formation of red blood cells. It is one of eight B vitamins. It is involved in the metabolism of every cell of the human body, especially affecting DNA synthesis, fatty acid and amino acid metabolism. No fungi, plants, or animals (including humans) are capable of producing vitamin B12. Only bacteria and archaea have the enzymes needed for its synthesis. Some substantial sources of B12 include animal products (shellfish, meat), fortified food products, and dietary supplements. B12 is the largest and most structurally complicated vitamin and can be produced industrially only through bacterial fermentation synthesis, typically used to manufacture B12 for fortified foods and supplements.

Vitamin B12 consists of a class of chemically related compounds (vitamers), all of which show pharmacological activity. It contains the biochemically rare element cobalt (chemical symbol Co) positioned in the center of a planar tetra-pyrrole ring called a corrin ring. The vitamer is produced by bacteria as hydroxocobalamin, but conversion between different forms of the vitamin occurs in the body after consumption.

Answer 2

Riboflavin deficiency (called ariboflavinosis) can appear at intakes of less than 0.5-0.6 mg/day. Too little riboflavin can cause weakness, throat swelling/soreness, a swollen tongue, skin cracking (including cracked corners of the mouth), dermatitis, and anemia.
