Folic acid, also known as vitamin B9, is a water-soluble vitamin that plays several important roles in the body. It is required for cell growth and DNA synthesis, and is especially important during periods of rapid cell division and growth like infancy and pregnancy. A deficiency in folic acid can lead to megaloblastic anemia and neural tube defects in newborns if a woman is deficient during pregnancy. Good dietary sources include leafy green vegetables, beans, oranges, and fortified grains.

Riboflavin, also known as vitamin B2, is a vitamin found in food and sold as a dietary supplement.[3] It is essential to the formation of two major coenzymes, flavin mononucleotide and flavin adenine dinucleotide. These coenzymes are involved in energy metabolism, cellular respiration, and antibody production, as well as normal growth and development. The coenzymes are also required for the metabolism of niacin, vitamin B6, and folate. Riboflavin is prescribed to treat corneal thinning, and taken orally, may reduce the incidence of migraine headaches in adults.
Riboflavin deficiency is rare and is usually accompanied by deficiencies of other vitamins and nutrients. It may be prevented or treated by oral supplements or by injections. As a water-soluble vitamin, any riboflavin consumed in excess of nutritional requirements is not stored; it is either not absorbed or is absorbed and quickly excreted in urine, causing the urine to have a bright yellow tint. Natural sources of riboflavin include meat, fish and fowl, eggs, dairy products, green vegetables, mushrooms, and almonds. Some countries require its addition to grains.
Riboflavin was discovered in 1920, isolated in 1933, and first synthesized in 1935. In its purified, solid form, it is a water-soluble yellow-orange crystalline powder. In addition to its function as a vitamin, it is used as a food coloring agent. Biosynthesis takes place in bacteria, fungi and plants, but not animals. Industrial synthesis of riboflavin was initially achieved using a chemical process, but current commercial manufacturing relies on fermentation methods using strains of fungi and genetically modified bacteria.

A brief information about the SCOP protein database used in bioinformatics.
The Structural Classification of Proteins (SCOP) database is a comprehensive and authoritative resource for the structural and evolutionary relationships of proteins. It provides a detailed and curated classification of protein structures, grouping them into families, superfamilies, and folds based on their structural and sequence similarities.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
2. INTRODUCTION
Vitamin B9 also called folate or folic acid, is one of
8 B vitamins. All B vitamins help the body convert
food into fuel, which is used to produce energy.
Folic acid is the synthetic form of B9, found in
supplements and fortified foods ,while folate
occurs naturally in foods.
3. DEFINITION
The word of folic acid is derived from latin word
folium means leaf and it is also isolated leafy
vegetable spinach.
Folic acid is water soluble vitamin, folic acid itself
not biologically active but its biological importance
is due to Tetrahydrofolate and other derivatives.
4. ACTIVE FORM
Tetrahydrofolate(THF or FH 4) is the active form of
folic acid.
Folic acid mainly consist of three components,
1.Pteridine ring
2.PABA
3.Glutamic acid residue
Folic acid mostly has one glutamic acid residue and
its known as pteroyl- glutamic acid(PGA).
5.
6. PHYSICAL AND CHEMICAL
PRPOPERTIES
Folic acid appears as odorless orange-yellow needles.
Folic acid is water soluble vitamin, meaning the body
does not store them.
Odorless; Tasteless;
Molecular Formula is C19H19N7O6
Molecular weight is 441.4.
7. BIOSYNTHESIS
Animals, including humans, cannot
synthesize folate and therefore must obtain
folate from their diet.
All plants and fungi and certain protozoa,
bacteria can synthesize folate de novo
through variations on the same biosynthetic
pathway.
8. The folate molecule is synthesized from pterin
pyrophosphate, para-aminobenzoic acid, and
glutamate through the action of dihydropteroate
synthase and dihydrofolate synthase.
Pterin is in turn derived in a series of
enzymatically catalyzed steps from guanosine
triphosphate (GTP), while para-aminobenzoic
acid is a product of the shikimate pathway.

10. Tetrahydrofolate the enzyme of folic acid, is
actively involved in one carbon metabolism.
THF serves as an acceptor or donor unit in a
variety if reactions involving amino acids and
nucleotide metabolism.
The one carbon unit binds with THF at
position N5 or N10 of pteroyl structure.
13. Folate is needed to help our cells grow and
multiply, which makes it a key vitamin in
periods of rapid growth and development,
such as pregnancy and infancy.
Folate is particularly important to help
develop the baby’s skull and spinal cord,
which is why low levels of this vitamin,
before and during pregnancy, can lead to
severe birth defects, called neural tube
defects.
14. Folate and vitamin B12 share many functions in
the body. For example, they both work together to
create our genetic material (DNA), form healthy
red blood cells and support the normal
functioning of our brain and nervous system.
Both vitamins, alongside vitamin B6, also
collaborate in the breaking down of
homocysteine, an amino acid that can put us at
higher risk of cardiovascular disease, when
present in high amounts.
18. THERAPEUTIC USES
Prevention of certain birth defects.
Make healthy red blood cells.
Treat anemic condition in both adults and children.
Acts by helping the body produce and maintain
new cells.
Folate is also important for the synthesis and repair
of DNA and other genetic material, and its
necessary for cells to divide.
