Yellow
Yellow is the color between green and orange on the spectrum of light. It is evoked by light with a dominant wavelength of roughly 575585 nm. It is a primary color in subtractive color systems, used in painting or color printing. In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color made by combining red and green at equal intensity. Carotenoids give the characteristic yellow color to autumn leaves, corn, canaries, daffodils, and lemons, as well as egg yolks, buttercups, and bananas. They absorb light energy and protect plants from photo damage in some cases. Sunlight has a slight yellowish hue when the Sun is near the horizon, due to atmospheric scattering of shorter wavelengths (green, blue, and violet). Because it was widely available, yellow ochre pigment was one of the first colors used in art; the Lascaux cave in France has a painting of a yellow horse 17,000 years old. Ochre and orpiment pigmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blond
Blond () or blonde (), also referred to as fair hair, is a human hair color characterized by low levels of eumelanin, the dark pigment. The resultant visible hue depends on various factors, but always has some yellowish color. The color can be from the very pale blond (caused by a patchy, scarce distribution of pigment) to reddish "strawberry" blond or golden-brownish ("sandy") blond colors (the latter with more eumelanin). Occasionally, the state of being blond, and specifically the occurrence of blond traits in a predominantly dark or colored population are referred to as blondism. Because hair color tends to darken with age, natural blond hair is significantly less common in adulthood. Naturally-occurring blond hair is primarily found in people living in or descended from people who lived in Northern Europe, and may have evolved alongside the development of light skin that enables more efficient synthesis of vitamin D, due to northern Europe's lower levels of sunlight.

Subrius Flavus
Subrius Flavus was a tribune of the Praetorian Guard who was heavily implicated in the Pisonian conspiracy against the emperor Nero and was executed in 65 CE for his involvement. Role in the Pisonian Conspiracy As Tribune and a man of military experience, Flavus enjoyed great significance in the plot. Along several others, including the Centurion Sulpicius Asper, Flavus is described as one of the conspiracy's "leading lights" by Tacitus. He was close to Gaius Calpurnius Piso, the figurehead of the conspiracy. Tacitus observes that Flavus' hatred for Nero arose suddenly while he was watching him perform on stage but failed to attack him in front of the audience because he would not have had a chance to escape. Tacitus also observes that it was rumoured that, after the success of the conspiracy, Flavus intended to murder Piso and give control over the empire to Seneca the Younger, a fellow conspirator, because "it mattered not as to the disgrace if a harp-player were removed and ...

Flavius
The gens Flavia was a plebeian family at ancient Rome. Its members are first mentioned during the last three centuries of the Republic. The first of the Flavii to achieve prominence was Marcus Flavius, tribune of the plebs in 327 and 323 BC; however, no Flavius attained the consulship until Gaius Flavius Fimbria in 104 BC. The gens became illustrious during the first century AD, when the family of the Flavii Sabini claimed the imperial dignity.''Dictionary of Greek and Roman Biography and Mythology'', vol. II, p. 169"Flavia Gens". Under the Empire, the number of persons bearing this nomen becomes very large, perhaps due to the great number of freedmen under the Flavian dynasty of emperors. It was a common practice for freedmen to assume the nomina of their patrons, and so countless persons who obtained the Roman franchise under the Flavian emperors adopted the name ''Flavius'', which was then handed down to their descendants. Freedmen under the Constantinian dynasty, whose me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flavin Group
Flavins (from Latin ''flavus'', "yellow") refers generally to the class of organic compounds containing the tricyclic heterocycle isoalloxazine or its isomer alloxazine, and derivatives thereof. The biochemical source of flavin is the yellow B vitamin riboflavin. The flavin moiety is often attached with an adenosine diphosphate to form flavin adenine dinucleotide (FAD), and, in other circumstances, is found as flavin mononucleotide (or FMN), a phosphorylated form of riboflavin. It is in one or the other of these forms that flavin is present as a prosthetic group in flavoproteins. Despite the similar names, flavins (with "i") are chemically and biologically distinct from the flavanoids (with "a"), and the flavonols (with "o"). The flavin group is capable of undergoing oxidation-reduction reactions, and can accept either one electron in a two-step process or two electrons at once. Reduction is made with the addition of hydrogen atoms to specific nitrogen atoms on the isoall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flavonoid
Flavonoids (or bioflavonoids; from the Latin word ''flavus'', meaning yellow, their color in nature) are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans. Chemically, flavonoids have the general structure of a 15-carbon skeleton, which consists of two phenyl rings (A and B) and a Heterocyclic compound, heterocyclic ring (C, the ring containing the embedded oxygen). This carbon structure can be abbreviated C6-C3-C6. According to the IUPAC nomenclature, they can be classified into: *flavonoids or bioflavonoids *isoflavonoids, derived from 3-phenylchromone, chromen-4-one (3-phenyl-1,4-benzopyran, benzopyrone) structure *neoflavonoids, derived from 4-phenylcoumarin (4-phenyl-1,2-benzopyran, benzopyrone) structure The three flavonoid classes above are all ketone-containing compounds and as such, anthoxanthins (flavones and flavonols). This class was the first to be termed bioflavonoids. The terms flavonoid and bioflavo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flavoprotein
Flavoproteins are proteins that contain a nucleic acid derivative of riboflavin. These proteins are involved in a wide array of biological processes, including removal of radicals contributing to oxidative stress, photosynthesis, and DNA repair. The flavoproteins are some of the most-studied families of enzymes. Flavoproteins have either FMN ( flavin mononucleotide) or FAD ( flavin adenine dinucleotide) as a prosthetic group or as a cofactor. The flavin is generally tightly bound (as in adrenodoxin reductase, wherein the FAD is buried deeply). About 5-10% of flavoproteins have a covalently linked FAD. Based on the available structural data, FAD-binding sites can be divided into more than 200 different types. 90 flavoproteins are encoded in the human genome; about 84% require FAD and around 16% require FMN, whereas 5 proteins require both. Flavoproteins are mainly located in the mitochondria. Of all flavoproteins, 90% perform redox reactions and the other 10% are transferases ...
