Smile

A smile is a facial expression formed primarily by flexing the muscles at the sides of the mouth. Some smiles include a contraction of the muscles at the corner of the eyes, an action known as a "Duchenne smile". Smiles performed without the eye contraction can be perceived as "fake".

Among humans, smiling is an expression denoting pleasure, sociability, happiness, or amusement. It is distinct from a similar but usually involuntary expression of anxiety known as a grimace. Although cross-cultural studies have shown that smiling is a means of communication throughout the world, there are large differences between different cultures, with some using smiles to convey confusion or embarrassment.

Historical background

Primatologist Signe Preuschoft traces the smile back over 30 million years of evolution to a "fear grin" stemming from monkeys and apes who often used barely clenched teeth to portray to predators that they were harmless. The smile may have evolved differently among species and especially among humans. Apart from Biology as an academic discipline that interprets the smile, those who study kinesics and psychology such as Freitas-Magalhaes view the smile as an affect display that can communicate feelings such as love, happiness, pride, contempt, and embarrassment.

Smile! (novel)

Smile! is a children's book by Geraldine McCaughrean. In 2004 it won the Nestlé Smarties Book Prize Bronze Award.

Smile (The Beach Boys album)

Smile (occasionally typeset as SMiLE) was a projected album by American rock band the Beach Boys intended to follow their 11th studio album Pet Sounds. After the group's songwriting leader Brian Wilson abandoned large portions of music recorded between 1966 and 1967, the band recorded and released the dramatically scaled-down Smiley Smile album in its place. Some of the original Smile tracks eventually found their way onto subsequent Beach Boys studio and compilation albums. As more fans learned of the project's origins, details of its recordings acquired considerable mystique, and it was later acknowledged as the most legendary unreleased album in the history of popular music.

Working with lyricist Van Dyke Parks, Smile was composed as a multi-thematic concept album, existing today in its unfinished and fragmented state as an unordered series of abstract musical vignettes. Its genesis came during the recording of Pet Sounds, when Wilson began recording a new single: "Good Vibrations". The track was created by an unprecedented recording technique: over 90 hours of tape was recorded, spliced, and reduced into a three-minute pop song. It quickly became the band's biggest international hit yet; Smile was to be produced in a similar fashion. Wilson touted the album "a teenage symphony to God," incorporating a diverse range of music styles including psychedelic, doo-wop, barbershop singing, ragtime, yodeling, early American folk, classical music, and avant-garde explorations into noise and musical acoustics. Its projected singles were "Heroes and Villains", a Western musical comedy, and "Vega-Tables", a satire of physical fitness.

Amp Energy

Amp Energy (or simply Amp) is an energy drink brand produced and owned by PepsiCo. At the time of its introduction in 2001, Amp Energy was initially distributed under the Mountain Dew soft drink brand. Since 2009, it has been produced and labeled under its own stand-alone trademark name. The beverage is packaged in both 16-ounce and 24-ounce cans, and is sold in the United States, Canada and the United Kingdom. As of 2009, Amp Energy was the number four energy drink brand in the U.S. in terms of overall retail sales.

Flavors

The original formulation of Amp Energy was positioned as a flavor extension of the Mountain Dew brand, and in 2001 its label read "Amp Energy Drink from Mountain Dew". In 2008 the label design was changed to contract the product name to a more concise "Amp Energy", with the Mountain Dew logo being shifted to the lower portion of the cans. In Amp's 2011 redesign, the Mountain Dew logo was taken off the cans completely. According to beverage industry commentators at the time, this labeling update was enacted with the intent of "placing a stronger emphasis on the 'Amp Energy' brand and less on its Mountain Dew roots". Amp Energy Original contains taurine, B-vitamins, guarana, ginseng and maltodextrin. 8.4 fluid ounces of Amp contains 74 milligrams of caffeine.

Adenosine monophosphate

Adenosine monophosphate (AMP), also known as 5'-adenylic acid, is a nucleotide that is used as a monomer in RNA. It is an ester of phosphoric acid and the nucleoside adenosine. AMP consists of a phosphate group, the sugar ribose, and the nucleobase adenine. As a substituent it takes the form of the prefix adenylyl-.

Production and degradation

AMP can be produced during ATP synthesis by the enzyme adenylate kinase by combining two ADP molecules:

Or AMP may be produced by the hydrolysis of one high energy phosphate bond of ADP:

AMP can also be formed by hydrolysis of ATP into AMP and pyrophosphate:

When RNA is broken down by living systems, nucleoside monophosphates, including adenosine monophosphate, are formed.

AMP can be regenerated to ATP as follows:

AMP can be converted into IMP by the enzyme myoadenylate deaminase, freeing an ammonia group.

In a catabolic pathway, adenosine monophosphate can be converted to uric acid, which is excreted from the body.

cAMP

AMP can also exist as a cyclic structure known as cyclic AMP (or cAMP). Within certain cells the enzyme adenylate cyclase makes cAMP from ATP, and typically this reaction is regulated by hormones such as adrenaline or glucagon. cAMP plays an important role in intracellular signaling.
