AMP

 
Biochemistry.
a white, crystalline, water-soluble nucleotide, C10H12N5O3H2PO4, obtained by the partial hydrolysis of ATP or of ribonucleic acid, yielding on hydrolysis adenine, ribose, and orthophosphoric acid.
Also called adenosine monophosphate, adenylic acid.

Origin:
1950–55; a(denosine) m(ono) p(hosphate)

Electricity.
1. amperage.
2. ampere; amperes.

am⋅per⋅age

  [am-per-ij, am-peer-]
–noun Electricity.
the strength of an electric current measured in amperes. Abbreviation: amp.
Origin:
1890–95; ampere + -age

am⋅pere

  [am-peer, am-peer]
–noun Electricity.
the base SI unit of electrical current, equivalent to one coulomb per second, formally defined to be the constant current which if maintained in two straight parallel conductors of infinite length, of negligible circular cross section, and placed one meter apart in vacuum, would produce between these conductors a force equal to 2 × 10−7 newton per meter of length. Abbreviation: A, amp.
Also, ampère.

Origin:
1881; named after A. M. Ampère

Amápère /än-per/,André Marie (1775–1836), French physicist. Ampère is credited with founding, naming, and developing the science of electrodynamics. He was the formulator of two lawsin electromagnetism relating magnetic fields to electric currents. The first person to develop techniques for measuring electricity, he invented an instrument that was a forerunner of the galvanometer.In 1881 at the suggestion of Sir Charles Bright, an international congress on electricity adopted ampere as a term for the standard unit of electric current.

Science Dictionary
AMP   (ā'ěm-pē')  Pronunciation Key 
Short for adenosine monophosphate. An organic compound that is composed of adenosine and one phosphate group. It is one of the nucleotides present in DNA and RNA, and is also the fundamental component of ATP and ADP. During certain cellular metabolic processes, AMP forms from ADP when the latter loses a phosphate group, and AMP forms ADP by acquiring a phosphate group. Chemical formula: C10H14N5O7P.
Ampère   (ām'pîr', äm-pěr')  Pronunciation Key 
French mathematician and physicist who is best known for his analysis of the relationship between magnetic force and electric current. He formulated Ampère's law, which describes the strength of the magnetic field produced by the flow of energy through a conductor. The ampere unit of electric current is named for him.

amp

unit of electric current in the Systeme International d'Unites (SI), used by both scientists and technologists. Since 1948 the ampere has been defined as the constant current which, if maintained in two straight parallel conductors of infinite length of negligible circular cross section and placed one metre apart in a vacuum, would produce between these conductors a force equal to 2 10-7 newton per metre of length. Named for the 19th-century French physicist Andre-Marie Ampere, it represents a flow of one coulomb of electricity per second. A flow of one ampere is produced in a resistance of one ohm by a potential difference of one volt. See electric current.
