Dalton vs. Kilodalton — What's the Difference?

A unit used in expressing the molecular weight of proteins, equivalent to atomic mass unit.

A unit of mass equal to 1,000 atomic mass units.

See atomic mass unit.

An atomic mass unit equal to 1,000 daltons; usually used to describe the molecular weight of large molecules such as proteins.

(physics) the atomic mass unit

John Dalton, scientist, born 1766, died 1844.

A unit of mass, approximately 1.66 x 10-24 grams; - it is approximately equal to the mass of one hydrogen atom, but the exact value differs slightly as used in physics and chemistry. It is used mostly to describe the size of proteins and nucleic acids in biochemistry.

English chemist and physicist who formulated atomic theory and the law of partial pressures; gave the first description of red-green color blindness (1766-1844)
