Proteins

Proteins (/ˈproʊˌtiːnz/ or /ˈproʊti.ᵻnz/) are large biomolecules, or macromolecules, consisting of one or more long chains of amino acidresidues. Proteins perform a vast array of functions within living organisms, including catalyzing metabolic reactions, DNA replication,responding to stimuli, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of […]

Hydrogen atom

In 1914, Niels Bohr obtained the spectral frequencies of the hydrogen atom after making a number of simplifying assumptions. These assumptions, the cornerstones of the Bohr model, were not fully correct but did yield the correct energy answers. Bohr’s results for the frequencies and underlying energy values were confirmed by the full quantum-mechanical analysis which uses the Schrödinger […]
