    YouTube Premium (formerly YouTube Red) is a paid streaming subscription service that provides advertising-free streaming of all videos hosted by YouTube, exclusive original content produced in collaboration with the site's major creators, as well as offline playback and background playback of videos on mobile devices. The service was originally launched in November 2014 as Music Key, offering only ad-free streaming of music and music videos from participating labels on YouTube and Google Play Music. The service was then revised and relaunched as YouTube Red on October 31, 2015, expanding its scope to offer ad-free access to all YouTube videos, as opposed to just music. YouTube announced the rebranding of the service as YouTube Premium on May 17, 2018, alongside the return of a separate, YouTube Music subscription service.

  • Hydrophobicity scales

    serch.it?q=Hydrophobicity-scales

    Hydrophobicity scales are values that define relative hydrophobicity of amino acid residues. The more positive the value, the more hydrophobic are the amino acids located in that region of the protein. These scales are commonly used to predict the transmembrane alpha-helices of membrane proteins. When consecutively measuring amino acids of a protein, changes in value indicate attraction of specific protein regions towards the hydrophobic region inside lipid bilayer.
