Biochemistry

Definition

Biochemistry is the study of the structure and function of biological molecules such as proteins, nucleic acids, carbohydrates and lipids. Biochemistry is also used to describe techniques suited to understanding the interactions and functions of biological molecules, including traditional techniques such as Western blotting, co-immunoprecipitation, and chromatography methods.

    Sphingolipids are a major class of lipids, comprising various species with diverse functions. In addition to being structural elements of membranes, many sphingolipids are bioactive and regulate a myriad of cellular processes. Recent advances have shed new light on the complexity of sphingolipid metabolism and their various roles in physiology and disease.

    Target of rapamycin (TOR) kinase operates within two distinct multiprotein complexes named TORC1 and TORC2. Here the authors report a cryo-EM structure of TORC2, establish its subunit organization, providing a rationale for TORC2’s rapamycin insensitivity and the mutually exclusive inclusion of Avo3/Rictor or Raptor within their respective TOR complex.
