Document Summary
Protein: string of amino acids, polypeptide chain, polymer of smaller molecules. Mechanism for relaying info from the outside of the cell to the inside of the cell, initiating changes in the cell behavior. Modifiers that change the function of other proteins, turning proteins on and off. Signals produced by the cells, and also the receptors that receive those signals and the components of the transduction pathways that interpret those signals. Important for the unique identity and function of membrane-bound organelles in the cell. Virtually unlimited molecular structures that proteins can assume. Each protein has its own unique, defined structure that allow it to carry out a particular function. Structure is essential for defining the substrate binding domain and the activity domain. Even after a polypeptide is formed, post-translational modifications can alter the properties of individual amino acids and the whole protein. Central carbon has four functional groups (bonds)* check on module vid.
