• The phosphonium (more obscurely: phosphinium) cation describes polyatomic cations with the chemical formula PR+4 (R = H, alkyl, aryl, halide). They are tetrahedral and generally colorless.
• It is helpful if you: Try to draw the PO 3 3-Lewis structure before watching the video.; Watch the video and see if you missed any steps or information. Try structures similar to PO 3 3-for more practice. The REDantibody based on the X-ray crystallographic structures of the anti-sialyl-Tn antibody B72.3 and 3D model of the monomeric red fluorescent protein was designed to retain optimal spatial geometry between the C- and N- termini of the V H and V L chains respectively to mimic the domains interface pairing in antibody Fab fragments and to ...
