Lewis antigens are synthesized primarily by endodermal epithelia, such as GI epithelia, but are found in endodermal epithelia and RBCs due to transfer of glycolipids to RBCs (Henry et al., 1995).Lewis structuresare found on type 1 and 2 chains of O-glycans, N-glycans, and glycolipids. ...
Lewis Structures and Molecular Shapes Honors Chemistry Lab Objectives The objectives of this laboratory are: a) To practice drawing Lewis Structures for various covalently bonded molecules and polyatomic ions. b) To use model kits to construct these molecules/ions in order to explore their structure ...

Polarity of covalent bond:The bond pair is equally shared in between two atoms when the electronegativity difference between them is zero or nearer to zero. In this case, neither of the atoms gets excess of electron density and hence carrynocharge. This is callednon polar covalent bond. ...
