Hydrogen Bonding

A type of weak chemical bond that occurs when a hydrogen atom covalently bonded to a highly electronegative atom, such as oxygen or nitrogen, experiences attraction to another electronegative atom.

Hemoglobin

Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs.

Secondary Structure

The local folded structures that form within a polypeptide due to interactions between atoms in the backbone, typically alpha-helices and beta-sheets.
