Molecular binding is an attractive interaction between two molecules that results in a stable association in which the molecules are in close proximity to each other. It is formed when atoms or molecules bind together by sharing of electrons.
Paper bonds as an option for receiving an individual's federal income tax refund will be discontinued January 1, 2025. [11] The paper bonds were issued in denominations of $50, $100, $200, $500, and $1,000, featuring portraits of Helen Keller, Martin Luther King Jr., Chief Joseph, George C.

For some bonds, such as in the case of TIPS, the underlying principal of the bond changes, which results in a higher interest payment when multiplied by the same rate. For example, if the annual coupon of the bond were ...

The first description of cooperative binding to a multi-site protein was developed by A.V. Hill. [4] Drawing on observations of oxygen binding to hemoglobin and the idea that cooperativity arose from the aggregation of hemoglobin molecules, each one binding one oxygen molecule, Hill suggested a phenomenological equation that has since been named after him:
