PROTEIN BINDING Meaning and
Definition
-
Protein binding refers to the process by which a drug or other substance attaches or binds to proteins in the body. It is a crucial aspect to consider when understanding how drugs or substances interact with the body and their potential effects.
When a drug is introduced into the body, it can interact with various proteins, such as albumin and globulins, found in blood plasma. These proteins have specific binding sites where the drug molecule can attach. The extent to which a drug binds to proteins can vary depending on factors such as its chemical properties, concentration, and affinity for specific proteins.
Protein binding plays a significant role in determining the drug's distribution and elimination from the body. When a drug is bound to proteins, it is typically in an inactive state and cannot exert its therapeutic effects. Only the unbound, or free, fraction of the drug can interact with its target and cause a pharmacological response. Therefore, if a drug has a high degree of protein binding, it will have fewer free molecules available to produce its desired effect.
Furthermore, protein binding affects the drug's pharmacokinetics, including its absorption, distribution, metabolism, and excretion. Drugs that are highly bound to proteins have a longer half-life, meaning they stay in the body for a longer duration. They may also experience slower metabolism and elimination compared to drugs with lower protein binding.
In summary, protein binding refers to the attachment of a drug or substance to proteins in the body, which can impact its efficacy, distribution, and elimination. Understanding protein binding is crucial in drug development, dosing determination, and predicting potential drug-drug interactions.

Etymology of PROTEIN BINDING
The word "protein binding" does not have a distinct etymology, as it is a compound term made up of two separate words: "protein" and "binding".
"Protein" originated from the French term "protéine", which was coined by the Dutch chemist Gerardus Johannes Mulder in 1839. He derived it from the Greek word "protos", meaning "first" or "most important", reflecting the significant role of proteins in living organisms.
"Binding" comes from the Old English word "bindan", meaning "to tie" or "to fasten". It can be traced back to the Proto-Germanic word "bindanan" and the Proto-Indo-European root "bhendh", carrying a similar meaning.
Therefore, the term "protein binding" essentially refers to the process or action of proteins attaching or bonding to other molecules or entities.
