The primary structure of a protein refers to its unique sequence of amino acids, which determines its overall shape and function. This linear sequence is held together by peptide bonds and is crucial for the protein's biological activity and interactions.

A function is a fundamental concept in mathematics and computer science that describes a relationship or mapping between a set of inputs and a set of possible outputs, where each input is related to exactly one output. Functions are used to model real-world phenomena, perform calculations, and define operations in programming languages, making them an essential tool for problem-solving and analysis.

A linear sequence is an ordered list of numbers where each term after the first is generated by adding a constant difference to the previous term. This simple yet powerful structure is foundational in mathematics, serving as a basis for understanding more complex patterns and relationships.

Peptide bonds are covalent chemical bonds that link amino acids together in a polypeptide chain, forming the primary structure of proteins. They are formed through a dehydration synthesis reaction between the carboxyl group of one amino acid and the amino group of another, resulting in the release of a water molecule.

Biological activity refers to the effect a substance has on living organisms, tissues, or cells, and is a critical measure in pharmacology and toxicology for assessing the efficacy and safety of drugs and chemicals. It encompasses a wide range of interactions, including enzyme inhibition, receptor binding, and gene expression modulation, which are crucial for understanding the mechanism of action of bioactive compounds.
