amino acid sequence

An amino acid sequence is a specific arrangement of amino acids, which are the building blocks of proteins. Proteins are essential molecules that perform a vast range of functions in living organisms, including support, transport, and catalysis. The order of amino acids in a sequence determines a protein's structure and function. Think of it like a sentence where each word (amino acid) has a unique role, and the overall meaning (function) depends on how the words are organized. Changes in this sequence can affect how a protein works, which can influence health and biological processes.
