What is the Meaning of Amino Acid Sequence?

The amino acid sequence represents the precise, linear order in which amino acid residues are linked together to form a polypeptide chain, constituting the primary structure of a protein. This specific arrangement is genetically encoded and dictates the protein's subsequent three-dimensional folding, ultimately determining its biological function. For peptide hormones and receptors, this sequence is the foundational blueprint for their activity and specificity within the endocrine system.

What is the Origin of Amino Acid Sequence?

This fundamental concept is rooted in molecular biology and biochemistry, originating with the elucidation of protein structure in the mid-20th century. The term directly combines "amino acid," the monomer units of proteins, with "sequence," referring to their specific linear arrangement. Understanding the sequence became essential with the rise of genetic code decryption and protein synthesis research.

What is the Mechanism of Amino Acid Sequence?

The sequence is read from the N-terminus to the C-terminus, being transcribed from DNA and translated from messenger RNA (mRNA) via ribosomes. The unique pattern of hydrophobic, hydrophilic, acidic, and basic amino acids drives the folding process into secondary and tertiary structures. This final, intricate conformation is necessary for a hormone or enzyme to correctly bind its receptor or substrate and exert its physiological effect.
