Proteiinijäägid, sometimes referred to as protein residues, are the individual amino acid units that make up a protein molecule. Proteins are polymers, meaning they are long chains of smaller repeating units. These smaller units are amino acids, and when they are linked together in a specific sequence, they form a polypeptide chain, which then folds into a functional protein. Each amino acid within the chain retains its distinct chemical properties, contributing to the overall structure and function of the protein.

The sequence of these amino acid residues, known as the primary structure, is determined by genetic information. Variations in this sequence can lead to different proteins with unique characteristics. The way these residues interact with each other, forming secondary structures like alpha-helices and beta-sheets, and then further folding into a three-dimensional tertiary structure, is crucial for protein function. Even further complexities can arise with quaternary structures, where multiple polypeptide chains (each composed of protein residues) assemble. Understanding the properties and interactions of these protein residues is fundamental to comprehending protein biology, including how proteins fold, interact with other molecules, and perform their diverse roles in living organisms.
