Protein structure, molecular model - 4K stock video

Molecular model of a protein, showing its atoms and bonds as a ball and stick model, along with a curve highlighting its secondary and tertiary structure. Primary protein structure is the sequence of amino acids that make up the protein. The order of these proteins determines the secondary structures, which include alpha helices (coils) and beta sheets. These secondary structures combine to form the tertiary structure of the protein. The overall shape of the protein is critical to its function
