Proteins

Definition

Proteins are large, complex molecules made up of amino acids, which play critical roles in virtually every biological process within living organisms. They are essential for the structure, function, and regulation of the body’s tissues and organs, influencing a variety of functions from enzymatic reactions to immune responses. In the context of synthetic virology and genome engineering, proteins can be engineered or synthesized to create viral vectors, modify viral genomes, or produce therapeutic agents that target specific diseases.

5 Must Know Facts For Your Next Test

1. Proteins are made up of 20 different amino acids that can be arranged in countless combinations to form a wide variety of protein structures.
