All About Proteins

Proteins are vital molecules that constitute a significant part of the cells in all living organisms. They play crucial roles in the body, such as catalyzing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules from one location to another. 🧬✨

Structure of Proteins

Proteins are made up of amino acids, which are the building blocks. These molecules are linked together in polypeptide chains that fold into complex shapes. The sequence of amino acids determines a protein's unique structure and function. 🔬

Functions of Proteins

Enzymatic Activity: Speeding up chemical reactions.
Transport: Moving substances across cell membranes.
Structural Support: Providing support and shape to cells.
Signaling: Communication within and between cells.
