Study Notes
- Proteins are biological molecules composed of amino acids linked together, with 20 different amino acids used in the human body to build proteins.
- Proteins serve various functions in the body, including structural support (e.g., cytoskeleton, collagen), enzymatic activity, transportation of molecules, immune function (e.g., antibodies), and cell signaling.
- Protein structure involves primary structure (sequence of amino acids), secondary structure (local three-dimensional changes due to hydrogen bonds), tertiary structure (overall 3D shape stabilized by interactions like hydrogen bonds and disulfide bonds), and quaternary structure (interaction of multiple polypeptide chains).
- The specific 3D shape of a protein is crucial for its function as it determines its ability to bind to other molecules (ligands) in a lock-and-key manner.
- Denaturation of proteins occurs when they lose their 3D structure due to disruptions in weaker interactions like ionic bonds, hydrogen bonds, and hydrophobic interactions, often caused by factors like extreme heat, pH levels, or salt concentrations.
- Denaturation can be observed in everyday scenarios like frying an egg, where the clear egg white denatures and turns opaque due to heat-induced protein structural changes.
- Proper body temperature, salt concentrations, and pH levels are essential for maintaining protein structure and function, as denaturation can lead to the loss of protein function.
