The recent scientific innovation has resulted in the development of Ultra-Thin Hetero Protein films with remarkable stability across thermal, mechanical, and pH conditions. This innovation could potentially revolutionize the biomedical and food packaging industries. The films comprise two globular proteins: Bovine Serum Albumin (BSA) and Lysozyme (Lys). The Langmuir-Blodgett (LB) technique was leveraged to fabricate these films, ensuring minimal thickness on a nanometer scale. A common type of protein, globular proteins or spheroproteins are spherical and exhibit water-solubility, unlike fibrous or membrane proteins.
Advantages of Ultrathin Heteroprotein Film
Compared to other protein or plastic films, the ultrathin heteroprotein films are thinner, softer, and impart higher flexibility. Recent advancements involve the modification of these protein films using suitable heteroprotein complexes, as reported by different research groups. These complexes are typically developed from bulk solutions.
With BSA and Lys films, there is potential for the creation of highly stable, biodegradable thin films of different protein complexes. This could further expand their use in thin-film technology. Employing various physicochemical methods, such as parameter alteration or incorporation of different fatty acids or polyol moieties (glycerol, starch, gelatin, etc.), the film can be made free standing for a wide range of applications.
An Understanding of Proteins
Proteins are compounds made up of amino acids arranged into various groups. The arrangement of these fundamental amino acid sequences is specific and governed by DNA (Deoxyribonucleic acid). Proteins exist as two primary molecules: fibrous proteins and globular proteins. Fibrous proteins are insoluble and elongated, while globular proteins are soluble and compact.
Function of Proteins
Enzymes: Enzymes primarily facilitate numerous chemical reactions within a cell. They aid in the regeneration and creation of DNA molecules and carry out complex processes.
Hormones: Proteins play a critical role in the production of various hormones that maintain body balance. For instance, hormones such as insulin regulate blood sugar levels, and secretin aids digestion and the formation of digestive juices.
Antibody: Also known as an immunoglobulin, antibodies are proteins employed by the immune system to repair and defend the body against foreign bacteria. They often collaborate with other immune cells to recognize and isolate antigens until white blood cells completely destroy them.
Energy: Proteins serve as a key energy source that facilitates body movement. Consuming the correct amount of protein is essential for it to be converted into energy. When consumed in excess, proteins are converted into fat and become part of fat cells.
