Have you ever thought to yourself: What is Life? Though that’s a question that has circulated throughout internet culture these days, the answer you’re looking for may lie in the science of proteins. Proteins are one the major components of what makes us who we are. In other words, they hold the answers to the questions we may have about life. Proteins, our worker molecules, are necessary for pretty much every activity in our bodies. They circulate in our blood, seep from our tissues, and grow . Proteins are also the key components of biological materials ranging from silk fibers to elk antlers.Proteins are essential to the function of our bodies. They help with muscle strength, they preside in our hair and nails. Your body uses protein to build and repair tissues. You also use protein to make enzymes, hormones, and other body chemicals. Protein is an important building block of bones, muscles, cartilage, skin, and blood. It’s in our food, a foundation for fitness.Proteins are all around us.What Are Proteins Made Of?Amino acids, the building blocks of proteins, are small organic molecules. They are comprised of a central carbon atom that’s linked to a carboxyl group, an amino group, a hydrogen atom, and a variable component called a side chain (source). Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. When a water molecule is extracted during a biochemical reaction, the water molecule joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid (source). This is how peptide bonds are formed. The linear sequence of amino acids within a protein is considered the primary structure of the protein (source).Proteins are built from a set of twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries. The largest group of amino acids have nonpolar side chains. Several other amino acids have side chains with positive or negative charges, while others have polar but uncharged side chains.ProteomicsProteins are the functional units of life. Together they orchestrate most biological functions required for any cell, organ or organism to function. Our understanding of biological systems relies on the ability to directly quantify proteins on a proteome-wide scale.Proteomics aims at understanding the proteome by enabling the unbiased and large-scale study of proteins. At Biognosys, we focus on the field of proteomic research. Proteomics is the long-term study of proteins and we have dedicated our time to decoding the proteome in order to leave a great impact on our understanding of biological processes that shape life.
