Today we take a brief look at proteins. Proteins are made up amino acids. Amino acids (AA) are small chemicals. Humans can produce some AAs, whereas others have to be salvaged from our food. Those AAs are mostly synthesized by bacteria. Proteins have many purposes and roles. They make up a large portion of our body's dry mass. Proteins can for example catalyze chemical reactions, those proteins are called enzymes. Proteins are also vital in our structural integrity, such as the widely known collagen. Then there are proteins which transport other molecules or facilitate the diffusion of proteins in and out of cells and cell organelles. Up to this point proteins are also our main focus in medicinal research. Not that they are the only research target, but they are the most accessible. There is plenty of structural and operational information available. This is also due to ease of access and researchability. Thus most of our medications (excluding antiinfectives) target proteins. Proteins are predictably also playing a key role in many diseases. For example in Alzheimer's disease and Parkinson's disease. Both cases can at least partially be attributed to accumulation of wrongly produced proteins, commonly called plaques. Today was a little more broad. I could go into details of so much here that I tried to give some general knowledge. Hope you have a delightful day and stay healthy đ
