The course begins with the genesis of biological chemistry, which is a field of study that combines biology and drug discovery processes. You will learn about the biological system from a molecular perspective. This field of study started when American chemist Linus Pauling determined the structure of proteins, which are biological molecules. Gain insight into the intersection of chemistry and biology to appraise the evolving field of study of biological molecules. These are also called ‘the molecules of life’; they are present in all living systems and consist broadly of proteins, nucleic acids, lipids and carbohydrates. This course will describe the structure of the macromolecules that make up the biological system and show that, without them, the living system cannot survive. You will also learn about the building blocks of protein - amino acids - and get introduced to monosaccharides and nucleotides or deoxynucleotides, which are the building blocks of carbohydrates and nucleic acids, respectively.
Living systems consist of organs, which are made of tissues that are comprised of cells. Each biological cell will have the molecules of life and you will study their structure, importance and functions. Grapple with the central dogma of biology, which is about how information flows from the nucleic acids to the proteins, to understand the relationship between the molecules of life. You will learn the structure of glucose, which is a basic carbohydrate, and why lipids are different from the other three molecules of life. Neutral lipids, such as fatty acids, certain steroids or terpene, are not soluble in water. You will understand the structure of different types of lipids and you will also be introduced to the polymers of nucleotides, or the nucleic acids, which are the genetic materials of all eukaryotic cells. Biological systems are formed of large molecules (or macromolecules) and small molecules. Macromolecules are proteins, carbohydrates and nucleic acids. You will also gain an understanding of the structure and importance of certain small molecules like neurotransmitters, vitamins, dopamine and acetylcholine.
Next, you will get an in-depth understanding of amino acids, their structure, isoelectric point, zwitterions (or inner salts) and chirality. Isoelectric point is the pH at which the intermediate ion or zwitterion has an overall neutral charge. You will learn to calculate the isoelectric point, if the pH values are given. Master the concept of ‘chirality’ and the stereochemistry of amino acids and, lastly, you get brief insight into the separation of amino acids and peptide bond synthesis. Chemists need to know the basics of biology to understand the nature and type of chemistry that goes on in the biological system. Biologists, too, have to study the biological system from the standpoint of molecules, to analyze the precise microscopic details of any process of synthesis or decomposition. If you are a chemistry or biology enthusiast or from the pharmaceutical industry, you can benefit from this course and chart a new path of success in your professional development.Start Course Now
