Protein folding has nothing to do with laundry. It is, in fact, one of the central questions in biochemistry. Protein folding is the continual and universal process whereby the long, coiled strings of amino acids that make up proteins in all living things fold into more complex three-dimensional structures. By understanding how proteins fold, and what structures they are likely …

Proteins are very important in biological systems as control and structural elements. Control functions of proteins are carried out by enzymes and proteinaceous hormones. Enzymes are chemicals that act as organic catalysts (a catalyst is a chemical that promotes but is not changed by a chemical reaction). What are Proteins? The building block of any protein is the amino acid, …

Lipids are involved mainly with long-term energy storage. They are generally insoluble in polar substances such as water. Secondary functions of lipids include structural components (as in the case of phospholipids that are the major building block in cell membranes) and “messengers” (hormones) that play roles in communications within and between cells. Lipids Definition: Lipids are a group of naturally occurring molecules …

What are the components of nucleic acids? Before going to discuss this, you should know the basics of Nucleic acids and their components. Nucleic acids are organic polymers, composed of monomer units known as nucleotides. Nucleotides are energy-rich compounds that drive metabolic processes in all cells. They also serve as chemical signals, key links in cellular systems that respond to …

In this article, we are adding Amino acids Classification details. Amino acids are the building blocks of the molecular structure of the important and complex class of a compound known as Proteins. The proteins on hydrolysis yield mixtures of the component amino acids. Therefore, to understand the structure and chemistry of proteins, we have to first undertake the study of …

What is Amino acid? Amino acids are monomeric units of proteins. Proteins are high molecular weight organic polymer. Although about 200 to 300 amino acids occur in nature, only 20 of them are seen in human body. What is Amino Acid ? Before going to discuss what is amino acids, we want to discuss few points on the historical points. …

Are you searching for the protocol on Color reactions of Lipids? Lipids are one of the major constituents of foods and are important in our diet for a number of reasons. They are a major source of energy and provide essential lipid nutrients. Nevertheless, over-consumption of certain lipid components can be detrimental to our health, e.g. cholesterol and saturated fats. …

Monosaccharides are the simplest carbohydrates in that they cannot be hydrolyzed to smaller carbohydrates. They are basic units of Carbohydrates. They are made up of only one carbohydrate moiety. The general chemical formula of an unmodified monosaccharide is (C•H2O) n, literally a “carbon hydrate”. This is termed as the empirical formula. In this formula, the “n” varies from 3-6 and …
