Globular and fibrous proteins A protein whose molecules curl up into a ‘ball’ shape, such as myoglobin or hemoglobin, is known as a globular protein. In a living organism, proteins may be found in cells and in other aqueous environments such as blood, tissue fluid and in phloem of plants. …

Units of work Whenever a new quantity is introduced in physics, the standard metric units associated with that quantity are discussed. In the case of work (and also energy), the standard metric unit is the Joule (abbreviated J). One Joule is equivalent to one Newton of force causing a displacement of one meter. …

The study of the flow of warmth or the other sort of energy into or out of a system because it undergoes a physical or chemical transformation, is named Thermodynamics. In other word relationship between heat, work, temperature, and energy. In broad terms, thermodynamics deals with the transfer of energy from one place to a different and from one form to a …

Carbohydrates are fundamentally the sugars, starches and fibers found in fruits, grains, vegetables and milk products. Though often it slander in trendy diets, carbohydrates which is one of the basic food groups which are important to a healthy diet. A carbohydrate is a biomolecule containing of carbon (C), hydrogen (H) and oxygen (O) atoms, normally with …

Bacteria (singular: bacterium) are microscopic unicellular organisms that thrive in a variety of environments. These organisms can live in the soil, in the ocean and in the human gut. This organisms are available almost everywhere on our earth and are important to the planet’s ecosystems. Some species can live under …

Bacteria (singular: bacterium) are classified as prokaryotes. They are single-celled life/body with a simple core-less internal structure and contain DNA that swims freely in a twisted, thread-like matter called a nucleoid, or in circular parts called plasmids. Bacteria are single-celled microscopic life/organisms that grow in different environments, and these organisms can live in …

Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells, and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which …

In biology and biochemistry, a lipid is a macro-biomolecule that is soluble in nonpolar solvents. Non-polar solvents are typically hydrocarbons used to dissolve other naturally occurring hydrocarbon lipid molecules that do not (or do not easily) dissolve in water, including fatty acids, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, triglycerides, and phospholipids. …

Proteins are an extremely important class of macromolecule in living organisms. More than 50% of the dry mass of most cells is protein. Proteins have many important functions. Amino Acids are the building units of proteins. Proteins are polymers of amino acids linked together by what is called “Peptide bond”. …

The polymerase chain reaction, generally known as PCR, is used in almost every application of gene technology. It is a method for rapid production of a very large number of copies of a particular fragment of DNA. Virtually unlimited quantities of a length of DNA can be produced from the …
