Thermodynamics: A Relationships Between Heat and Other Forms of Energy (Part 2)

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. …

Thermodynamics: A Relationships Between Heat and Other Forms of Energy (Part 1)

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: The Central to Nutrition

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 …

Bacterial Structure

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 …

Protein and Peptides: An Inevitable Source of Nutrition (Part 1)

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 …

Lipids and Fatty Acids: An Inescapable Organic Compounds

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. …
