Atoms and Molecules
Everything in the universe is made up of matter, and matter is composed of a combination of elements. An atom is the smallest unit of an element that retains all properties of the element. For example, a silver coin is made up of silver atoms, and each silver atom retains the unique properties of the element — silver.
Elements are pure substances consisting of identical atoms that cannot be broken down into simpler substances by chemical changes. Atomic...
All living things are formed mostly of carbon compounds called organic compounds. The category of organic compounds includes both natural and synthetic compounds that contain carbon. Although a single, precise definition has yet to be identified by the chemistry community, most agree that a defining trait of organic molecules is the presence of carbon as the principal element, bonded to hydrogen and other carbon atoms. However, some carbon-containing compounds such as carbonates, cyanides, and...
Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond.
Elements
Elements are classified as atomic or molecular based on the nature of their basic units. They are unique forms of matter with specific chemical and physical properties that cannot break down into smaller substances by ordinary chemical reactions. There...
Overview
The ability of a single antibody to recognize multiple structurally similar epitopes is an important immune defense strategy that enables the host to efficiently defend against many potentially threatening pathogens. However, cross-reactivity also elicits allergy symptoms against related allergens. It is increasingly important to understand the principles of cross-reactivity, as antibodies are actively being developed as therapeutic modalities for diverse diseases, including cancer.
Enols are a class of compounds where a hydroxyl group is attached to a carbon–carbon double bond, which implies that it is a vinyl alcohol. A carbonyl compound with an α hydrogen undergoes keto–enol tautomerism and remains in equilibrium with its tautomer, the enol form. Usually, the keto tautomer is present in a higher concentration than the enol tautomer due to the higher bond energy of C=O compared to C=C. Moreover, the direction of the keto–enol equilibrium is...
Solubility is the measure of the maximum amount of solute that can be dissolved in a given quantity of solvent at a given temperature and pressure. Solubility is usually measured in molarity (M) or moles per liter (mol/L). A compound is termed soluble if it dissolves in water.
When soluble salts dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution; this process represents a physical change known as dissociation. Potassium chloride (KCl) is an example...
