One-letter and three-letter codes for amino acids

What is one- and three-letter codes for amino acids? Amino acids are the building blocks of proteins, and the specific sequence of amino acids determines the function and structure of the protein. To represent the 20 different amino acids, a system of codes has been established, with two commonly used formats: one-letter and three-letter codes. … Read more

Actinometry

What is actinometry? Light is a fundamental and ubiquitous form of energy in our world, and it plays a crucial role in many scientific fields, including chemistry, physics, and biology. However, measuring the intensity of light and its impact on chemical reactions can be challenging. This is where actinometry comes in.. Actinometry is a technique … Read more

List of acronyms and abbreviations for chemical compounds

What is acronyms and abbreviations for chemical compounds? In chemistry, acronyms can be found in various contexts such as chemical formulas (compounds), laboratory techniques, and scientific instruments, etc. Acronyms in chemistry serve as shorthand notations for commonly used terms, which can make it easier for scientists to communicate quickly and efficiently. For example, BBN stands for … Read more

Melting point of the elements

Melting point is defined as the temperature at which a chemical element changes from the solid to the liquid phase at a pressure of one atmosphere. In the International System of Units (SI) it is measured in K (Kelvin). To convert to ºC (degrees Celsius) the following expression is used: Temperature (K) = Temperature (ºC) … Read more

E numbers Table

Food additives are assigned a code in the EU called “E-numbers” (the E for Europe). These are codes for substances used as food additives for use within the EU and the European Free Trade Association (EFTA). Commonly found on food labels, their evaluation and safety approval is the responsibility of the European Food Safety Authority … Read more

Lewis acid-base theory

What is the Lewis acid-base theory? In 1923, Lewis proposed a theory to explain the behavior of acidic and basic substances. This is because previous theories, such as Brønsted-Löwry, defined them in terms of proton acceptance/transfer (H⊕). However, substances were known which, lacking hydrogen in their molecule, such as SO3 and CO2, behave as acids. … Read more

Hydrolysis

What is hydrolysis? Literally hydrolysis means breakage by water. We know that when an acid and a base react with each other a salt plus water is formed: AH +BOH <–> AB + H2O It is conceivable that if the process is reversible, i.e., that when a salt dissolves in water, an acid or base may appear … Read more

Bond polarity

What is bond polarity? Bond polarity can be defined as the difference in electronegativity (δEN) between the two bonding atoms. The greater the difference in electronegativity, the more polar the bond. Types of bonds If a bond is formed by two equal atoms (same electronegativity) it gives rise to a covalent bond, they share electrons … Read more

Arrhenius acid-base theory

What is the Arrhenius acid-base theory? Acids: substances that in aqueous solution dissociate by yielding protons (H+). Acids: sustancias que en disolución acuosa se disocian cediendo protones (H+). Bases: substances that in aqueous solution dissociate by yielding hydroxide ions (OH–). Salts: substances that in aqueous solution dissociate by yielding other ions. In general the dissociation equations are: … Read more
