Some chemical terminology explained

Activation energy: the minimum energy that reactant particles must possess during their collisions in order to a chemical reaction occur.

Alkali: a substance that dissociates in water to produce hydroxide ions ( -OH )

Bases that are soluble in water are known as alkali.

Alcohol: an organic compound containing the hydroxide group ( -OH )

Carboxylic acid: an organic acid containing the carboxyl group ( -COOH )

End point: the point in a titration at which in an indicator changes color.

Ester: an organic compound formed from the reaction of an alcohol and a carboxylic acid.

Functional group: an atom or group of atoms that give characteristic properties to an organic compound.

Isomers: compounds that have the same molecular formula but different structural formulae.

Organic chemistry: chemistry that deals with carbon-based compound.

Protein: a natural polymer of amino acids.

Aldehyde: an organic molecule containing a -COH group.

Amine: an organic molecule, which consists of ammonia molecule, where one or more of the hydrogen atoms have been replaced by organic groups.

Buffer: a liquid that resists the change of pH by the addition of acid or base.

Addition reaction: a reaction where atoms add to a carbon-carbon multiple bond.

Tears as a remedy for the skin

Tears as a remedy for the skin Expressing spontaneous emotions, particularly the negative ones, considered a sign of immature or inability to self-control, but crying, in fact, is a sign of emotional intelligence, which allows realizing one’s feelings and expresses them appropriately.

They are rich in antibacterial protein, which keeps the eyes moisturize each time you blink, helping in improves one’s vision. Existing constantly in the eyes; thus, they prevent dryness of tunica mucosa . Aging decreases the secretion of this type of tears. Newbo...

Chemistry of cleaning materials

Chemistry of cleaning materials Chemistry keeps you clean, in which cleaning products are formulated with different chemical properties. The main reason behind inventing the soap was cleaning dishes and using it in medicine, as Galen mentioned. Babylonians around 2800 BC were the first, who manufactured soap-like materials, using plants and animal fats boiled with ashes and water. Whereas, the ancient Egyptians in 1550 BC made a product similar to soap through mixing animal and vegetable oils with alkaline salts, and women used it for washing their hairs. Also, in 600 BC the Phoenicians mixed goat fat with wood ash; Syrians and Palestinians were the first, who used olive oil, laurel oil, and thyme oil and potash. However, modern cleaning products vary, for example soap, detergent, air freshener, and bathroom polish, containing a number of chemicals. Soap includes sodium salts of long-chain carboxylic acids obtained by natural resources from plants and anima...

Vaccines

Vaccines A vaccine is a biological preparation of weakened, killed, or fragmented microorganisms, or toxins, antibodies, or lymphocytes that introduce into the body to produce immunity to a specific disease. Vaccination is a method, which prevents disease occurrence instead of treats it. Vaccines vary into different types, including live-attenuated , inactivated , toxoid , and conjugate as well as recombinant vaccines. Administration of a vaccine is an important factor in order to ensure transporting it to the proper part of the body; therefore, transport of a vaccine has several mechanisms. For example, intramuscular , subcutaneous , or intradermal injection, and oral administration in addition to intranasal spray are applications that delivers vaccine. Live-attenuated vaccines Live-attenuated vaccines contain whole bacteria or viruses, but these are weakened and do not cause illness in a healthy individual, however, immune system patients are not ...
