Science Words that start with Z

Science Words and its Definitions in Chemistry

Zaitsev’s Rule: Zaitsev’s rule refers to the empirical rule that predicts the highly substituted alkene compound is removed from a chemical and elimination reaction. It is a significant rule in all elimination reactions in organic chemistry.

For Example, The highly substituted compound in the reaction between 2-iodobutane and alcoholic potassium hydroxide (KOH) is 2-butene. Here, 2-butene is the most stable and favored compound eliminating in the reaction.

Zeolites: Zeolites are the microporous crystalline rock-hard materials that come with a framework of hollow cavities. These complex substances encompassed aluminium, oxygen, and silicon, allowing water and other small molecules to fit in hollow channels. And the hollow cavities and canals refer to molecular sieves.

In chemistry, zeolites help separate molecules and work as a trap to hold specific molecules. Besides, zeolites come in use for purifying and softening the water through the ion-exchange method.

Zeeman Effect: In physics and astronomy, Zeeman Effect is the effect that explains the splitting of spectral lines using static magnetic fields into at least one or more than two components. And these components vary slightly in frequencies while the light source comes in contact with a magnetic field. However, this effect resembles the Stark Effect, which also explains the spectral line is splitting but in the electric field.

Z (Zusammen): Z denotes substituent groups’ arrangement from higher to lower places according to their stereochemical arrangements. These stereochemical arrangements are mostly happening in alkene double bonds.

Zepto: Zepto refers to the unit in metric system used as a prefix for substances associated with x10-21, i.e., 0.000000000000000000001. As it is equal to 1000⁻⁷, it came from the Latin word ‘Septem,’ which means seven. For Ex: The electric charge on one electron: 160.217657 zepto-coulombs.   

Zetta: Zetta is again another unit prefix in the metric system, but it denotes the decimal units and adds as a prefix for substances with x1021. Z represents the unit prefix Zetta.

Zeta Potential (ζ-potential): The scientific term used for abbreviating electro-kinetic potential in the colloidal systems at the slipping planes is zeta potential. To put it simple, the possible dissimilarity between two different states of matter, i.e., solids and liquids across their boundaries, is zeta potential.

For suppose, if a colloidal substance is more stable means, it consists of higher zeta potential. While a zeta potential value is zero, then the colloidal substance remains a residue in solid form.

Zero Order Reaction: The reactions whose reaction rate does not depend on reactants’ concentration are zero-order reactions.

For Ex: The photochemical reaction between chlorine and hydrogen, Decomposition of NH3 in the presence of molybdenum or tungsten, Iodization of acetone in H+ ions are a few best examples of zero-order reactions.

Ziegler-Natta Catalyst: Ziegler-Natta catalyst, the catalyst named after Karl Ziegler and Giulio Natta, and is useful for the synthesis of α-olefin polymers and 1-alkene. Primarily, the polymers synthesized through this catalyst constitute highly molecular weights and stereo-regular structures.

Zero-Point Energy: Zero-point energy, also known as a ground state, represents the level possessing the lowest potential energy in a quantum mechanics system.

Zinc: In chemistry, zinc is a brittle chemical element that appears bluish and silvery in color with atomic number 30 and symbol ‘Zn.’ In the human body, zinc is the second most significant mineral that is useful in many ways to perform bodily functions. It also plays a vital role in performing many functions of the human body, such as nerve function, digestion, metabolism, etc. On the other hand, it also helps the human body’s immune system invade viruses and bacteria.

Zirconium: Zirconium, a strong transition metal cum chemical element holding the atomic number 40 and symbol ‘Zr.’ By appearance, it is silverfish grey and malleable, strong, and ductile by nature. And hence, it is highly resistant to corrosion and used in corrosive environments. 

Zincography: The planographic or lithographic process of attaining zinc plates to produce a printing surface using a strong acid is called zincography.

 Zone Refining: The chemical processing of purifying crystalline substances like metals and other semi-conductors is zone refining. This process happens by creating a narrow molten zone to make impurities concentrated and travel alongside. Floating zone process, zone melting, and travelling melting zone are other names for zone refining.

Zwitterion: Any chemical molecule or ion which consists of an isolated and equal number of positive and negative charged functional groups is a zwitterion. Amino acids are the best examples of zwitterions with functional groups, amines, and a group of carboxyls.

Zymase: The enzyme which catalyzes the fermentation reaction in alcohols to breakdown certain sugars is zymase. It is a combination of enzymes resulting from the fermentation of yeast. For Ex: breaking sugars into ethanol and carbon dioxide. Though it occurs in all kinds of the yeast strain, the reaction varies from one strain to another. The name zymase also refers to the drug pancrelipase.

Zymogen: Inactive protein, also called a proenzyme, undergoes biochemical reactions to synthesize enzymes along with an organism is zymogen. This biochemical process generally happens in Golgi bodies, where the isolated enzyme is divided into specific parts to activate the inactive proteins. For Ex: Pepsinogen is the precursor of pepsin.

Zymurgy: The scientific research and study on fermentation (biochemical process) happening especially while brewing, distilling, and winemaking is Zymurgy. The scientist who works on conducting the research studies on the fermentation process while brewing and winemaking is a zymurgist. And zymology is the branch of applied science that tells about the biochemical process of fermentation and its uses in brewing and distilling is zymology.

Zero: Zero is simply a number that represents neutral value in mathematics and helps us understand the integers, algebraic structures, and real numbers. When zero is placed on the left side of a number, it does not add any value to that, but it adds value to that number when placed on the right side of a number.

Z-Axis: Z-Axis is the third co-ordinate axis in a three-dimensional space and is generally oriented vertically.

Z-DNA: DNA in living organisms comes in many possible ways in double-helical structures and hence divides the parent sequence into many types of DNA. Among them, Z-DNA is one type of DNA with left-handed double-helical structures. This means the helix takes a turn on the left-handed side and shows a different pattern because of an alternate pattern of bases in syn and anti-conformation.
