多肽和蛋白质的氨基酸是一个简单的摩尔cule formed with C, H, O, N and may be S. It has the following general structure. There are about 20 common amino acids. All the amino acids have a –COOH, -NH2 groups and a –H bonded to a carbon. The carbon is a chiral […]
Difference Between Oxidation Reaction and Reduction Reaction
Oxidation Reaction vs Reduction Reaction Oxidation and reduction reactions are interrelated. Where one substance is oxidized another substance reduces. Therefore, these reactions are jointly known as redox reactions. Oxidation Reaction Originally oxidation reactions were identified as the reactions wherein oxygen gas participates. Here, oxygen combines with another molecule to produce an oxide. In this […]
Difference Between Hydrogen Bond and Covalent Bond
Hydrogen Bond vs Covalent Bond Chemical bonds hold atoms and molecules together. Bonds are important in determining the chemical and physical behavior of molecules and atoms. As proposed by the American chemist G.N.Lewis, atoms are stable when they contain eight electrons in their valence shell. Most of the atoms have less than eight electrons […]
Difference Between Isotopes and Isobars
Isotopes vs Isobars Atoms are the small building blocks of all existing substances. There are variations between different atoms. Also, there are variations within the same elements. Isotopes are examples for differences within a single element. Isobars are different elements with a similarity. Isotopes Atoms of the same element can be different. These different […]
Difference Between Bromine and Bromide
The key difference between bromine and bromide is that bromide is the reduced form of bromine. The chemical elements in the periodic table are not stable except for the noble gases. Therefore, elements try to react with other elements to gain the noble gas electron configuration to achieve stability. Likewise, bromine also has to get […]
Difference Between Bromine and Chlorine
The key difference between bromine and chlorine is that Bromine is less reactive than chlorine. Halogens are group VII elements in the periodic table. All of these elements are electronegative elements and have the capability to produce -1 anion. The members of this group include fluorine, chlorine, bromine, iodine and astatine. CONTENTS 1. Overview and Key […]
Difference Between Carbon Steel and Mild Steel
Carbon Steel vs Mild Steel Steel is an alloy made out of iron and carbon. The carbon percentage can vary depending on the grade and mostly it is between 0.2% and 2.1% by weight. Though carbon is the main alloying material for iron some other elements like Tungsten, chromium, manganese can also be used […]
Difference Between Cysteine and cystine
The key difference between cysteine and cystine is that cysteine is an amino acid while cystine forms when two amino acids join together via a disulfide bond. An amino acid is a simple molecule formed with C, H, O, N and maybe S. There are about 20 common amino acids. All amino acids have a […]
Difference Between Cellulose and Cellulase
Cellulose vs Cellulase When ten or higher number of monosaccharides is joined by glycosidic bonds, they are known as polysaccharides. They are also known as glycans. There chemical formula is Cx(H2O)y. Polysaccharides are polymers and, therefore, have a larger molecular weight, typically more than 10000. Monosaccharide is the monomer of this polymer. There can […]
Difference Between Saturated and Unsaturated Hydrocarbons
饱和与不饱和Hydrocarbons Organic molecules are molecules consist of carbons. Organic molecules are the most abundant molecule in living things on this planet. Main organic molecules in living things include carbohydrates, proteins, lipids and nucleic acids. Nucleic acids like DNA contain genetic information of organisms. Carbon compounds like proteins make structural components of […]
