Oxidation vs Reduction- Definition, 8 Major Differences, Examples

Oxidation vs Reduction

Oxidation Definition Oxidation is a chemical process involving the loss of electrons by a molecule, atom, or ion, which increases the oxidation state of the chemical species. The historical definition of oxidation was based on the addition of oxygen to a compound as oxygen gas was the first known oxidizing agent. This definition aligns with … Read more

Enzymes vs Coenzymes- Definition, 8 Major Differences, Examples

Enzymes vs Coenzymes

Enzymes Definition Enzymes are biological molecules that act as biological catalysts and accelerate the rate of chemical reactions in living systems. Enzymes are proteins that act on molecules, known as substrates, in order to produce different molecules called products. Most metabolic processes in biological systems require enzymes so that the processes can occur at rates … Read more

Glucose Definition Figure: Glucose Structure. Glucose is a simple form of sugar that is the primary source of energy in the living systems. Glucose is the most abundant monosaccharide on earth, which occurs and is utilized by different organisms throughout the world. The primary sources of glucose on earth are green plants and algae through … Read more

Deoxyribose vs Ribose Sugar- Definition and 8 Key Differences

Deoxyribose vs Ribose Sugar

Deoxyribose Sugar Definition Deoxyribose is a five-carbon monosaccharide which is the sugar that forms the phosphate backbone of DNA molecules. As the name suggests, deoxyribose is formed by the loss of an oxygen atom from ribose sugar. The molecular formula of deoxyribose sugar is H-(C=O)-(CH2)-(CHOH)3-H, and it might exist in several isomeric forms. The hydroxyl … Read more

Cofactors vs Coenzymes- Definition, 11 Key Differences, Examples

Cofactors vs Coenzymes

Cofactors Definition A cofactor is the non-protein part of an enzyme that is essential for the enzyme’s activity as a catalyst. Cofactors, together with the apoenzyme (protein component), form the complete enzyme (holoenzyme). The removal of the cofactor from an enzyme results in the loss of enzymatic activity. Cofactors can also be termed as helper … Read more

Amylase vs Amylose- Definition and 10 Major Differences

Amylase vs Amylose

Amylase Definition Amylase is an enzyme that catalyzes the hydrolysis of starch to form smaller sugar units by breaking down the glycosidic linkages between glucose units. Amylases are of two types; α-amylase and β-amylase that hydrolyze α- and β-linkages present in the starch molecule, respectively. Besides α- and β-amylases, a third group of amylases called … Read more

Aldoses vs Ketoses- Definition, 7 Major Differences, Examples

Aldoses vs Ketoses

Aldoses Definition An aldose is a monosaccharide consisting of a carbon backbone and a carbonyl group at carbon-1, resulting in an aldehyde group. The general formula of aldoses is the same as most carbohydrates, Cn(H2O)n. The carbon atoms in the carbon backbone are each bonded to a hydroxyl group. All aldoses exhibit stereoisomerism as they … Read more

Amylose vs Amylopectin- Definition and 12 Major Differences

Amylose vs Amylopectin

Amylose Definition Amylose is a polysaccharide consisting of α-D-glucose units that are linked together by α(1→4) glycosidic bonds. An amylose is an essential form of resistant starch that is more resistant to digestion than other starch molecules.  The tightly packed helical structure of the molecule aids in its resistance. The carbon atoms in glucose are … Read more
