The key difference between contraction and constriction is that contraction is the reduction of size or shortening of muscles, while constriction is the act of tightening, narrowing or closure. Contraction and constriction are two types of processes taking place in muscles. Contraction takes places in skeletal muscles. Constriction takes place in smooth muscles. Both are […]
Difference Between MDI and TDI
The key difference between MDI and TDI is that MDI occurs as a light yellow crystalline solid, whereas TDI occurs as a clear, colourless to pale yellow colour liquid. MDI and TDI are two different forms of diisocyanates. These are useful in polyurethane production. There are two major types of diisocyanates as aromatic diisocyanates and […]
Difference Between Serine and Tyrosine Recombinase
The key difference between serine and tyrosine recombinase is that in serine recombinase, serine is the nucleophilic amino acid used by the enzyme to attack DNA during site-specific recombination, while in tyrosine recombinase, tyrosine is the nucleophilic amino acid used by the enzyme to attack the DNA during site-specific recombination. Site-specific recombination (conservative site-specific recombination) […]
Difference Between Proliferative and Nonproliferative Retinopathy
The key difference between proliferative and nonproliferative retinopathy is that proliferative retinopathy refers to the presence of neovascularization (abnormal blood vessel growth) in the retina in diabetic retinopathy, while nonproliferative diabetic retinopathy refers to early diabetic retinopathy disease without neovascularisation. The later stages of diabetic retinopathy are known as proliferative diabetic retinopathy (PDR). In this […]
Difference Between Detrital and Grazing Food Chain
The key difference between detrital and grazing food chain is that detrital food chain is a food chain that begins with dead organic matter as the main source of energy while grazing food chain is a food chain that begins with green plants as the main source of energy. A food chain illustrates the feeding […]
Difference Between ABO and Rh Blood Grouping System
The key difference between ABO and Rh blood grouping system is that ABO blood grouping system is based on the presence or absence of the antigens A and B on the surface of the red blood cells, while Rh blood grouping system is based on the presence or absence of the Rh antigen (Rh factor) […]
Difference Between Cetyl Alcohol and Cetearyl Alcohol
The key difference between cetyl alcohol and cetearyl alcohol is that cetyl alcohol is a single chemical compound, whereas cetearyl alcohol is a mixture of chemical compounds. Cetyl alcohol and cetearyl alcohol have different chemical and physical properties and different applications. Cetyl alcohol is a type of fatty alcohol having the chemical formula CH3(CH2)15OH while cetearyl […]
Difference Between Phosphodiester Bond and Phosphoester Bond
The key difference between phosphodiester bond and phosphoester bond is that phosphodiester bond forms when a sugar molecule binds with a phosphate group and a hydroxyl group whereas a phosphoester bond forms when a sugar molecule binds with a phosphate group. Phosphoester and phosphodiester bonds are common in biochemical molecules. Phosphodiester bond is the linkage […]
Difference Between Phycocyanin and Allophycocyanin
The key difference between phycocyanin and allophycocyanin is that phycocyanin absorbs and emits at shorter wavelengths than allophycocyanin. Phycobiliproteins are a family of water-soluble proteins that are present in cyanobacteria and certain algae species. Phycocyanin and allophycocyanin are two major members of this family. CONTENTS 1. Overview and Key Difference 2. What is Phycocyanin 3. What is Allophycocyanin 4. Similarities Between […]
Difference Between Receptor and Effector
The key difference between receptor and effector is that receptor is a cell or a group of cells in a sense organ that receives a particular stimulus while an effector is an organ that produces a response to the stimulus. Receptor, central nervous system, and effector are three components of reflex actions of the nervous […]
