The key difference between PLA and PLGA is that PLA is polylactic acid, which is synthesized via the condensation reaction of lactic acid, whereas PLGA is poly(lactic-co-glycolic acid), which is synthesized via the copolymerization of glycolic acid and lactic acid. Both PLA and PLGA are polymer substances having a thermoplastic nature. However, they are different […]
Difference Between Bioassay and Chemical Assay
The key difference between bioassay and chemical assay is that bioassay measures the concentration or activity of a substance by its effect on living cells or tissues while chemical assay analyzes a substance in a sample using a set of chemical procedures. Assay is an investigative procedure which measures the presence/absence or the amount of […]
Difference Between Catenation and Allotropy
The key difference between catenation and allotropy is that catenation refers to the biding of an element to itself, forming chain or ring structures, whereas allotropy refers to the existence of different physical forms of the same chemical element. Although both catenation and allotropy express a similar idea about the different arrangements of atoms of […]
Difference Between Concentric and Eccentric Contractions
The key difference between concentric and eccentric contractions is that concentric contraction causes muscles to shorten while eccentric contractions cause muscles to elongate. Muscle contraction is a complex process which changes the length of the muscle fibers. Muscle fibers generate tension. It involves the interaction between contractile proteins actin and myosin in the presence of calcium. […]
Difference Between Fundamental Particles and Elementary Particles
The key difference between fundamental particles and elementary particles is that fundamental particles are fundamental constituents of matter whereas elementary particles are the smallest known building blocks of the universe. We often use the names fundamental particles and elementary particles as synonyms. But there is a difference between fundamental particles and elementary particles because the […]
Difference Between Viscoelastic and Viscoplastic
The key difference between viscoelastic and viscoplastic is that viscoelastic materials show both viscous and elastic properties when undergoing deformation, whereas viscoplastic materials show unrecoverable deformation. Viscoelasticity and viscoplasticity are described regarding the properties of polymer materials. Both these terms describe the behaviour of a polymer material during the deformation of the polymer. CONTENTS 1. […]
Difference Between Stabilizing and Balancing Selection
The key difference between stabilizing and balancing selection is that stabilizing selection is a type of natural selection which favours average phenotypes in a population while balancing selection is the maintenance of multiple alleles of a gene within a population in order to enhance genetic diversity. Stabilizing selection is a type of natural selection that […]
Difference Between Calcination and Pyrolysis
The key difference between calcination and pyrolysis is that calcination is done in the presence of a limited amount of air or oxygen, whereas pyrolysis is done in the absence of air. Calcination and pyrolysis are two forms of combustion reactions that are different from each other according to the amount of air that is […]
Difference Between Orthotropic and Anisotropic
The key difference between orthotropic and anisotropic materials is that the orthotropic materials show similar results when similar stimuli are applied in only three mutually perpendicular directions whereas the anisotropic materials show different results when similar stimuli are applied in all possible directions. All materials we know have chemical and physical properties. These physical properties can be […]
Difference Between LPS and LOS
The key difference between LPS and LOS is that LPS has a very high molecular weight, whereas LOS has a low molecular weight. Both LPS and LOS are bacterial lipopolysaccharides. The term LPS stands for lipopolysaccharide while the term LOS stands for lipooligosaccharide. We can find these organic molecules in the outer membrane of gram-negative […]
