Key Difference – TH1 vs TH2 Helper Cells Type 1 T helper (TH1) cells and Type 2 T helper (TH2) cells are two sub types of T helper cells that can be distinguished by the type of cytokines that they secrete. TH1 cells secrete interferon-γ (IFN-γ) and tumour necrosis factor-α (TNF-α) and mainly protect the organism against intracellular pathogens. […]
Difference Between E1 and E2 Reactions
Key Difference – E1 vs E2 Reactions The E1 and E2 reactions are two types of elimination reactions that differ from each other based on the mechanism of elimination; the elimination can be either a one-step or a two-step mechanism. The key difference between E1 and E2 reactions is that E1 reactions have unimolecular […]
Difference Between Blastocyst and Embryo
Key Difference – Blastocyst vs Embryo The key difference between the blastocyst and the embryo is in the developmental stage in which they are formed. The blastocyst is formed at the blastula stage, whereas the embryo is formed when the blastocyst is implanted in the uterine wall. Embryonic development in organisms takes place via […]
Difference Between Supervised and Unsupervised Machine Learning
Key Difference – Supervised vs Unsupervised Machine Learning Supervised learning and unsupervised learning are two core concepts of machine learning. Supervised Learning is a Machine Learning task of learning a function that maps an input to an output based on the example input-output pairs. Unsupervised Learning is the Machine Learning task of inferring a […]
Difference Between Aggregation and Composition in Java
Key Difference – Aggregation vs Composition in Java Aggregation is an association between two objects that describes the “has-a” relationship. The composition is the more specific type of aggregation that implies ownership. The key difference between aggregation and composition in Java is that, if the contained object can exist without the existence of the owning […]
Difference Between SN1 and E1 Reactions
Key Difference – SN1 vs E1 Reactions SN1 reactions are substitution reactions in which new substituents are substituted by replacing existing functional groups in organic compounds. E1 reactions are elimination reactions in which existing substituents are removed from the organic compound. The key difference between SN1 and E1 reactions is that SN1 reactions are substitution […]
Difference Between Glycerophospholipids and Sphingolipids
Key Difference – Glycerophospholipids vs Sphingolipids Glycerophospholipids and sphingolipids are important constituents of the cell membrane. The glycerophospholipids contain a three carbon glycerol backbone while the sphingolipids contain organic aliphatic amino alcohol sphingosine. This is the key difference between glycerophospholipids and sphingolipids. Both are important constituents of the cell membrane that have similar properties. […]
Difference Between Protic and Aprotic Solvents
Key Difference – Protic vs Aprotic Solvents The key difference between protic and aprotic solvents is that protic solvents have dissociable hydrogen atoms whereas aprotic solvents have no dissociable hydrogen atom. A solvent is a liquid compound that can dissolve other substances. There are different forms of solvents that can be categorized basically into […]
Difference Between Operon and Regulon
Key Difference – Operon vs Regulon The operon is a functional DNA unit in prokaryotes consists of several genes that are regulated by a single promoter and an operator. Regulon is a functional genetic unit that is composed of a noncontiguous group of genes regulated by a single regulatory molecule. The key difference between […]
Difference Between Collision Theory and Transition State Theory
Key Difference – Collision Theory vs Transition State Theory Collision theory and transition state theory are two theories that are used to explain the reaction rates of different chemical reactions at the molecular level. Collision theory describes the collisions of gas molecules in gas-phase chemical reactions. Transition state theory explains the reaction rates by […]
