Difference Between Neuropeptides and Neurotransmitters

Difference Between Neuropeptides and Neurotransmitters

Key Difference – Neuropeptides vs Neurotransmitters   Neurotransmitters and neuropeptides are chemical molecules involved in the transmission of signals through neurones in the nervous system. Neurotransmitters are different types of low molecular weight molecules including amino acids and smaller peptides. The neuropeptides are one type of neurotransmitters, and they are composed only of peptides [proteins] […]

Difference Between Postulate and Theorem

Difference Between Postulate and Theorem

Key Difference – Postulate vs Theorem   Postulates and theorems are two common terms that are often used in mathematics. A postulate is a statement that is assumed to be true, without proof. A theorem is a statement that can be proven true. This is the key difference between postulate and theorem. Theorems are often […]

Difference Between Hydroxyl and Hydroxide

Difference Between Hydroxyl and Hydroxide

Key Difference – Hydroxyl vs Hydroxide   The two terms hydroxyl and hydroxide sound very similar since both of them have two similar atoms, Oxygen (O=16) and Hydrogen (H=1). Hydroxide is a negative ion with a single charge and hydroxyl is not found in its free form, it is a part of another molecule or […]

Difference Between Anomers and Epimers     

Difference Between Anomers and Epimer

Key Difference – Anomers vs Epimers   Anomers and epimers are both diastereomers. Epimer is a stereoisomer that differs in configuration at only one stereogenic center. An anomer is a cyclic saccharide and also an epimer that differs in the configuration, specifically at the hemiacetal or acetal carbon. This carbon is called the anomeric carbon. […]

Difference Between Cellulose and Hemicellulose        

Difference Between Cellulose and Hemicellulose

Key Difference – Cellulose vs Hemicellulose   Cellulose and hemicellulose are two types of natural polymers that are mainly found in the plant cell walls and are important components of natural lignocellulosic materials. But, these two components are different in the chemical composition and the structure. The key difference between cellulose and hemicellulose is that […]

Difference Between D and L Glucose      

Difference Between D and L Glucose

Key Difference – D vs L Glucose   The “D” and “L” letter indication in the names of D-glucose and L-glucose are used to distinguish the structural differences in the glucose molecule. D-glucose and L-glucose are called enantiomers because their molecular structures are mirror images of each other. Therefore, the key difference between D and […]

Difference Between Inductive Effect and Mesomeric Effect

Difference Between Inductive Effect and Mesomeric Effect

Key Difference – Inductive Effect vs Mesomeric Effect   Inductive effect and mesomeric effect are two types of electronic effects in polyatomic molecules. However, inductive effect and mesomeric effect arise due to two different factors. For example, inductive effect is a result of the polarization of σ bonds and mesomeric effect is a result of […]

Difference Between Staggered and Eclipsed Conformation

Difference Between Staggered and Eclipsed Conformation

Key Difference – Staggered vs Eclipsed Conformation   The two terms, Staggered and eclipsed conformation(two main branches of the Newmann projections) are used in Organic Chemistry to explain the arrangement of atoms in some organic molecules. In terms of stability, staggered conformation is more stable than eclipsed formation. The formation of the staggered confirmation is […]

Difference Between Topology and Topography

Difference Between Topology and Topography

Key Difference – Topology vs Topography   Topology and topography are two words that are commonly misused by many English speakers. Although these two words sound alike, they have very different meanings. Topology is concerned with the geometrical properties and spatial relations that are unaffected by the continuous change of shape or size of figures. […]

Difference Between Hyperconjugation and Resonance

Difference Between Hyperconjugation and Resonance

Key Difference – Hyperconjugation vs Resonance   Hyperconjugation and resonance can stabilise polyatomic molecules or ions in two different ways. The requirements for these two processes are different. If a molecule can have more than one resonance structure, that molecule possesses the resonance stabilisation. But, hyperconjugation occurs in the presence of a σ-bond with an […]
