The key difference between proteoglycans and glycoproteins is that the proteoglycans have long unbranched chains with disaccharide units as repeating structures while the glycoproteins have short highly branched glycan chains with no repeating units. Glycoproteins and proteoglycans are two types of molecules that contain both proteins and carbohydrate units. The carbohydrate units are bound covalently to […]

Difference Between Prokaryotic and Eukaryotic DNA Replication
Prokaryotic vs Eukaryotic DNA Replication According to the Watson and Crick model suggested for DNA, one strand of DNA is the complement of the other strand; hence each strand acts as a template for the formation of a new strand of DNA. This process is known as DNA replication. The replication of DNA basically […]
Difference Between Axons and Dendrites
The key difference between axon and dendrites is the function of these two types of cytoplasmic extensions of the neuron. Axon passes nerve impulses away from the cell body while dendrites pass nerve impulses towards the cell body. Neurons are of three main types; motor neuron, sensory neuron and interneuron. All neurons are composed […]
Difference Between Triglycerides and Phospholipids
Triglycerides vs Phospholipids Lipids are carbon-containing organic compounds and are considered as a macronutrient in the food. These compounds do not dissolve in water (hydrophobic), but dissolve in fats (lipophilic). Hence, lipids are digested, transported and absorbed in a different manner when compared to other macronutrients like carbohydrates and proteins. Also, lipids yield more […]
Difference Between Epinephrine and Norepinephrine
Epinephrine vs Norepinephrine Epinephrine (adrenaline) and norepiphrine (noradrenalin) are known as neurotransmitters that belong to a chemical class of catecholamines; which are derived from thyrosin. Both these chemicals regulate attention, mental focus, arousal, and cognition in humans. These neurotransmitters have approximately the same potency for all the receptor types; α and β. Thus, their […]
