Chondroitin
Proteoglycans are molecules found in the extracellular matrix of connective tissues like cartilage. Chondroitin is a type of glycosaminoglycan (GAG) that is commonly found as part of proteoglycans in cartilage, contributing to its structural integrity.
So, the correct option is (A): Chondroitin
AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
Biomolecules are the most essential organic molecules, which are involved in the maintenance and metabolic processes of living organisms. These non-living molecules are the actual foot-soldiers of the battle of sustenance of life.
There are four major classes of Biomolecules – Carbohydrates, Proteins, Nucleic acids and Lipids.
