1. Proteoglycans, such as heparan sulfate are defined as having sulfated glycosaminoglycans that are covalently joined to membrane proteins or secreted proteins. a. Which weak intermolecular force of attraction allows the proteoglycans to interact with extracellular proteins, such as antithrombin (AT) in the diagram below? b. Provide the full name of the moiety on the proteoglycan that interacts with the protein. c. Provide the name of one of the amino acid residues within the protein (AT) that is likely to interact with the proteoglycan Conformational activation Factor Xa AT Heparan sulfate LNS domain A conformational change induced in the protein antithrombin (AT) on binding a specific pentasaccharide NS domain allows its interaction with blood clotting factor Xa, preventing clotting.

Intelligence refers to the intellectual functioning that compares a person's intelligence quotient (IQ) with other people of the same age. In other words, it is the ability to understand circumstances or situations and arrive at appropriate solutions. Bo…
