- What are the functions of carbohydrates? Differentiate the class of carbohydrates and their chemistry Compare and contrast proteoglycans, glycoproteins, and glycosaminoglycans. Cite examples for each Give the Unique Feature and Important Function of each: Polysaccharide Chondroitin Нераrin Hyaluronate Dermatan Sulfate Keratan Sulfate Mucinarrow_forwardMild alkaline hydrolysis of glycophospholipids leads to, as major products, 1. Glycerol 2. Glycerol and L-glycerol 3-phosphate 3. Sphingosine 4. Choline O 2 O 4 O 3arrow_forwardLipids are a group of molecules that can be divided into five major subgroups based on their structure and function in the body. Give the specific name to each of the following lipid subgroups: a.) ___________________________: long chain hydrocarbons with a carboxyl groups, parts of Triglycerides and phospholipids b.) ____________________________: critical mediators of immune response c.) ____________________________: fat and oil in food and body d.) ____________________________: contain lipid hormones and cholesterols e.) ____________________________: major component of cell membranesarrow_forward

Sphingolipids all have a palmitate derivative that is ester-linked to the sphingosine backbone. 2. The addition of cholesterol will always lead to an increase in the rigidity of a lipid bilayer. 3. Glycolipids may have a sphingosine or a glycerol backbone to which a sugar moiety is attached. 4. All lipid molecules are characterized by the presence of a carboxylic acid functional group.
