Carageenan is a poly-saccharide used as gelling agent in many foods. The most commons source of this polysaccharide is seaweedse is the most abundant sugar i. The consequence is that they are all the maximum distance apart.tt
Agarose is a polymer of....................................... It is a polysaccharide which forms a very open gel-like structure. It is used as a gel filtration medium because of this property. The pores are large and allow entry of molecules of molecular mass in the millions
Fructose is a 6-carbon sugar found in combination with glucose in sucrose. It has a 5-membered furanose ring.the most abundant sugar in nature probably because it ionsequence is that they are all the maximum distance apart.tt

Glucose occurs in solution mostly in the pyranose ring form but approx. 1% of the molelules have this open chain conformation and the result is that both alpha and beta anomer of the ring form are possibleis the most abundant sugar in nature probably because it is the most stable. Note how all of the hydroxyl groups are arranged in an equatorial manner. The consequence is that they are all the maximum distance apart..
Glucose occurs in solution mostly in the pyranose ring form. This form of the sugar has the hydroxyl group arranged equatorially. This probably explains why it is the most abundant sugar in nature. This arrangement give maximum stability to the molecule but approx. 1% of the molelules have this open chain conformation and the result is that both alpha and beta anomer of the ring form are possibleximum distance apart..

This probably explains why it is the most abundant sugar in nature. This arrangement give maximum stability to the moleculeemolelules have this open chain conformation and the result is that both alpha and beta anomer of the ring form are possibleximum distance apart..
Phosphofructokinase is an important allosteric enzyme in the glycolysis pathway. The video shows ......which forms a very open gel-like structure. It is used as a gel filtration medium because of this property. The pores are large and allow entry of molecules of molecular mass in the millions
Rubisco is the most abundant protein on Earth. It catalyses the fixation of carbon dioxide by ribulose 1,5 bisphosphate to yield two molecules of 3-phosphoglycerate. The video shows the rubisco dimer with a molecule of ribulose 1,5 bisphosphate (red, spacefill) bound to each unit.
Phosphofructokinase catalyses the phosphorylation of fructose -6-phosphate to yield fructose 1,6 bisphosphate. This is an important allosteric enzyme. The video shows ADP (red) and fructose-6-phosphate (yellow) bound to the active site. A further ADP (red) is bound at the allosteric site on the molecule. The purple spheres are Mg ions.
Lactate dehydrogenase catal-yses the reduction of pyruvate to lactate using NADH as cofactor. The video shows pyruvate (purple) and NAD (red), spacefilled and bound at the active site of the enzyme. The enzyme is shown as a green wireframe model..........

HIV proteinase is an aspartate proteinase involved in the processing of a polyprotein coded by the AIDS virus. It has two identical subunits (green and blue). The video shows an inhibitor, A-74704, (red, spacefilled) bound in the active site tube formed when two flaps close on the substrate.ll of the hydroxyl groups are arranged in an equatorial manner. The consequence is that they are all the maximum distance apart..
Dihydrofolate reductase catal-yses the reduction of dihydrofolate to tetrahydro-folate. It is a vital enzyme in one-carbon metabolism. The video shows NADPH (red) and methotrexate, an inhibitor, (white) bound to the active sit of the enzyme...aximum stability to the moleculeemolelules have this open chain conformation and the result is that both alpha and beta anomer of the ring form are possibleximum distance apart..
