[Answer] Which fact is most important in causing phospholipids to behave as they do in water?

Answer: Water molecules make hydrogen bonds; The hydrogen bonds in water exclude the nonpolar tails of phospholipids forcing the molecules into a bilayer.

Which fact is most important in causing phospholipids to behave as they do in water? 53 rows · The phospholipids are amphiphilic. The hydrophilic end usually contains a negatively charged phosphate group and the hydrophobic end usually consists of two "tails" that are long fatty acid residues. In aqueous solutions phospholipids are driven … The lipid bilayer (or phospholipid bilayer) is a thin polar membrane made of two layers of lipid molecules. These membranes are flat sheets that form a continuous barrier around all cells. The cell membranes of almost all organisms and many viruses are made of a lipid bilayer as are the nuclear membrane surrounding the cell nucleus and membranes of the membrane-bound organelles in the cell. The lipid bilayer is the barrier that keeps ions proteinsand other molecules where they are needed and prevents them from diff… Sialic acids are a class of alpha-keto acid sugars with a nine-carbon backbone. The term "sialic acid" (from the Greek for saliva σίαλον - síalon) was first introduced by Swedish biochemist Gunnar Blix in 1952. The most common member of this group is N-acetylneuraminic acid (Neu5Ac or NANA) found in animals and some prokaryotes.. Sialic acids are found widely distributed in animal ... Coagulation also known as clotting is the process by which blood changes from a liquid to a gel forming a blood clot.It potentially results in hemostasis the cessation of blood loss from a damaged vessel followed by repair.The mechanism of coagulation involves activation adhesion and aggregation of platelets as well as deposition and maturation of fibrin. Glycolysis is the metabolic pathway that converts glucose C 6 H 12 O 6 into pyruvate CH 3 COCOO − and a hydrogen ion H +.The free energy released in this process is used to form the high-energy molecules ATP (adenosine triphosphate) and NADH (reduced nicotinamide adenine dinucleotide). Glycolysis is a sequence of ten enzyme-catalyzed re...
