Question

estion 6 of 15 Mapa Phospholipids are present in cell membranes. Phosphatidylserine is found in bacteria, yeast, and more complex eukaryotes. In mammals, phosphatidylserine of membranes, and is concentrated in myelin from brain tissue. is located primarily in the inner leaflet Modify the molecule below by replacing the "X" to show a phosphatidylserine You may need to add or remove atoms or bonds. If you make a mistake, you can reset the molecule by clicking on the two red arrows in the tools menu of the answer module. H2-CH CH H2 CH2 CH2 CH2 O He

Answer 1

Map spholipids are present in cell membranes. Phosphatidic acid is a minor constituent of cell membranes, ut it is an important intermediate in lipid biosynthesis. Modify the molecule below by replacing the "X" to show a phosphatidic acid (phosphatidate). You may need to add or remove atoms or bonds. CH H2 CH2-CH2 CH2 CH2 Idenily the faty acid at position 2 of glycerol (the "middle" fatty acid) in this example O O oleic acid (cis-9-octadecenoic acid) stearic acid (octadecanoic acid) Correct. 、O Previous ?
