15. How many of the fatty acids which the body needs is it unable to synthesize? b. 2 c. 3 d. 4 a. 1
Distinguish between the structure of saturated and unsaturated fatty acids and describe why saturated and unsaturated fatty acids have different melting temperatures
15. The process by which double-bonds in unsaturated fatty acids are converted to single bonds is termed . The 16. Fatty acids are linked to glycerol by a reaction known as opposite chemical process is termed 17. True / False Micelles are lipid bilayers and differ from the phospholipid bilayer of cell membranes only in scale. 18. Triglycerides and even more so phospholipids contain a polar head and a nonpolar tail that results in dual polar-nonpolar nature. These compounds are...
An increased amount of unsaturated fatty acids in cytoplasmic membranes is a molecular adaption of_ since_ thermophiles, unsaturated fatty acids help the membrane remain in a solid state at high temperatures to block excessive transport activity. psychrophiles, unsaturated fatty acids help the membrane solidify at lower temperatures at block transport activity. thermophiles, unsaturated fatty acids help the membrane remain in a semifluid state at high temperatures to help carry out transport and bionergetic functions. O psychrophiles, unsaturated fatty acids help...
which fatty acid is unsaturated
Lipids b. Which fatty acid is unsaturated? c. The melting point of stearic acid is 70°C, and that of oleic acid is 4°C. Explain the difference. From the results of experiment C, how can you tell which is more unsaturated, oleic acid or steari d. acid? 04. How does omitting triethanolamine affect the properties and appearance of the hand lotion? Q5. How does omitting stearic acid affect the properties and appearance of the hand lotion?...
