4. A list of fatty acids is given below. The number of carbons each contains, as well as the number of double bonds, are listed right after the name. Rank the fatty acids 1-5 from highest melting point to lowest melting point. 1 - highest melting point, 5 - lowest melting point. Palmitic acid (16 carbons, 0 double bonds) Oleic acid (18 carbons, 1 double bond) Linolenic acid (18 carbons, 3 double bonds) Lauric acid (12 carbons, 0 double bonds)...
Which of the following is true of a triacylglycerol? 1) A triacylglycerol rarely contains the same fatty acid at all 3 positions. 2) A triacylglycerol is formed when 3 fatty acids react with the 3 hydroxyl groups of the glycerol moiety. 3) A triacylglycerol always contains the same fatty acid at all three positions. A) B) only. B) A) and B) are both correct C) A) only. D) C) only.
Modify the following fatty acid so that it represents the 18-carbon fatty acid designated 18:2(?9,12). Draw any double bonds in the cis configuration.

The complete hydrolysis of a glycerophospholipid gives glycerol products, two fatty acids (16: 2 Δ9.12 and 16: 3 Δ6.9.12), phosphoric acid and choline in an equimolar ratio. Draw the structure of this lipid.
Please answer all components. Postlab 1) Coconut oil ls omprised of a misture of fatty acids in the form of triglycerides. The most abundant fatty acids in coconut oil are as follows: Lauric acid (48%) oleic acid (6.5%) Myrisitic acid (16%) Palmitic acid (9.5%) Draw the structure of each of these fatty acids: Considering the structures above, explain the relatively high melting point of coconut oll 2) Some oils that are improperly stored (exposed to oxygen) over long periods of...
help with 1 & 2 please 1. Draw the condensed structural formula for the triacylglycerol containing three molecules of palmitic acid (16.0). (5 pts) 2. Consider the condensed structural formula for linolenic acid shown below. (10 pts) CH, CH2CH- CH3-CHT-CH2-=CH-CH-COOH a) Why is this molecule an acid? b) How many total carbon atoms are in linolenic acid? c) Is linolenic acid a saturated, monounsaturated, or polyunsaturated fatty acid? d) Is linolenic acid likely to be a solid or liquid at...
Tor F 1. With the exception of steroids, all lipids contain at least one fatty acid. 2. Some lipids contain monosaccharides as part of their structure. 3. Some lipids contain an amino acid as part of their structure. 4. Glycerophospholipids contain a phosphate portion in their structure. 5. All lipids have a molecule of glycerin as their backbone. 6. Polyunsaturated fatty acids have more than one C-C double bond in their "backbone." 7. Fatty acids are soluble in water. 8....
