Myrislic acid

Look at the catabolism of myrislic acid shown in I igurc 29.4 to see the overall results of the /S-oxidation patltway. The first passage converts the 14-carbon inyristoyl Co.A into the 12-carbon lauroyl Co. plus acetyl CoA, the second passage converts lauroyl CoA into the lU-carbon caproyl CoA plus acetyl CoA, the third passage converts caproyl CoA into the 8-carbon capryloyl CoA, and so on. Note that the final passage produces hvo molecules of acetyl CoA because the precursor has four carbons. 

Palmihc add (16 0) iS the primary saturated fatty acid in most diets. This compound constitutes about 25% of the fatty acids of beef or pork fat, but only 6-10% of Ihc fatly acids of sunflower, safflower, peanut, or soy oils (see Table 6.8). Dietary palmitic add increases LDL-cholesterol (Grundy and Denke, 1990), Myrislic acid (14 0) is present at high levels in butter fat and in the "tropical oils" palm oil and coconut oil. Although myristic add elevates LDL-cholesterol, it is generally a rather minor component of the diet. Stearic acid (18 0) is also a major component...
