Abstract This study dealt with the measurement of several variables in the blood serum for a group of people in the case of fasting (Ramadan) for (14–16) hours, where the blood serum was withdrawn from people during daylight hours after fasting (5–8) hours and then follow the same people After (15) days of fasting and then after (25) days as well as blood serum samples were collected for the same people one month after the end of the month of Ramadan and the age of people ranged between (19–80)years and both sexes (males and females) are healthy people and do not suffer from any apparent disease. The study focused on measuring the percentage of fatty acids in the three segments separated from serum (cholesterol ester, triglyceride and phospholipids) which were separated by thin layer chromatography and then the esterification of the separated fatty acids was carried out using (BF3/methanol) method. Percentage of fatty acids (SFA, MUFA and PUFA) using a capillary gas chromatography device The results of this study indicated a significant increase in the percentage of saturated fatty acids, a non-significant decrease in the percentage of monounsaturated fatty acids, and a non-significant decrease in the percentage of polyunsaturated fatty acids in The serum cholesterol ester portion of the fasting group compared with the control group The results of this study indicated a significant increase in the percentage (SFA), a non-significant decrease in the percentage (MUFA), and a non-significant increase in the percentage (PUFA) in the Tricyclic serum for serum group The results of this study showed a significant increase in the percentage (SFA), a significant decrease in the percentage (MUFA), and a significant non-significant decrease in the percentage (PUFA) in the serum phosphate fat portion of the fasting group compared with Control group.
