Question

6. Use on-line resources to find out the lipid profile and composition in peanuts, avocado, cow liver and egg 7. User on-line resources to learn how researches use thin layer chromatography to identify various types of lipids present in food samples.

please answer both question 6 and 7 and make sure its correct before answering.

Answer 1

Answers are as follows :-

6 food 0 Peanuts ② Avocado Lipid Profile composition Monounsaturated (MUFA) found in 1 composition ; moisture (3,26), Protein Peanuts - Cholesterol, HDL tt, (6.25 - N2) 21.04, upid (50.33), mineral triacylglycensl. fatty acid - Palmi-l and other carbohydrates. Hic acid, stearic acid, oleic acid , linoleic acid amd arachidic acid. Monounsaturated fatty acids (MUFA) One half an owocado is a nutrient Fly, Polyunsaturated fatty acid | and Phyto chemical dense food, (PUFA) 134. , dietary fiber (416g), total sugar Saturated fatty acids (SFA) 16%. (0.2g) , Potassium (345 mg), sodium (5.5mg), vitamin A (0.5 mg RAL) vitamin c (6.0ng), vitamin E (1.3ing) vitamin ko (144g), folate (60mg). Saturated fat, triacylglycerols, vitamin B12 : 3,460% of the Rol.. triglycerides and gucerslipids.

to Thin la various type Thin layer chromatography to identify of lipids in food sample :- Thin layer chromatography used for the separation and indentification of upids. Phospholipids com be separated by ID or 2-0 Chromatography. 2-0 Thin layer chromatography use in more sensitive separation. Procedure 0 sample application as a small sput. I help of capillary 1. tube) 0 Then dried the sample in air. ③ Thin layer chromatography the plate is put in the 1. Chromatography jar and closed its lid. @ The system is allowed to be static until the Solvent- movee to a proper distance from baseline. € After that TLC Plate is taken out and dried. the chamber TLC Phatte sputting line t o Mobile phase © The liquid slowly stise up by capillary action separation occurs as the components with the higher affinity for moring Phase migrate faster. 0 After that visualized UV fluorescece or developed - with a chemical reagent spray colour spots are seem @ steffens Different fats (lipid) are migrati different Position. ber which we can able to identify different tipids,
