Nooch Test 3 Questions with Correct Answers lipids - Correct Answer hydrophobic food components (hate water) fats - Correct Answer solid, mixtures of lipids containing a higher percentage of saturated fatty acids mainly from animal sources (margarine, shortening, spreads) oils - Correct Answer liquid, mixtures of lipids containing a higher percentage of unsaturated fatty acids (except coconut oil and palm oil) mostly from plant sources (except fish oil) they spoil more quickly
- major types of lipids in foods and body - Correct Answer triglycerids-most prevelent >95% of all
- degree of saturation-decreased by double bonds
- omega number-3, 6, or 9
- geometric shape-cis or trans 1 / 2
lipids phospholipids-very small amounts sterols-very small amounts (fat soluble vitamins not a major type A, D, E, K) triglycerids - Correct Answer contain four parts glycerol back bone with 3 fatty acids made by condensation reactions usually contain a mixture of different fatty acids glycerol - Correct Answer 3 carbons, an alcohol, back bone of triglycerides fatty acids - Correct Answer main building blocks of lipids molecules determine if they are good or bad for heath how fatty acids can be different - Correct Answer 1. length of carbon chain (4-24)
- essential vs nonessential
- essential fatty acids (must be supplied by diet) - Correct Answer linolenic acid-omega 3
- / 2
Saturated - Correct Answer no double bonds contain maximum only contains single bonds in the carbon chain bad for health unsaturated - Correct Answer 1, 2 or more double bonds contain fewer than maximum hydrogens possible contain one of more double bonds in the carbon chain better for health monounsaturated - Correct Answer one double bond cis(good) or trans(bad) polyunsaturated - Correct Answer two or more double bonds, has omega 3 or 6 omega numbers - Correct Answer location of the last double bond from the omega end of the fatty acid most common are 3 and 6 cis fatty acids - Correct Answer bent (good for health) trans fatty acids - Correct Answer straight (bad for health)
linoleic acid-omega 6 in foods are fatty acids free or bonded to glycerol in triglycerids - Correct Answer bonded to glycerol in triglycerides
