NST 10 Midterm 2 UPDATED ACTUAL
Exam Questions and CORRECT Answers
DIETARY LIPIDS - CORRECT ANSWER -
triglycerides - CORRECT ANSWER - -major form of lipid in body and in food
-composed of 3 fatty acids
-monoacylglyceride (glycerol and 1 fatty acid) and 2 free fatty acids, broken down by lipases
which are stimulated by cck
Phospholipids - CORRECT ANSWER - -help with fat absorption
-transports dietary fats
-part of cell membrane
-made in liver
-in animals and egg yolks, 2 fatty acids, glycerol, phosphorus containing molecule, water and fat
soluble parts
sterols - CORRECT ANSWER - 4 carbon rings
-cholesterol most common
-found in animals
-high cholesterol=increased CHD risk
-plant sterols-decreased CHD risk
-non-essential,
-raises LDL (bad cholesterol)
Omega 6 - CORRECT ANSWER - -linoleic acid

-anti-inflammatory
Essential fatty acids - CORRECT ANSWER - -growth, skin integrity, fertility, structure and
function of cell membranes
-deficiency symptoms: dry skin, liver probs, poor wound healing, infant growth failur
saturated fatty acids - CORRECT ANSWER - -no carbon or double bonds, bend in lipid
structure
-increase risk of heart disease
-monosaturated and poly saturated rats reduce risk of heart disease
unsaturated fatty acids - CORRECT ANSWER - --fatty acid with 1 or more carbon-carbon
double bonds in its chemical structure
pancreatic lipase - CORRECT ANSWER - -break TG into monocygyceride and two free fatty
acids
CCK - CORRECT ANSWER - -stimulates gall bladder to release bile & pancreatic lipase
Bile - CORRECT ANSWER - -created by liver
-stored in gal bladder
-released through common bile duct in duodenum
-essential for digestion/ fat absorption
functions of fatty acids - CORRECT ANSWER - -major source of energy for muscle and liver
tissues
