WITH 100% SOLVED ANSWERS!!
Hydrogenation - CORRECT ANSWER-moving the double bond to a different side to
make it more shelf stable and creating trans fats
Phospholipids are triglyceride derivatives in which a phosphate group replaces one fatty
acid... Which makes it... - CORRECT ANSWER-partially hydrophobic and hydrophilic
aka amphipathic
major phospholipid produced by the liver, key building block of the lipid bilayer - eggs
and liver - CORRECT ANSWER-Lecithin
signaling hormones that exert local control over multiple functions in the body -
CORRECT ANSWER-Eiconasoids
Plant fats are... - CORRECT ANSWER-monosaturated and polyunsaturated fats
What breaksdown fat - CORRECT ANSWER-lingual lipase and ebner gland
stomach only breaks down butterfat
SI releases cholecystokinin when fat is here which triggers the gallbladder to release
bile
pancreatic lipase to breakdown triglycerides.
Micelles - CORRECT ANSWER-when bile salts surround monoglycerides for absorption
- high cholesterol medications get rid of bile salts so that this absorption can't happen
Is bile reabsorbed? - CORRECT ANSWER-yes - by the hepatic portal vein
What is the chemical group name for fats? - CORRECT ANSWER-Glycerides
How many essential, nonessential, and conditional amino acids are there? - CORRECT
ANSWER-9 essential
5 nonessential if you're eating your essentials
and conditional on which disease you have that requires these
Negative vs Positive nitrogen balance - CORRECT ANSWER-negative- excreting more
nitrogen than eating (very harmful, body can feed on muscles of the body)
positive- holding more nitrogen than excreting (growth periods)
Blood proteins - CORRECT ANSWER-Hemoglobin - oxygen carrying and Transferrin -
iron transport
, Complete proteins - CORRECT ANSWER-are of animal origin and have all essential
amino acids (soy is complete even though it's a plant) (gelatin is not complete even
though it's of animal origin)
Zymogens - CORRECT ANSWER-stored protein enzymes and proenzymes
Digestion of proteins - CORRECT ANSWER-mouth - mechanical
begins in stomach -Hydrochloric acid
-HA activates pepsinogen to become pepsid
-Rennin - only in children to help digest milk
SI - food activates trypsinogen to become trypsin
-which then activates chymotrypsin(ogen) and (pro)carboxypeptidas(attacks acid end)
-Aminopeptidase: attacks nitrogen end
- Dipeptidase: takes all remaining dipeptides to make them single amino acids
Dietetics - CORRECT ANSWER-The use of evidence-based practices in the area of
food and nutrition to improve and maintain good health
Health vs Wellness - CORRECT ANSWER-Health - complete well being
Wellness - full potential development
Essential Nutrients - CORRECT ANSWER-carbs, protein, fats, minerals, vitamins and
water
Nonessential Nutrients - CORRECT ANSWER-amino acids and cholesterol

ANSWER-TEF - 10 %
Physical Activity - 15%-30%
convert kilocalories (kcal) into kilojoules (kJ) - CORRECT ANSWER-multiply the
number of kilocalories by 4.184
Whole grain vs refined whole grain - CORRECT ANSWER-refined only has 1 or 2
layers; whole has all 3 layers
Dextrin - CORRECT ANSWER-group of carbohydrates broken down in the mouth
because of amylase saliva
Ptyalin - CORRECT ANSWER-aka salivary amylase
Cellulose - CORRECT ANSWER-nondigestable dissacharide that adds bulk to the diet
