Questions and CORRECT Answers
Who was Dr. William Beaumont? - CORRECT ANSWER✔✔- He tried to close a hole in the
stomach of Alexio St. Martin.
What did Dr. William Beaumont propose? - CORRECT ANSWER✔✔- Proposed in 1833
that the noises you hear from your stomach are stomach contractions and not spirit.
Who is Lavoisier? - CORRECT ANSWER✔✔- The Father of Nutrition
What did Lavoisier design? - CORRECT ANSWER✔✔- Designed a calorimeter which
measured the heat produced by the body from work and consumption of varying amounts and
types of foods
Who was Dr. James Lind? - CORRECT ANSWER✔✔- A British naval surgeon who
determined that lemon juice (called limes) kept sailors healthy, preventing scurvy. Hence the
British navalmen are called limeys.
What did Babcock propose? - CORRECT ANSWER✔✔- feed dairy cattle feed from just one
source, all corn plant or all wheat plant
Who were the associates of Babcock that finished his feeding experiment? - CORRECT
ANSWER✔✔- Hart, Humphrey, McCollum, and Steenbock
What did Funk do? - CORRECT ANSWER✔✔- Named vitamins after "vital amines",
thought newly discovered things were amines
What was the earliest recorded nutritional experiment? - CORRECT ANSWER✔✔- Book of
Daniel in the Bible. Daniel was among the finest young men captured by the King of Babylon
when the Babylonians over ran Israel, and was to serve in the King's court. He was to be fed
from the King's table of fine foods and wine. Daniel objected and preferred his own choices,
which included vegetables (pulses) and water. The chief steward was afraid for his head, but
agreed to a trial. Daniel and his friends received his own diet for 10 days and then were
,compared to the King's men. As they appeared fitter and healthier, they were allowed to
continue with their own foods, not defiling themselves with those of the King.
Define a sugar - CORRECT ANSWER✔✔- A term usually denoting a mono or di
saccharide. Technically sugars are polyhydroxy aldehydes or ketones or their anhydrides.
Define monosaccharide - CORRECT ANSWER✔✔- a simple sugar, composed of one sugar
molecule
Define disaccharide - CORRECT ANSWER✔✔- Two units of simple sugars combined.
Example: sucrose is composed of glucose + fructose.
Define polysaccharide - CORRECT ANSWER✔✔- Any chain of sugar molecules composed
of more than two simple sugars is usually called a polysaccharide, although technically there
are trisaccharides as well as monosaccharides and disaccharides.
Define starch - CORRECT ANSWER✔✔- A polysaccharide composed of repeating units of
maltose (glucose + glucose) hooked together with alpha bonds. Quite digestible. Two forms
are amylase and amylopectin.
Define cellulose - CORRECT ANSWER✔✔- A complex carbohydrate composed primarily
of glucose molecules hooked together with beta bonds. Since the beta bond is unbreakable by
any mammalian enzyme (mammals don't make cellulase), it is indigestible without microbial
help.
Define glycogen - CORRECT ANSWER✔✔- A form of polysaccharide that is stored in
animal cells for ready energy. It is made of all glucose, with considerable branching in its
structure. It is only present in very limited quantities for a ready supply of stored energy.
Define glucose - CORRECT ANSWER✔✔- A simple sugar, monosaccharide, hexose. The
most important sugar as blood sugar. Most polysaccharides (starch, glycogen, cellulose) are
made up of repeating units of glucose
Define ribose - CORRECT ANSWER✔✔- A pentose (5 carbon simple sugar) that is in the
structure of RNA and DNA. Its importance nutritionally is much less however, than that
, would indicate because we do not have to consume it; the body can manufacture what is
needed.
Define fructose - CORRECT ANSWER✔✔- A monosaccharide (hexose). Part of sucrose
(talbe sugar). Used in soft drinks as a sweetener in place of more expensive sucrose.
Define galactose - CORRECT ANSWER✔✔-
Define maltose - CORRECT ANSWER✔✔- A dissacharide composed of 2 units of glucose
hooked together with alpha bonds. It forms the repeating unit of starch. Quite digestible.
Define cellobiose - CORRECT ANSWER✔✔-
Define hemicellulose - CORRECT ANSWER✔✔-
Define lignin - CORRECT ANSWER✔✔-
Define amylase - CORRECT ANSWER✔✔-
Define amylopectin - CORRECT ANSWER✔✔- A kind of starch (a polysaccharide)
composed of sugar molecules with considerable branching (as contrasted with amylose which
contains little branching).
Define amylose - CORRECT ANSWER✔✔-
Define cellulase - CORRECT ANSWER✔✔-
Define xylose - CORRECT ANSWER✔✔-
Define acetic acid - CORRECT ANSWER✔✔-
