Antoine Lavoisier - Answer father of nutrition, "life is a chemical process"
Dr. Stephen Babcock - Answer idea for the single plant feeding experiment which stimulated
the Golden Age of Nutrition, Milk fat/Babcock test
Book of Daniel - Answer first recorded nutritional experiment
Dr. William Beaumont - Answer army doc, looked at hole in stomach of Alexio St. Martin
Funk - Answer vitamin after "vital amine"
Lind - Answer scurvy and citrus
6 classes of nutrients - Answer water, carbohydrates, fats, proteins, vitamins, mineral
high dielectric constant - Answer property of water makes it so useful for transporting
nutrients and as a medium for chemical reactions
high latent heat of vaporization - Answer property of water is operating when an animal is
cooled by sweating
high specific heat - Answer helps maintain body temperature
nutritent - Answer chemical that aids in support of life and is needed for normal
growth/function
3 general sources of water - Answer water from feed, metabolic water, drinking water

Which nutrient class comprises most of livestock diets (excluding water)? - Answer
carbohydrates
, what is the difference in elemental composition that partly explains the difference in energy
content of fats and carbs? - Answer Fats contain much less oxygen than carbohydrates, leaving
more carbon and hydrogen relatively, to oxidize to produce energy.

The function of carbs in a diet - Answer to provide energy
function of fats in a diet - Answer supply essential fatty acids, provide energy
proteins are composed of - Answer amino acids
function of protein in diet - Answer to supply amino acids and in excess supply energy
true protein vs crude protein - Answer True protein is composed of amino acids connected
together by peptide bonds in complex molecules, while Crude Protein is our estimate of that,
based on nitrogen content
pentoses - Answer arabinose, xylose, ribose
hexoses - Answer glucose, fructose, galactose, mannose
lactose - Answer glucose + galactose
