ASC 378 EXAM 2 STUDY GUIDE
Plant Carbohydrates: Structural - Answers - Cell Wall
1.) Pectins, B-glucans, Galactans (Neutral Detergent Soluble Fiber, Neutral Detergent
Soluble CHO)
2.) Hemicelluose (NDF)
3.) Cellulose (ADF & NDF)
Plant Carbohydrates: Non-structural - Answers - Cell Contents
1.) Organic Acids (Neutral Detergent Soluble CHO, Neutral Detergent Soluble Fiber)
2.) Sugars (Neutral Detergent Soluble CHO)
3.) Starches (Neutral Detergent Soluble CHO)
4.) Fructants (Neutral Detergent Soluble CHO)
The three classes of nutrients that supply energy - Answers - 1.) Carbohydrates - major
source of energy
2.) Fats (lipids) - second major source of energy
3.) Protein (amino acids) - only provide some energy
Carbohydrates function as an (BLANK) source for the body - Answers - Energy
Photosynthesis - Answers - 6CO2+ 6H2O + 673 kcal ⇒C6H12O6+ 602
Carbohydrates are classified based on the number of sugar units they contain -
Answers - Monosaccharide: breaks down into one simple sugar
Disaccharide: breaks down into two simple sugars (ie. sucrose)
Trisaccharide: breaks down into three simple sugars
Polysaccharide: breaks down into more than three simple sugars
Monosaccharide - Answers - Simple sugars
Subclassed according to number of carbons in a chain: triose (3), tetrose (4), pentose
(5), hexose (6)
Hexoses (C6H12O6) - Answers - Monosaccharides that play a significant role in
nutrition both as food components & as products of body metabolism
The Four Types of Hexoses - Answers - 1.) Glucose
2.) Galactose
3.) Fructose
4.) Mannose
Glucose (dextrose) - Answers - Occurs freely in natures
The most important hexose in nutrition
Prepared commercially by hydrolysis of cornstarch
1.) Principle energy source in the blood
