ANSC 4394 EXAM 1 STUDY GUIDE 2026
VERIFIED QUESTIONS AND ANSWERS SET
◉ Poor quality hay takes...
Answer: 6-10 days to break down; quality is essential
◉ Carbohydrates uses energy in the body
Answer: -protein synthesis and degradation
-lipid synthesis and mobilization
-nutrient transport
-kidney filitration
-heart beat
-muscle contractions
*ALL these functions REQUIRE ENERGY in the form of ATP
◉ Carbohydrates: Fates of absorbed CHO
Answer: 1. oxidized to provide energy (major function of CHO)
2. stored in liver and muscles as glycogen (minimal)
3. stored in adipose tissue as triglycerides (fat, only excess CHO)
◉ Lipids-Fats-Ether Extract
,Answer: -insoluble in water and soluble in organic solvents
Organic: Benzene or ether
-Concentrated source of energy: 1g lipid=9.45 kcal
1g CHO= 4.2 kcal
2.25 X more energy than CHO
◉ Lipids-Fat-Ether Extract Classification
Answer: 1.simple lipids: true fat(triglycerides) and waxes
2. Compound lipids: phosolipids (phosphorus lipid), glycolipids
(carb and lipid), Lipoprotein
3. Derived lipids: Fatty acids(EFAs, essential: body does not make),
steriods(found only in animal tissue, cholesterol is the most
abundant)
◉ Good cholesterol
Answer: high liproprotein
◉ Bad cholestrol
Answer: low liproprotein
◉ Lipids Physical properties
Answer: -insoluble in water
,-soluble in organic solvents (benzene or ether)
-serves as a source of energy
- serve as a source of essential fatty acids
-composed of fats and oils-most are triglycerides
-contains 2.25 times more energy than carbs
◉ Two Important lipids
Answer: Fats and oils
◉ Fat
Answer: -solid at room temp
-contain chains of Fatty acids with a glycerol molecule(long chain)
◉ Oil
Answer: -liquid at room temp (short chain), readily absorbed
◉ Lipids Major Roles
Answer: -building block of phospholipids and glycolipids
-fuel molecules stored as triglycerides
◉ Saturated Fat
Answer: No double bonds
, ◉ Unsaturated fat
Answer: Double bonds
◉ Microorganisms and animal tissue make
Answer: fatty acids
◉ Lipids Digestion
Answer: -quite high exceeding 80%
◉ Animal=
Answer: even # carbon
◉ Microorganisms
Answer: = odd number carbon
◉ Lipids: Monogastrics Digestion
Answer: digested in small intestines, bile will emulsify the fat for
absorption by increasing the surface area which increases
absorption rate, pancreatic bile will hydrolyze the fatty acids from
the glycerol molecules
