208
Q

What EFA is required by all mammals?

A

Linoleic acid and alpha-linolenic acid

209
Q

Unsaturated fatty acids are numbered based on the position of the first double bond.
n-3, n-6, or n-9. The liver cannot place a bond until n-7 meaning that the fatty acids that have a bond before n-7 must be taken in from the diet. This is why linoeic acid 18 c; n-6, and alpha linolenic acid (18 C, n-3) must be ingested.

A

Examples of fatty acids
Saturated= Palmitic acid
Monunsaturated= oleic acid
Polyunsaturated= linoleic, alpha-linolenic, arachidonic acid

210
Q

Biosynthesis of FA

A

Glucose/ AA are broken down to acetyl CoA which is used to form saturated FA, 16 or 18 C
These can be desaturated to form monunsaturated FA of n-7 and n-9 FA families with certain enzymes. These enzymes are active when eating a low fat, high CHO diet such as an herbivore’s diet. Dogs and cats have limited enzyme activity when consuming high fat diets and they directly use and store dietary FA….if a cat ingests rancid fat, they can stored rancid fat= steatitis

211
Q

Why is arachidonic acid essential to feed in the diet of cats but not dogs?

A

Dogs are able to synthesize arachidonic acid if linoelic acid is provided in the diet because it has the enzyme delta 6 desaturase

212
Q

What other FA does the cat require in the diet because it lacks delta 6 desaturase?

A

EPA and DHA (not known if EPA is provided whether or not DHA can be made)
Normally this can be made from alpha-linolenic acid

213
Q

What are sources of n-6 PUFA (linoleic acid)?

A

Corn oil, cottonseed oil, peanut/safflower/sunflower oil, olive/soybean/canola oil, primrose oil

214
Q

What are sources of n-3 PUFA ,specifically a-linolenic acid?

A

Flaxseed/inseed oil= main sources, canola oil, soybean oil

215
Q

Which source of n-3 PUFA contains EPA and DHA?

A

Fish oil, cold water fish and menhadel oil

216
Q

Which FA helps improved CNS development and the retina of the eye and should be provided in puppy food?

A

DHA

should at least have EHA in the diet to convert to DHA

217
Q 
Which FA is found in phsopholipid cerimides and enhances cell adhesion and is need for an effective water barrier for the epidermis?
A) Alpha-linolenic acid
B) Arachidonic acid
C) Eicospentaenoic acid
D) Linoleic acid
E) Docosahexaenoic acid
A

D

18:2n-6

218
Q 
Which FA may contribute to the epidermal water barrier and also provides a sparing effect of linoleic acid in dogs as they compete for the same enzyme?
A) Alpha-linolenic acid
B) Arachidonic acid
C) Eicospentaenoic acid
D) Linoleic acid
E) Docosahexaenoic acid
A

A

18:3n-3

219
Q 
Which FA generally comprises 20-25% of total FA of he cell membrane phospholipids of the skin and other tissues?
A) Alpha-linolenic acid
B) Arachidonic acid
C) Eicospentaenoic acid
D) Linoleic acid
E) Docosahexaenoic acid
A

B

20:4n-6

220
Q 
Which FA is a competitive substitute for AA and is said to have anti inflammatory effects?
A) Alpha-linolenic acid
B) Arachidonic acid
C) Eicospentaenoic acid
D) Linoleic acid
E) Docosahexaenoic acid
A

C

221
Q

When feeding fish oils, what is the minimum amount of time it takes to see anti inflammatory effects?

A

12 weeks

EPA and DHA

222
Q

CS of FA deficiency

A

Poor growth/weight gain, skin changes= matting, scaly skin, discoloration, increase in water loss; infertility and poor wound healing

223
Q

EHA is synthesized in response to:

A

Proinflammatory factors such as COX products= prostaglandins and thromboxanes and lipoxygenase products= leukotrienes

224
Q

Which of the following is false of physiology and metabolism of n-3 vs n-6 PUFA?
A) There is interconversion
B) There is a competitive equilibrium between the two
C) n-3 are more effective in inhibiting n-6 metabolism than vice versa
D) all are true

A

A

225
Q

Which FA are beneficial because they reduce immune reactivity by regulation production and function of cytokines?

A

n-3, specifically eicosanoids (EHA)

226
Q

what are potential side effects of increasing n-3 PUFA?

A

undesirable immune suppression when giving vaccines; increases the patients oxidative load= may have to Vit E for antioxidant function…if Vit E is decreased lymphocyte proliferation and cytokine production is adversely affected

227
Q

Are the following roles of FA functional or facilitative?

adding palatability/texture, provides dense calorie source, stored as E, promotes fat sol vitamin absoprtion

A

Facilitative

228
Q

Are the following roles of FA functional or facilitative?

cell regulation/metabolism, EFA requiremnet, some are conditionally essential, inflammatory response alteration

A

Functional
