Nitrogen Containing Comp.
In Plants |
Some aa are modified w/in pr--
- non pr-- aa are produced as defense comp. *300 non-pr-- aa are produced in plant [analogs] |
|
|
non-pr-- aa
|
In animal tissues these aa are incorporated into pr-- by accident.
- have toxic effect |
|
|
non-pr-- aa
toxic effect |
As result => inhibit aa uptake
- systhesis of aa - common in legumes, sunflower, and cucumber fam |
|
|
non-pr-- aa
Cananine====> [analog] of arginine |
commone in legumes
can account to about 10 per. dry wght of seed - serves as nitrogen storage compound in seed -defense against gramivored (seed eaters) |
|
|
non-pr-- aa
How do the plant recognize the non- pr-- aa? |
plants hace evovled enzymes that recognizes that non pr-- aa
Which do not incorporate in their pr-----> avoid poisoning themselves |
|
|
non-pr-- aa
Proteinases and Amylases Inhibitors |
Inhibitiors of pr-- and starch digestion
If a plant is attacked by herbivore |
|
|
non-pr-- aa
Proteinases and Amylases Inhibitors - If a plant is attacked by herbivore |
They inhibit proper digestion of cell content---> starve it.
-Effective in both bugs and animals - founs in legumes ex// : phaseolus,vulgaris, kidney bean ( seed about 20% pr-- and 80% CHO) |
|
|
phaseolus,vulgaris, kidney bean
|
( seed about 20% pr-- and 80% CHO)
-contain pr-- inhibitor phasin -make seed inedible to most insects - human cook them and deenature phasin - also contain phaseolamin |
|
|
phaseolamin
|
Amalyase inhibitor
|
|
|
cynogenic gylcosides
|
when cells contain them are broken generate cyanide
-found in seeds of members of the rose family ex// apples peaches apricots, plums, pears -protects plants against insects & herbivores |
|
|
Alkoids
|
Huge group of related compounds
-toxic to mammals |
|
|
Nitrogen Containing Comp.
Alkoids -nicotiana species |
-produces nicotine in response to herbivory
-good insecticide - cause vomiting, diarrea, in ^ [ ] |
