define dynamic protein turnover
continual degradation and resynthesizing of bodily proteins
what can amino acids be used for
protein synthesis, oxidation, or non-protein metabolites
is dynamic protein turnover accurate
no
describe protein synthesis
DNA is transcribed to RNA
RNA is translated to protein
define intracellular proteases
breaks down proteins marked for degradation, which occurs in all cells
where does amino acid oxidation occur
liver
can amino acids be completely broken down
yes
define ketogenic. what aminos are ketogenic?
oxidized to acetyl CoA, ketone bodies, or FA synthesis
lysine and leucine
define glycogenic. what aminos are glycogenic?
oxidized to glycolytic or CAC intermediates
Glycine, serine, aspartic acid, glutamic acid, glutamine, valine, methionine, histidine, and arginine
what amino acids are both keto and glyco
isoleucine phenylalanine lyrosine and tryptophan
describe ammonia
pulled off amino acid and excreted through fish gills

stored with water
describe uric acid
secreted by birds
entire molecule
describe nitric oxide
synthesized from arginine
increased blood flow and helps with infection
describe creatine
synthesized from arginine
found in muscle, stores ATP, and binds with phosphate to create ATP
describe choline
synthesized from serine
needed for muscle contractions
describe histamine
synthesized from histidine
increased membrane permeability
describe tourine
synthesized from cysteine
not found in cats
describe glutathione
synthesized from cysteine
antioxidant properties
describe CoA
synthesized from cysteine
oxidizes fatty acids
describe thyroid hormone
synthesized from tyrosine
stimulates metabolism
describe NAD
synthesized from tryptophan
describe melatonin
synthesized from tryptophan
helps with sleeping and circadian rhythm
describe carnitine
synthesized from lysine
transports FAs for B-oxidation
how much protein is needed for protein sources
20%+
define oilseed meals
byproducts of vegetable oil production
what does less energy in feedstuff allow for
more protien
what are the 3 deleterious factors of soybean meal
protease inhibitors
lectins
goitrogens
define protease inhibitors
stops protein digestion and causes enlarged pancreas
define lectins
binds to carbs on brush boarder which causes digestive disturbances
define goitrogens
inhibits thyroid hormone production
causes goiter (enlarged thyroid)
