protein metabolism Flashcards
what is an amino acid pool?
the total supply of amino acids in the body
can amino acids be stored?
no
what can we use amino acids for?
- fuel through catabolism
- muscle and albumin structure
- function: enzymes, neurotransmitters
what is a protein turnover?
the continuing process in which body proteins are hydrolyzed and resynthesized
what are the 3 stages for Amino Acid Catabolism Nitrogen?
transamination, deamination, urea formation
what is the transamination stage?
where we take amino acid and turn it into glutamate and aspirtate
what happens in the deamination stage?
glutamate will go undergo deamination to form ammonium ion which would go to the urea formation cycle
what happens during the urea formation cycle?
ammonium is turned into urea with aspartate
what happens after urea is formed?
diffuses out of liver cells into the blood, kidney filters it out, excreted in urine
outcome of transamination?
makes a new amino acid
outcome of deamination?
oxidative process removing amino group
outcome of urea formation?
takes two ammonia and makes urea
glucogenic amino acid
has a carbon skeleton that can be turned into glucose
ketogenic amino acid
carbon skeleton that can be turned into acetyl CoA
majority of proteins will be what type of amino acid?
glucogenic amino acid
