Flashcards in Overview of Protein Biochemistry Deck (13):
What are essential amino acids?
Those that the body can't make
Conditionally essential amino acids are those that _____________.
the body can make, but the substrates needed to make them may be quite finite
The amino acid ______ is used to shuttle nitrogen out of the body.
Amino acids can be _______-genic or _________-genic.
There are two ways that proteins can be degraded within cells: ________________.
lysosome degradation and ubiquitination
ALT converts ________________.
alanine to pyruvate (for gluconeogenesis)
AST converts ________________.
aspartate to oxaloacetate
Trace the pathway by which nitrogen leaves the body.
It follows a transamination reaction to glutamate (from an amino acid) and then glutamate dehydrogenase pulls NH3 off.
___________ is a post-translationally modified amino acid that is part of the urea cycle.
The first key step in protein degradation is ______________.
absorption of NH4 from proteins by carbamoyl phosphate; the product of this reaction enters the urea cycle and absorbs another amine group from aspartate to become urea
___________ becomes aspartate when you take the amino group off.
___________ becomes glutamate when you add an amino group to it.
