Flashcards in Overview of Protein Biochemistry Deck (13):
1

What are essential amino acids?

Those that the body can't make

2

Conditionally essential amino acids are those that _____________.

the body can make, but the substrates needed to make them may be quite finite

3

The amino acid ______ is used to shuttle nitrogen out of the body.

glutamine

4

Amino acids can be _______-genic or _________-genic.

keto; gluco

5

There are two ways that proteins can be degraded within cells: ________________.

lysosome degradation and ubiquitination

6

ALT converts ________________.

alanine to pyruvate (for gluconeogenesis)

7

AST converts ________________.

aspartate to oxaloacetate

8

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.

9

___________ is a post-translationally modified amino acid that is part of the urea cycle.

Ornithine

10

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

11

___________ becomes aspartate when you take the amino group off.

Oxaloacetate

12

___________ becomes glutamate when you add an amino group to it.

Alpha-ketoglutarate

13

Glutamine synthase absorbs __________ from tissues and puts it onto ____________.

NH3; glutamate
