Question
Chapter 25, Problem 25.30AP
Interpretation Introduction
Interpretation:
The glucogenic amino acid has to be defined with three examples.
Concept introduction:
- The carbons atoms of the amino acids are
metabolized through two different pathways are called ketogenesis and gluconeogenesis. - Gluconeogenesis is the process of formation of glucose from non-carbohydrates, in which the pathway leads to the formation pyruvate or the intermediates of citric acid cycle.

Suppose you wanted to make a buffer of exactly pH 7.00 using KH2PO4 and Na2HPO4. If the final solution was 0.18 M in KH2PO4, you would need 0.25 M Na2HPO4. Now assume you wish to make a buffer at the same pH, using the same substances, but want the total phosphate molarity ([HPO42−]+[H2PO−4]) to equal 0.20 M. What concentration of the Na2HPO4 would be required?

Their hypothesis was that phosphocholine joined with some cellular component to yield lecithin. In an earlier experiment, incubating 32 P-labeled phosphocholine at physiological temperature (37 °C) with broken cells from rat liver yielded labeled lecithin. This became their assay for the enzymes involved in lecithin synthesis.
