(a)
Interpretation:
The given sugar pair (D-glyceraldehyde and dihydroxyacetone)
should be determined.
Concept introduction:
Carbohydrates are a large group of organic compounds that are present in foods, living tissues. These include sugars, cellulose, and starch. Anomers are the glycosides or cyclic monosaccharides that are epimers. These are different from each other in the configuration of C-1 (aldoses) or at C-2 if (ketoses).
(b)
Interpretation:
The given sugar pair should be determined.
Concept introduction:
Carbohydrates are a large group of organic compounds that are present in foods, living tissues. These include sugars, cellulose, and starch. These are comprised of hydrogen and oxygen in a similar ratio as in water (2:1). They are usually broken down to release the energy in the animal body. These are of three types: monosaccharides, disaccharides, and polysaccharides.
(c)
Interpretation:
The given sugar pair (D-glucose and D-fructose) should be determined.

- Example 1: 1. Suppose an enzyme (MW = 5,000 g/mole) has a concentration of 0.05 mg/L. If the kcat is 1 x 10 s, what is the theoretical maximum reaction velocity for the enzyme? A) 1050 µM/s. B) 100 µM/s. C) 150 μM/s. D) 105 μM/s.arrow_forwardIn 1956, E. P. Kennedy and S. B. Weiss published their study of membrane lipid phosphatidylcholine (lecithin) synthesis in rat liver. 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. Determine the optimal pH for this enzyme and characterize the enzyme activity at different pH values. -O-P-O-CH2-CH₁₂-N(CH3)3 Phosphocholine H₂C-O-C-R HC-O-C-R2 + + + Cell fraction + ? HC-O-P-O-CH₁₂-CH₂-N(CH), O Phosphatidylcholine The researchers then centrifuged the broken cell preparation to separate the membranes from the soluble proteins. They tested three preparations: whole extract, membranes, and soluble proteins. Table 1 summarizes the results.

They determined its structure from the following observations and experiments. (a) Qualitative analysis showed that X was composed entirely of C, H, and O. A weighed sample of X was completely oxidized and the H2O and CO2 produced were measured. This quantitative analysis revealed that X contained 40.00% C, 6.71% H, and 53.29% O by weight. (b) The molecular mass of X, as determined by mass spectrometry, was 90.00 atomic mass units (u). (c) Infrared spectroscopy showed that X contained one double bond. (d) X dissolved readily in water, and the solution demonstrated optical activity when tested in a polarimeter. (e) The aqueous solution of X is acidic. What is the empirical formula of X?arrow_forward
