Expert Solution & Answer

Answer to Problem 1E

Correct answer: An amino group or imino group gives a positive charge to a molecule, and a carboxylate or phosphoryl group gives a negative charge to a molecule.

Explanation of Solution

Functional groups are the reactive regions of molecules that are functionalized with these specific groups. The common functional groups are alcohols (-OH), carbonyls (C=O), carboxylic acids (-COOH), amines (-NH₂), and esters (-COOR). They are classified on the basis of their charge and polarity.

The functional groups associated with biomolecules that impart a positive charge on them include amino group (-NH₃⁺) and imino group. They can accept H⁺ and impart a positive charge.

The functional groups that impart a negative charge to the biomolecules are carboxylate group, alcohol group, phosphoanhydride group, and phosphodiester linkages. They release H⁺ and impart a negative charge. These functional groups are present in most biomolecules such as carbohydrates, proteins, and nucleic acids.

In 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 + ?

They tested three preparations: whole extract, membranes, and soluble proteins. Table 1 summarizes the results. Table 1: Cell fraction requirement for incorporation of 32p-phosphocholine into…

Researchers isolated an unknown substance, X, from rabbit muscle. 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?
