Get started for freeGlucose can occur in three forms: two cyclic forms and one open-chain structure. In aqueous solution, only a tiny fraction of the glucose is in the open-chain form. Yet tests for the presence of glucose depend on reaction with the aldehyde group, which is found only in the open-chain form. Explain why these tests work.
Write the sequence of all possible tetrapeptides composed of the following amino acids. a. two phenylalanines and two glycines b. two phenylalanines, glycine, and alanine
A common shorthand notation to draw organic structures is to use lines to represent \(\mathrm{C}-\mathrm{C}\) bonds. For example, the short- hand notation for the two structural isomers of the formula \(\mathrm{C}_{4} \mathrm{H}_{10}\) are: At the end of each zigzag line is a carbon atom. The \(\mathrm{C}-\mathrm{H}\) bonds are omitted in such shorthand notation. Use line notation to illustrate the structural isomers of \(\mathrm{C}_{6} \mathrm{H}_{14}\)
Estradiol is a female hormone with the following structure: How many chiral carbon atoms are in estradiol?
All amino acids have at least two functional groups with acidic or basic properties. In alanine, the carboxylic acid group has $K_{a}=4.5 \times 10^{-3}\( and the amino group has \)K_{b}=7.4 \times 10^{-5} .$ Three ions of alanine are possible when alanine is dissolved in water. Which of these ions would predominate in a solution with \(\left[\mathrm{H}^{+}\right]=1.0 M ?\) In a solution with \(\left[\mathrm{OH}^{-}\right]=1.0 \mathrm{M} ?\)
