Textbook Question
Chapter 25, Problem 25.44P
Digitalis is a preparation made from the dried seeds and leaves of the purple foxglove, Digitalis purpurea, a plant native to southern and central Europe and cultivated in the United States. The preparation is a mixture of several active components, including digitalin. Digitalis is used in medicine to increase the force of myocardial contraction and as a conduction depressant to decrease heart rate (the heart pumps more forcefully but less often).

Alkaloids are basic nitrogen-containing compounds of plant origin, many of which are physiologically active when administered to humans. Ingestion of coniine, isolated from water hemlock, can cause weakness, labored respiration, paralysis, and eventually death. Coniine is the toxic substance in the “poison hemlock” used in the death of Socrates. In small doses, nicotine is an addictive stimulant. In larger doses, it causes depression, nausea, and vomiting. In still larger doses, it is a deadly poison. Solutions of nicotine in water are used as insecticides. Cocaine is a central nervous system stimulant obtained from the leaves of the coca plant.Classify each amino group in these alkaloids according to type (primary, secondary, tertiary, aliphatic, aromatic, heterocyclic).
As seen at the end of Section 16.10, a deficiency in vitamin D can cause a bonesoftening disease called rickets, so many foods,
including milk and cereals, are fortified with vitamin D. Our bodies synthesize vitamin D when our skin is exposed to sunlight,
but the lack of outdoor exercise by today's children, in conjunction with regular use of sunscreen, may be contributing to a rise
in the disease. The amount of vitamin D3 in fortified foods and fish can be measured by UV-Vis spectrometry. (J. Agric. Food
Chem. 2009, 57, 2135-2146.) Using Woodward-Fieser rules, estimate the expected Amax for vitamin D3:
HO..
Vitamin D3
CH3
nm
H CH3
Select the number of each feature present in vitamin D3.
Base value (conjugated diene) = 217 nm
Number of additional double bonds:
Number of auxochromic alkyl groups:
Number of exocyclic double bonds:
Number of homoannular dienes:
Estimated Amax=
✓ (+30 each)
✓ (+5 each)
✓ (+5 each)
(+39 each)
For each of the following statements, indicate whether they are true or false and, in the second case, correct them appropriately:
a) In biological systems, copper is often found in the form of blue proteins, so called because they absorb light from 450 to 500 nm
b) Aldehyde oxide reductase is a copper enzyme that oxidizes aldehydes to carboxylic acids
c) The only metal that carries oxygen transport in living beings is iron
d) Superoxide dismutase catalyzes the decomposition of the anion superoxide in water and hydrogen peroxide
e) Holochromodulin is activated when insulin levels decrease, binding to its receptors.
f) Ferredoxins are metalloproteins present in the liver of all animals, whose purpose is to store iron

- Glutathione is a tripeptide whose function is to destroy harmful oxidizing agents in the body. Oxidizing agents are thought to be responsible for some of the effects of aging and to play a causative role in cancer. Glutathione removes oxidizing agents by reducing them. In the process, glutathione is oxidized, resulting in the formation of a disulfide bond between two glutathione molecules. An enzyme subsequently reduces the disulfide bond, returning glutathione to its original condition so it can react with another oxidizing agent.a. What amino acids make up glutathione? b.
