As seen at the end of Section 16.10, a deficiency in vitamin D can cause a bonesoftening disease called rickets, so many fo including milk and cereals, are fortified with vitamin D. Our bodies synthesize vitamin D when our skin is exposed to sunlig out the lack of outdoor exercise by today's children, in conjunction with regular use of sunscreen, may be contributing to a 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: 40.. Vitamin D3 CH3 H CH3 Select the number of each feature present in vitamin D3.

Question
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)
