NS 3310- Prelim I
Alpha-D-glucose: hydroxyl group (-OH) down. If OH is down, then it is referred to as alpha.
Beta-D-galactose: -OH pointed up.
Fructose: 5 carbon ring (still 6 carbon sugar): -OH in Beta (up)
Outline for Prelim II:
Lipogenesis: making f.a from acetyl CoA (acetyl CoA comes from carbs and a.a.- not from diet directly)
*ACC- acetyl-coA carboxylase > converts acetyl CoA to malonyl coA > palmitate
CPT1- transports acyl coA into mitochondria for B-o
Rickets,- calcium deficiency. From lack of vitamin D, which is synthesized in the skin
Vitamin D is actually a hormone. Dont need to consume Vitamin D as long as you get enough sun
In the presence of UV light:
7-dehydrocholesterol -> Vitamin D3
Outline for Final:
Not found in plant kingdom. Fat soluble vitamin
B-carotene- precursor. Not biologically active
B-caroteine> Retinal. 50% cleavage efficiency. So need twice as much B. C. as retinal.
Retinal then gets converted to retinol (bio
