Which of the following statements about amino acids is/are incorrect? 1. Standard amino acids are so named because these are the only amino acids there are. 2. Essential amino acids can be synthesized by the organism. 3. All standard amino acids are optically active. 4. Overall, naturally occurring amino acids are equally likely to be found having either an R or S configuration around the alpha carbon. O 1, 3, and 4 O 1, 2, 3, and 4 1 and 2 O 1, 2, and 3
Although the first two carbons of fructose and glucose are identical in structure to DHAP and GADP (from glycolysis), DHAP and GADP equilibriate on their in solution to favor the ketone over the aldehyde, while fructose and glucose do not. Why? a)The larger size of the molecule sterically hinders the isomerization b)The larger sugars have more OH groups which hydrogen bond and disrupt isomerization c)The larger sugars cyclize, and there is no carbonyl to isomerize in the cyclic form d)The larger sugars cyclize, and in the cyclic form the hydrogen bonding is very strong e)The larger sugars are less soluble in water than the smaller sugars
