D(+) glucose yields an oxime with hydroxyl amine. The structure of the oxime would be:
1. | 2. | ||
3. | 4. |
1. | D is the acidic amino acid - glutamic acid |
2. | C is an aromatic amino acid - tryptophan |
3. | A is the C-terminal amino acid and D is N terminal amino acid |
4. | A is the sulphur containing amino acid-methionine |
1. | Tissue (X) secretes RNA which changes the development of tissue (Y) |
2. | As tissue (X) develops, it secretes enzymes that inhibit the development of tissue (Y) |
3. | As tissue (X) develops, it secretes something that induces tissue (Y) to develop |
4. | As tissues (X) develops, it secretes something that shows down the growth of tissue (Y) |
