how to i draw this following lipid at PH 7.4. N-palmitoyl-D-erythro-sphingosylphosphorylcholine (aka16:0 sphingomyelin). thank you!

BSC1010C Enzymes & Cellular Regulation Dr. Harris 4. Compare the rate of the pepsin-catalyzed reaction at pH = 1.5 with the rate of the lipase- catalyzed reaction at pH = 1.5. 5. Compare the rate of the pepsin-catalyzed reaction at pH = 8.0 with the rate of the lipase- catalyzed reaction at pH = 8.0. 6. Based on your understanding of protein structure, explain in detail the effect of exposing an enzyme to a pH outside its optimal range. Include a discussion of the effect on both the structure and function of the enzyme. 7. At what pH values is lipase likely to be denatured? Explain your answer.

9 Insulin can be best described by which statements? Select the correct response(s): It is made up of 2 peptide chains with a total of 3 alpha helices, 2 beta sheets, and 3 disulfide bridges. It is synthesized by the beta cells of the pancreas and released into the bloodstream to stimulate assimilation of glucose by the cells. It is made up of 2 peptide chains with a total of 3 alpha helices, 2 beta sheets, and 2 disulfide bridges. It is synthesized by the beta cells of the pancreas and released into the bloodstream to stimulate secretion of glucose by the cells. It is synthesized by the beta cells of the pancreas and released into the bloodstream to stimulate synthesis of glucose by the cells.

Test for Monosaccharides:  Clinistix Carbohydrate molecules range from the very simple to the very complex. The word “saccharide” means sugar, while the prefixes “mono”, “di” and “poly” categorize carbohydrates according to how many simple sugar molecules are joined together to form the carbohydrate.   To test for the presence of monosaccharide, we will be using Clinistix (a product that is used to test for the presence of glucose in urine).  See the label (in video) for details.  These test strips are used by dipping the colored end into the solution, then comparing the color to the chart on the bottle.  The positive color(s) is/are __________________________.  The negative color is ________________.   Test for Starch (a Polysaccharide):  Povidone Iodide Test Plant cells manufacture glucose molecules during photosynthesis and store them in large starch molecules.  Because starch is a long chain of many glucose units all joined together, it is a polysaccharide. Povidone Iodide (which…

Hi, please help with this question: What is the net charge on the amino acid cysteine at pH 8.0? (pKa values are α-carboxyl 2; α-amino 10; side chain 8) Thanks

TRUE OR FALSE 1. In the structure of Aztreonam, addition of a moiety capable of Van de Waals interaction confers stability against beta-lactamases 2. Addition of an acyl amino group to carbapenems increases their resistance to acid degradation, thus, making them stable in an oral dosage form 3. In the core structure of monobactams, the methyl group cannot be rotated because of its attachment on the beta lactam ring. The structure is too rigid for the methyl group to be rotated

Some terms will not be used. The prosthetic group of hemoglobin and myoglobin is The organic ring component of heme is Under normal conditions, the central atom of heme is In the central iron atom is displaced 0.4 Å out of the plane of the porphyrin ring system. The central atom has bonds: to nitrogen atoms in the porphyrin, one to a residue, and one to oxygen.
