Concept introduction:
Many amino acids are linked together through amide bonds to form a biologically large molecule known to be proteins.
Amino
Zwitter ion has both positive as well as negative charge, thus it is also called neutral dipolar ion.
Zwitter ion accepts proton in acidic condition and in basic condition zwitter ion lose electrons.
Isoelectric point are the

- how does the sphingosine affect the physical properties of sphingomyelin?arrow_forwardD- and L- designations are used to distinguish between the two possible enantiomers of the monosaccharide, galactose. From the Fischer projection, determine the designation of this monosaccharide.arrow_forwardDoes gentiobiose (Problem 20.66) have an acetal grouping? A hemiacetal grouping? Do you expect gentiobiose to be a reducing or nonreducing sugar? How would you classify the linkage (x or β and carbon numbers) between the two monosaccharides?arrow_forward
- Following are Fischer projections for a groupof five-carbon sugars, all of which are aldopentoses. Identify thepairs that are enantiomers and the pairs that are epimers. (Thesugars shown here are not all of the possible five-carbon sugars.)arrow_forwardWhat is the structure of a simple triaclyglycerol from compound J and Harrow_forwardFollowing are Fischer projections for a group of five-carbon sugars, all of which are aldopentoses. Identify the pairs that are enantiomers and the pairs that are epimers. (The sugars shown here are not all of the possible five-carbon )arrow_forward
- Spermaceti, a fragrant substance isolated from sperm whales, was commonly used in cosmetics until it was banned in 1976 to protect the whales from extinction. Chemically, spermaceti is cetyl palmitate, the ester of palmiticacid with cetyl alcohol (the straight-chain 16-carbon alcohol). Draw the structure of spermaceti.arrow_forwardDraw the structure of Pro-Leu-Glu at physiological pH (7.4).arrow_forwardGiven the monosaccharide: what is its main functional group (aldose or ketose?)Is it triose, hexose, pentose or tetrose?is it D or L configuration?arrow_forward
- 1. Draw the condensed structural formulas for A and B. [0] [0] CH, CH, CH-CH, C-OH А B 2. Identify the type of glycosidic bond that links the monosaccharides and the structure of the disaccharide as a- or 8-isomer. CH-OH H. H OH H. CH, HO OH H. H. ОН Н OH HO H. OH A,arrow_forwardGlutathione is a commonly occurring tripeptide; it has considerable physiological importance because it is a scavenger for oxidizing agents. gamma-glutamyl-L-cysteinylglycine. Draw the structure of Glutathione and explain why the systematic name of Glutathione is such.arrow_forwardWhat is unusual about glutathione’s structure? (If you cannot answer this question, draw the structure you would expect for the tripeptide and compare your structure with the actual structure.)arrow_forward
