Describe the interactions between amino acids that contribute to form the secondary structure of a protein. What are some of the basic configurations that result? Which of the following groups varies among different amino acids? a. hydrogen atom b. carboxyl group c, R g...
Cell walls of microalgae and cyanobacteria are composed of polysaccharides and carbohydrates that have negatively-charged (amino, carboxyl, hydroxyl or sulfide) groups. Most metals are bound to the negatively-charged ligand groups, which is the basis for metal removal from wastewaters. Beside this ...
What category does the amino acid Cysteine, that has the R group -CH_2-SH, belong to? A) Acidic B) Basic C) Polar D) Non-polar E) Hydrophobic What macromolecules use glycosidic linkage? a. proteins b. lipids c. carbohydrates d. nucleic acids ...
Is nitro group acidic or basic? Acidiccharacter: Due to the strong electron withdrawing nature of the nitro group (-I effect) the α-hydrogen bonded to the carbon atom bearing the nitro group is acidic, which can easily be abstracted by a base. ...
Phosphorylation of the carboxyl group of one of these carbamates would then be followed by cyclization and loss of Pi. A more detailed mechanistic picture of this enzymatic reaction has been provided by subsequent investigations. Gibson et al.12 and Huang et al.13 have shown that solutions of ...
chemically similar since all are made up of many amino acid units linked together in a long chain. Amino acids are the building blocks from which all proteins are made. as their name implies, amino acids are difunctional; they contain both a basic amino group and an acidic carboxyl group. ...
(1994). Acidic carboxyl-terminal domain of gene 2.5 protein of bacteriophage T7 is essential for protein-protein interactions. J Biol Chem 269:5270-5278.Kim, Y.T., and Richardson, C.C. (1994). Acidic carboxyl-terminal domain of gene 2.5 protein of bacteriophage T7 is essential for ...
Are proteins acidic or basic? Proteins usually are almost neutral molecules; that is, they haveneither acidic nor basic properties. This means that the acidic carboxyl ( ―COO−) groups of aspartic and glutamic acid are about equal in number to the amino acids with basic side chains. ...
Why are carboxyl groups considered acidic? Explain why the pH of 1.0M hydrochloric acid is 1.0M while that of 1.0M ethanoic acid is 5.0. Explain why the pH decreases when SO_3 is dissolved in water. An acid, HA, is 90% unionized. Is this a strong or weak acid? Explain. ...
