1.) Why is it that amino acids in proteins are called a-amino acids? 2.) explain alpha,...
1. There are a total of amino acids are called natural amino acids that are found in proteins. These according to the older Greek letter nomenclature system for designating carboxylic acid structures. 2. True/ False The alpha carbon is the carbonyl carbon of the carboxylic acid functional group of the amino acid. 3. Which of the following are functional groups in an amino acid? (choose all that apply) a. amine b. amide c. carbonyl d. carboxylic acid e. alcohol f....

All amino acids in proteins are Select one: O a. (R)-amino acids b. chiral c. alpha-amino acid O 0 d. acidic
Proteins are complex biological molecules made of smaller molecules called amino acids. Five common amino acids and their K, values are listed below. Rank them from strongest to weakest acid. Amino acid pka glutamine 2.2 arginine 1.7 threonine 2.5 tryptophan 2.4 proline 2.0
4. In contrast to the alpha amino acids which are ubiquitous in nature, beta amino acids (with an extra carbon in the backbone) are quite rare. They form secondary structures that have very different conformations from traditional proteins. For instance, the compound shown below is the simplest beta amino acid; unusually, it is most stable in a gauche conformation. Draw it and explain why, co, Corn lonic c Hdi athrachan H₂N HT 5. Quebrachitol is a naturally occurring compound found...
Proteins are constructed from relatively few types of small organic molecules called α-amino acids. Answer the following questions about the amino acid valine 1st attempt hi See Periodic Table See Hint Part 1 (1 point) Click on an atom to select it. It will then be highlighted green. Identify the α carbon in the amino acid valine by clicking on the atom Part 2 (1point) See Hint Is the side chain in valine polar, nonpolar, acidic, or basic? Choose one:...
C4. Amino Acids and Proteins Amino acids are organic compounds that contain amine and carboxyl functional groups, along with a side chain specific to each amino acid. Clearly and concisely explain the process of dipeptide formation. [10 Marks) C5. Nucleic Acids Humans have two types of nucleic acids in their bodies: DNA and RNA. These molecules contain the set of instructions for our cells: they determine who and what we are. Compare and contrast DNA and RNA. [10 Marks] C6....
is there a specific sequence of amino acids required for an alpha helix to form. explain why or why not
2. what is the configuration of almost all naturally occurring amino acids at the a (alpha) carbon 3. why is an alpha amino acid such as alanine more acidic than a regular carboxyllic acid 4. strecker synthesis Formation dl-phenylalanine 5. outline the steps to synthesize the simple dipeptide AL (think about two amino acids that begin with an A and an L) 6. give the structure and name of the nucleosides in dna and rna 7. give the structure of...
For the following amino acids - explain why the overall charge on the amino acid is different at PH's 2, 7, and 11. Relate it to the pk, of the groups on the molecules To achieve distinction, you must explain that the form of an amino acid, whether positively charged, negatively charged or neutral, depends on the pH of the solution and also on the Ka of the acid group
