- Please, need help with the explanation and diagram. The structure and properties of poly peptides: A) Describe the type of bonding that would occur when three amino acid monomers (include a diagram of the amino acids) form a tripeptide and describe how such bonds could be formed. B) During the period of Chemical Evolution, what is the significance of the structure of the polymer formed? (Include a diagram)arrow_forwardFind a protein of your choice (rcsb.org), choose a part of it (containing at least 30 amino acid residues), find the amino acid sequence (sequence in it), identify what functional groups the amino acid substitutes contain (carboxyl group and 2-position the Nitro group will form amide bonds, forming the covalent basic structure of the protein). What different interactions can occur between these functional groups? How will it relate to the spatial structure of the protein?arrow_forward01 Description Please draw the structure of the 19 L-a-amino acids and proline in any form, as you prefer. You may want to use a letter-size sheet or larger, it's up to you. Guiding principle: You want to understand the differences among amino acids. Although you may want to only draw the R-group it's preferable to draw it along with the rest of the molecule (i.e., the Ca, the amino group and the carboxyl group). Here are some examples (your drawings should not limited to the following styles): NH₂ OH Alanine H H O OH Proline lysine alarmy stock płwłos Tryptophan OH COOH | H₂N-C-H CH₂ Phenylalanine argininearrow_forward
- Give typing answer with explanation and conclusion On paper draw a dipeptide, clearly showing the peptide bond joining the two amino acids together. If the two amino acids are valine and threonine, predict the overall charge of the dipeptide at pH 7. Do not forget to consider the amino (N-terminal) and carboxy (C-terminal) of the dipeptide, as well as the R groups. Select one: a. +2 b. -2 c. 0 d. -1 e. +1arrow_forwardName and discuss the non-covalent interactions that maintain protein structure. Explain the chirality of amino acid molecules.arrow_forwardProvide the simIlarities and differences of different functional groups of amino acids? Explain thoroughlyarrow_forward
- * Draw the tripeptide FTQ, making sure to care for stereochemistry.* Identify the N-terminus and the C-terminus of the peptide.* Identify what type of stabilizing interactions the amino acid side chains could employ in the tertiary andquaternary structure of a protein.arrow_forwardShow the chemical structure of all 20 amino acids ?arrow_forwardDraw out the basic amino acid structure (not specific) What is a peptide bond?arrow_forward
- Macmillan Learning Consider the structure of methionine in its +1 charge state. H₂N CH₂ CH₂ CH3 -OH Give the pK, value for the a-amino group of methionine. An answer within ±0.5 units is acceptable. Give the pK, value for the a-carboxyl group of methionine. An answer within +0.5 units is acceptable. Determine the isoelectric point (pl) for methionine. Give your answer to two decimal places. pK (−NH ) = pK₂ (-COOH) = pl = 5.74 2.28 Incorrect 9.21 Incorrect Attemptarrow_forwardDraw the structural formula of a simple amino acid.
