Draw clearly and fully the structure of the amino acids in the order of: cysteine, histidine, asparagine, and glycine. Clearly label the R groups and the N / C terminus and finally name the peptide chain.
Note: Make sure all double bonds and nitrogens face the same direction and show stereochemistry

Draw the following peptide tyrosine-cysteine-lysine-leucine. Identify the functional groups of the side chains by name and label the peptide bonds, the N-terminus, and the C-terminus of the peptide. Also, what is the one letter code? Draw the membrane lipid phosphatidylserine with stearic acid and oleic acid attached to the glycerol-3-phosphate backbone in position 1 and 2, respectively. How are the individual parts of the molecule (glycerol, phosphate, serine, and fatty acids) connected to each other?

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. +1

Protein Structure A protein contains a string of amino acids (usually more than 50) that has a biological function. 15ecause proteins are so large, their structure has several levels, all of which are important for the proper functioning of the protein. Ultimately, the sequence of amino acids (ordering of polar and nonpolar amino acids) dictates the 3-dimensional shape of a protein and this dictates its primary function. Level 1: Primary (1") The amino acid sequence of a polypeptide Protein Backbone...
