Which amino acids could be referred to as derivatives of butanoic acid? Give their structures. Draw the amino acid in zwitterion form. Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate structures with + signs from the drop-down menu

Researchers discover a new amino acid. Its R-group exclusively has hydrogen and carbon atoms. What behavior will this amino acid show? O Relative to the amino acids found in organisms, its interactions with water will be very high. It is hydrophilic. Relative to the amino acids found in organisms, its interactions with water will be intermediate. It is hydrophobic.

Identify the part of a generic amino acid that reacts with base and the part that reacts with acid. Briefly explain your answer.Hint: Draw Lewis structures for ammonia (NH 3) and acetic acid (CH 3COOH).

Highlight each peptide bond in the molecule below. In addition, list the common names of the smaller molecules that would be released if all the peptide bonds were hydrolyzed. You can add more rows to the table if you need to. (Note: you do not need to list water.) If there are no peptide bonds in the molecule, just check the no peptide bonds box below the drawing area.

Explain why casein precipitates when vinegar is added. Why was milk or raw egg once used as an antidote in cases of heavy metal poisoning? Based on your isolated yield of casein, how many grams of the protein are in one 200 g glass of milk? Which of the solutions contained amide bonds? Which test tells you this? Which of the solutions contained compounds with primary amino groups? Which test tells you this? Describe two examples of protein folding patterns and identify what level of protein structure they belong to. What other reagents might you use besides ferric chloride to test affinity for metal ions?

at a pH value of 2, the amino and carboxyl groups in an amino acid will exist as

On the basis of polarity, what are the four types of side chains found in the standard amino acids? Draw one of the standard amino acids as an example and indicate the types of side chains
