Which amino acids of proteins usually participate in interaction with carbohydrate molecules? Name three of them.
Which amino acids of proteins usually participate in interaction with carbohydrate molecules? Name three of them.
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

In glycoproteins, to what three amino acids are carbohydrate groups most frequently linked? To what functional group is the glycan linked in each case?
er ONE of the following: Name any four (4) non-standard amino acids that occur in proteins.
Proteins are made from chains of amino acids. The amino acids are joined together by structures called peptide bonds. Draw the dipeptide that results when a peptide bond is formed between the two glycine molecules shown here. (Figure 1) Draw it as it would occur at the pHpH of most body fluids. Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default. Include all...
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....
3. The structure and properties of amino acids and the peptide bonds that link them together determine the structure and properties of proteins. Explain how amino acids and peptide properties dictate protein structure and, therefore, their function.
