Most polypeptides are rather large. They contain at least 50 -2000 amino acids.
Most natural polypeptide chains contain between 50 and 2000 amino acid residues and are commonly referred to as proteins.
Most polypeptides are rather large. They contain at least __________ amino acids.
Number of amino acids in between each turn of an a-helix? The backbone polypeptides in a parallel b-sheet run the and the backbone polypeptides in an antiparallel b-sheet run the direction direction In both an a-helix and b-sheet, the interactions are accomplished by these two functional groups on the amino acids: Q7: Protein Kinase/Protein Phosphatase Both kinases and Phosphatases involve the transfer of this: Most kinases use this molecule (listed in part a) as a donor.

The synthesis of protein or polypeptides from individual amino acids would seem to cause a decrease in entropy and require some sort of energy input. How is the energy supplied for protein synthesis?
Amino acids are least soluble at isoelectric point. Does this mean amino acids with Isoelectric point near pH of physiological fluids likely to crystallize in tissue?

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....
Why do the pKa values of ionizable groups differ between free amino acids and amino acid residues in polypeptides? thanks
The genetic code is considered degenerate because most amino acids are encoded by at least two different codons. Some researchers have hypothesized that during evolution the genetic code has been optimized for its intended use in different organisms. Reseachers can study this by examining the relationship between the frequency with which an amino acid appears in all the proteins in an organism and the total number of codons for an amino acid. An optimized organism would use amino acids in...
