In a peptide bond, which atoms are involved in bond formation?
Carbonyl carbon and amino nitrogen
Which end of a protein is typically more likely to have positively charged amino acids?
Left end (N-terminus)
How are the physical and chemical properties of proteins determined?
By the number and sequence of amino acids present
How is the size of a polypeptide typically expressed?
In terms of molecular weight (Daltons or kilodaltons)
What is the primary factor that determines the physical and chemical properties of a protein?
The specific sequence of amino acids present in the polypeptide chain
Which statement about the peptide bond is true?
The peptide bond is a single bond with partial double bond character, preventing free rotation
