Trypsin is a serine protease that specifically recognizes and cleaves peptide bonds on the C-terminal side of positively charged amino acids (Lys and Arg).
Hemoglobin is a globular protein with a compact, spherical structure, unlike fibrous proteins like collagen and keratin.
At isoelectric point, the number of positive charges equals negative charges, resulting in zero net charge and minimum solubility.
Carboxypeptidase is an exopeptidase that removes amino acids sequentially from the C-terminal end of proteins.
Peptide bonds between the carboxyl group of one amino acid and the amino group of the next maintain the primary structure.
Selenocysteine is the 21st amino acid and is not among the standard 20 protein amino acids. It contains selenium instead of sulfur.
