Phenylketonuria (PKU): What is PKU and its Treatment

In the United States, each year about 1 in 10,000 to 15,000 babies is born with PKU. This disease occurs in all ethnic groups. But it is most common in Native Americans and northern Europeans in African Americans, or Japanese in Ashkenazi Jews. What causes PKU? PKU is inherited. That means it is passed from parents to children […]

What is Zwitter Ion and Isoelectric point

Amino acids have at lease two ionizable groups, i.e., -COOH and -NH2+, of which the former dissociates more easily than the latter. at physiological pH (7.3), the carboxyl group exists in ionized form whereas the amino group remains undissociated and thus retains a positive charge. This doubly charged molecule of amino acid containing a negative […]

Physio Chemical Properties of Amino acids? (Guide)

Amino acids are basically building blocks of proteins. This chapter includes the Physio chemical properties of Amino acids. Before going to the properties of amino acids, we should brush back the amino acids basic points. What is an Amino acids? Amino acids are biological organic molecules containing both an amino group(s) and a carboxyl groups(s). […]

Titration Curve of Glycine : The zwitter ionic changes

Glycine is optically inactive, simplest amino acid because which have no asymmetric carbon atom. Acid-Base titration involves the gradual addition (or) removal of protons. It has three different stages when the Glycine undergoes acid-base titration. What is Amino acid and its Structural Chemistry? Color reactions of Amino acids What is Zwitter Ion and Isoelectric point […]
