Summary Introduction
To review:
The series of reactions thatshow the role of pyridoxal phosphate in the reaction of alanine and α-ketoglutarate.
Introduction:
Transamination can be characterized by the transfer of α-amino groups from α-amino acid to α-keto acid. This reaction is catalyzed by aminotransferase enzyme, which is also called transaminase. In this reaction, the keto acid acts as the acceptor while the amino acid acts as the donor of amino group. This results in the formation of a new amino acid and a new keto acid. Such reactions require a coenzyme called PLP (pyridoxal-5’-phosphate). This enzyme is derived from a vitamin B6, pyridoxine.

Question 1.
a) Explain how 5 specific fatty acids ultimately generate specific classes of prostaglandins and leukotrienes that are involved in blood pressure, platelet aggregation and inflammation.b) Indicate and explain the specific effects of each of these classes of prostaglandins and leukotrienes on blood pressure, platelet aggregation and inflammation.c) Identify which foods, functional foods and nutraceuticals provide one or more of these 5 fatty acids.
Four important properties of enzymes are high catalytic rate,high degree of substrate specificity, negligible formation ofside products, and _____________________.
The hexokinases are a class of enzymes that catalyze the ATP-dependent phosphorylation of hexoses (sugars with six carbons). The hexokinases will bind only D-hexose sugars and not their L-counterparts. In general terms, describe the features of enzyme structure that make this specificity possible.
