Front

Ion pair formation in amino acids

Back

A pair of amino acid side chains that can form an ion pair includes oppositely charged side chains, such as Glutamic acid (Glu) and Lysine (Lys).

Front

Phosphatidylserine orientation in membranes

Back

Phosphatidylserine is normally inward facing in the plasma membrane and plays a role in cell signaling.

Front

Effect of double bonds on melting point of unsaturated fatty acids

Back

The melting point of unsaturated fatty acids decreases as the number of double bonds increases.

Front

Characteristics of peptide bonds

Back

Peptide bonds are formed by the condensation of amino acids, exhibit partial double bond character, are planar, but do not have restricted rotation around the bond between the carbonyl carbon and Cα.

Front

Mechanism of statin drugs in lowering cholesterol

Back

Statin drugs lower cholesterol levels by inhibiting the enzyme HMG-CoA reductase, which reduces LDL cholesterol.

Front

Definition of amino acids

Back

Amino acids are organic compounds that serve as the building blocks of proteins, containing an amino group, a carboxyl group, and a side chain (R group).

Front

Role of enzymes in biochemical reactions

Back

Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy required.

Front

Structure of biological membranes

Back

Biological membranes are composed of a phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates, providing fluidity and functionality.

Front

Function of cholesterol in membranes

Back

Cholesterol maintains membrane fluidity and stability, preventing the membrane from becoming too rigid or too fluid.

Front

Definition of saturated vs unsaturated fatty acids

Back

Saturated fatty acids have no double bonds between carbon atoms, while unsaturated fatty acids contain one or more double bonds.
