Essay

Following are approximate values of the Amex Gold BUGS Index. $\begin{array} { | l | l | l | l | } \hline \text { Year } \boldsymbol { x } & 0 & 2 & 4 \\\hline \text { Index } \boldsymbol { y } & 50 & 100 & 250 \\\hline\end{array}$ ​
( $x = 0$ represents 2000)
Complete the table. $$\begin{array} { | l | l | l | l | l | } \hline & x & y & x y & x ^ { 2 } \\\hline & 0 & 50 & & \\\hline & 2 & 100 & & \\\hline & 4 & 250 & & \\\hline \text { Totals } & & & & \\\hline\end{array}$$ ​

Definitions:

α-Helix

A common structural motif in proteins, characterized by a right-handed coiled configuration of the polypeptide chain.

Secondary Structure

The local folded structures that form within a polypeptide due to interactions between atoms in the backbone.

Globular Protein

Proteins that are roughly spherical in shape, often soluble in water and serving roles in catalysis, regulation, and transport.

Aspartic Acid

A non-essential amino acid involved in the synthesis of proteins and in the urea cycle of mammals.
