a) Inside; they repel water; Secondary
b) Outside; they attract water; Tertiary
c) Inside; they attract water; Quaternary
d) Outside; they repel water; Secondary

Answer 1

Acidic amino acids like aspartate and glutamate are found on the outside of proteins due to their water-attracting properties and play a significant role in the tertiary structure through ionic and hydrogen bonding.

Step-by-step explanation:

Acidic amino acids, such as aspartate and glutamate, are typically found on the outside of proteins and enzymes because they are polar and attract water. This characteristic makes them more likely to be located on the protein surface, where they can interact with the aqueous environment. Acidic amino acids can participate in important types of bonding, such as ionic bonding through electrostatic attractions between oppositely charged side chains, and hydrogen bonding, which is crucial in both intra- and intermolecular interactions of proteins. Furthermore, these amino acids play a significant role in the tertiary structure of proteins, as their interactions contribute to the overall three-dimensional folding and stability.
