Amino acids.
Amino acids group together to form proteins. Enzymes are protein in nature. Thus the substrate is an amino acid.

Chemical Properties of Nonmetals
:
- Nonmetals are poor conductors of heat and electricity. ...
- Unlike metals, nonmetals aren't malleable and ductile.
- Nonmetals react more with metals than with nonmetals.
- Usually, nonmetals react with other nonmetals in high temperature.
- Most nonmetals do not react with air in room temperature.
The cooling effect meaning that your skin releases alcohol molecules with the appropriate heat for it to evaporate. The alcohol is cold on your skin for the reason that when it comes in contact, the temperature of the body makes it change from fluid to gas, which pulls warm from the encompassing condition, including the skin. The aftereffect of this response is a chilly feeling.
Full Question:
Although it is not really a chemical reaction, one could consider a cooling process to be analogous to the enthalpy change that occurs in a reaction. Consider the transformation
Fe (s, T = 300 K) → Fe (s, T = 250 K)
If the specific heat of iron is 0.449 J/g·K, what is the enthalpy change of this process for 100 g of Fe (s)? Is the process endothermic or exothermic? Explain.
Answer:
ΔH = - 2245J
Explanation:
Specific heat capacity, Cp = 0.449 J/g·K
ΔH=MCpΔT
ΔT = 250K - 300K = - 50K
ΔH = 100 * 0.449 * (-50)
ΔH = - 2245J
The iron will lose (give off) heat energy to cool down. Hence, it is an exothermic process. The negative sign of the enthalpy confirms this.
