Endothermic reactions, on the other hand, absorb heat and/or light from their surroundings. For example, decomposition reactions are usually endothermic. In endothermic reactions, the products have more enthalpy than the reactants. Thus, an endothermic reaction is said to have a positive<span> enthalpy of reaction. This means that the energy required to break the bonds in the reactants is more than the energy released when new bonds form in the products; in other words, the reaction requires energy to proceed</span>

What would be the interactions between side chains of aspartate and arginine at a neutral ph?
weeeeeb [17]

The answer is asparagine interactions between aspartate and arginine side chains at neutral pH

<h3>What side chain does arginine have?</h3>
  • The amino acid arginine has the formula (H2N)(HN)CN(H)(CH2)3CH(NH2)CO2H.
  • A guanidino group is attached to a typical amino acid framework in the molecule.
  • The carboxylic acid is deprotonated (CO2) and both the amino and guanidino groups are protonated, resulting in a cation at physiological pH.
  •  The guanidine group in arginine is the precursor for nitric oxide production. it is a white, water-soluble solid, like all amino acids.
