Which component of amino acids accounts for the differences in their properties?
The Alkyl group (R) is a component of amino acids accounts for the differences in their properties.
An amino acid contains an Amino group, Carboxyl group, H atom and an Alkyl group. Amino group, Carboxyl group and H atom are common for all amino acids. Alkyl group(R) is unique for every Amino acid. It differs from an amino acid to other amino acid.
This provides unique property to every protein structure as well since amino acids make a polymer of proteins. The alkyl group in amino acid can be Carbon containing, Ring containing, Amino group or a carboxyl group as well.
If an amino group is added in place of an alkyl group or with an alkyl group then the amino acid becomes basic in nature.

The tendency to maintain a stable, relatively constant internal environment is called homeostasis.
Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment.
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.
In contrast, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.
The concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose. If these values get too high or low, person might end up getting very sick.

Why is it important to maintain the ph of blood and tissue fluids within normal limits?
It is important to maintain the ph of blood and tissue fluids within normal limits because the structure and function of macromolecules are pH sensitive, and even little variations from normal pH can cause metabolic processes to shut down.
Tissue fluid is found in the spaces around cells. It comes from substances that leak out of blood capillaries (the smallest type of blood vessel). It helps bring oxygen and nutrients to cells and to remove waste products from them.
The two forms of connective tissue in this subcategory are blood and lymph. Both are fluid rather than solid, and neither has the network of extracellular protein fibers that other types of connective tissue have.
Diffusion and filtration processes create tissue fluid from plasma. This fluid fills the intracellular space and serves as a link in the transmission of nourishment, gases, and metabolic end products between blood capillaries, tissue fluid, and lymph.
