The R-groups give the aminoacids their physical-chemical characteristics such as polarity (hydrophobic or hydrophilic) and charge (acidic or positive versus basic or negative).
R基团赋予氨基酸物理化学特性,例如极性(亲水性和疏水性)以及电荷(酸性或正电荷,碱性或负电荷)。

The acidicamino acid content of the enzyme was 17.29%, alkaline amino acid 4.50% and neutral amino acid 38.50%, and others were nonpolar amino acids.
In the preparation of aminoacids through acidic hydrolysis of proteins, high concentration of salt is introduced into the hydrolysate when the residual acid is neutralized.
