The coagulated protein absorbed some pectin substances mainly through acidicaminoacids by hydrogen bond.
蛋白质凝聚过程还通过酸性氨基酸以氢键结合的方式吸附少量的果胶物质。
2
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.
