辅酶是一种有机小分子,与酶结合后能增强其催化活性,在生物代谢过程中起关键作用。

用法要点

句型搭配

通常用作可数名词,在句子中作主语或宾语,常与动词如 'act as'、'require' 或 'function as' 搭配使用。

• act as a coenzyme
• require a coenzyme
• function as a coenzyme

介词用法

常用介词 'in' 表示在特定代谢过程中,'for' 表示用于某种反应,'with' 表示与酶结合。

• in cellular respiration
• for energy production
• with an enzyme

语域说明

主要用于生物化学、医学和营养学等学术或专业语境,日常对话中较少使用,除非讨论健康或科学话题。

• in biochemistry textbooks
• in medical research
• in dietary supplements

基础例句

Vitamins often act as coenzymes to help enzymes work better in our bodies.

维生素常作为辅酶,帮助酶在我们体内更有效地工作。

I read that coenzyme Q10 is good for heart health and energy levels.

我读到辅酶Q10对心脏健康和能量水平有益。

Without proper coenzymes, some metabolic processes might slow down.

没有合适的辅酶,一些代谢过程可能会变慢。

高级例句

In biochemistry, coenzyme A is essential for the citric acid cycle, facilitating acetyl group transfer.

在生物化学中,辅酶A对柠檬酸循环至关重要,促进乙酰基的转移。

The research indicates that coenzyme deficiencies can lead to metabolic disorders, requiring targeted supplementation.

研究表明辅酶缺乏可能导致代谢紊乱,需要针对性补充。

Pharmaceutical companies are developing new drugs that modulate coenzyme activity to treat chronic diseases.

制药公司正在开发调节辅酶活性的新药,以治疗慢性疾病。

常见错误

❌ 错误:Coenzyme is same as enzyme.
✓ 正确:A coenzyme is different from an enzyme; it assists enzymes but is not a protein itself.

错误在于将辅酶等同于酶。辅酶是小分子辅助因子,而酶是蛋白质催化剂,两者功能相关但本质不同。

❌ 错误:I need more coenzyme for my diet.
✓ 正确:I need more coenzymes or coenzyme-rich foods in my diet.

错误在于将'coenzyme'用作不可数名词。在指多种或具体辅酶时,通常用复数形式或加修饰语,如'coenzymes'或'coenzyme Q10'。

近义词辨析

cofactor

辅因子是一个更广泛的术语,包括辅酶(有机分子)和金属离子等无机辅助因子,而辅酶特指有机小分子。

Coenzymes are a type of cofactor, but not all cofactors are coenzymes; for instance, magnesium ions are cofactors but not coenzymes.

prosthetic group

辅基是紧密、永久结合到酶上的非蛋白质部分,而辅酶通常松散结合,可在反应中循环使用。

Heme in hemoglobin is a prosthetic group, whereas NAD+ acts as a coenzyme that detaches after catalysis.
