酯zhǐ(zhi3)

酯 (zhǐ) refers to an organic compound known as an ester, which is formed from the reaction of an alcohol and an acid.

Cultural note

In Chinese cuisine, esters contribute to the scents of various food items like fruits and fermented products, making them significant in food flavoring and preservation. Understanding esters helps appreciate the complexity of traditional Chinese cooking.

Memory tip

Imagine a sweet, fruity aroma wafting from a bottle of perfume, which is made from esters. The character 酯 consists of the radical for 'liquid' (氵) and 'fat' (脂), reminding you that esters often come from fats or oils. The pronunciation 'zhǐ' can sound like 'girth', making you think of how these compounds can add 'girth' to flavors and scents.

AI study notes for 酯

Usage Notes

酯 is used primarily in scientific and technical contexts, particularly in chemistry and industry. Learners often confuse it with similar-sounding words; ensure you distinguish it from '脂' (fat) and '醇' (alcohol). Use it in formal contexts when discussing organic chemistry or related topics.

HSK Study Tips

酯 is not part of the HSK vocabulary lists, making it more specialized. However, it connects with other chemistry-related terms such as '酸' (acid) and '醇' (alcohol), which are more common. Focus on understanding its role in organic chemistry to better grasp its usage.

Common Mistakes

Learners often confuse 酯 with 脂, mistakenly using 脂 when discussing esters. For example, saying '脂的香味' (the fragrance of fat) instead of '酯的香味' (the fragrance of esters) can lead to misunderstandings.

酯 functions as a noun — it names a person, place, thing, or concept. Place it as a subject before the verb (主+谓) or as an object after the verb (谓+宾).
