【正文】 這些食品就像是在家庭里一樣準(zhǔn)備制作的，然后分析其中殺蟲劑、工業(yè)化合物、重金屬、放射性核素、重要的礦物質(zhì)的實(shí)際水平。23. Chemicals in our food supply e from six sources. They are industrial accidents, intentional fraud, natural pounds, food additives, pesticides, and environmental pollutants. All require a different concept of food safety a different approach.在我們食品供應(yīng)的化學(xué)物質(zhì)來源于六個(gè)方面，他們是工業(yè)事件，認(rèn)為欺騙，自然化合物，食品添加劑，農(nóng)藥以及環(huán)境污染物質(zhì)。18. However, how can we determine the exact requirement for nutrients for each individual since we are all different? The answer is that the exact requirement cannot be calculated。我們需要這些營(yíng)養(yǎng)素提供能量、建造和維持身體組織、調(diào)節(jié)生理反應(yīng)，這就是食品必須營(yíng)養(yǎng)素在身體中的三大功能。s active site (lockandkey model) or because the enzyme39。換句話說，催化劑不會(huì)改變反應(yīng)物與產(chǎn)品之間的能量平衡，只是降低反應(yīng)物與產(chǎn)品之間的能量差值。這些天然存在的分子可以通過采用非極性有機(jī)溶劑萃取的方法，在細(xì)胞和組織中分離得到。長(zhǎng)鏈羧酸通常由偶數(shù)個(gè)（16~36個(gè)）C原子組成，而長(zhǎng)鏈醇也是由偶數(shù)個(gè)（24~36個(gè)）C原子組成。9. In such instances, the enzyme without the cofactor is called an apoenzyme, and the apoenzymecofactor plex is called a holoenzyme. We will see that the protein chain of an apoenzyme can have functional groups on its side chains (R groups) which are important to its catalytic function, but other important functional groups are introduced by way of cofactors.有些時(shí)候，不含輔基的酶叫脫輔基蛋白酶，輔基和脫輔基蛋白酶的復(fù)合物叫全酶。12. As constituents of food we eat they not only provide energy but also provide a basis for tastes, color, texture, keeping qualities, and overall acceptability of that food, not nutrients, and therefore should consider the total role of nutritional pounds in food.作為我們所吃食物的組分，它們不僅提供了能量，而且提供了該食物的味覺、顏色、質(zhì)地、質(zhì)量保持和總的接受程度。16. Each of these nutrients contains carbon, hydrogen, and oxygen, while protein also contains nitrogen and it is the ratio of carbon to hydrogen to oxygen that determines the number of calories they provide. 這些營(yíng)養(yǎng)素含有C、H、O，蛋白質(zhì)還含有N，并且C、H、O的比例決定了他們提供能量的大小。21. Using the RDA as standards for evaluating the adequacy of nutrient intakes is like setting the standard for height 7 feet and assuming that all of those under7 feet have suffered growth retardation.運(yùn)用RDA作為衡量營(yíng)養(yǎng)素是否充足的標(biāo)準(zhǔn)就像給身高為7英尺的人設(shè)定標(biāo)準(zhǔn)，并且假定那些低于7英
