解析 B。原因:文章中明确提到“When we cook, various chemical reactions take place. The heat causes the molecules in the food to break down and combine in different ways.”,即烹饪时是热量导致食物中的分子分解并以不同方式结合。反馈 收藏
Glyca-binding proteins (GBPs)are a category of proteins that bind specifically to certain sugar molecules. The “glyca” is the same prefix you see in the wordglycation. That describes what happens after a protein or fat binds with a sugar molecule (3). This binding process can cause inflamm...
Japanese researchers traced the odor to a chemical compound (化合物) called 2-nonenal. The compound is a byproduct of other chemical breakdowns and sends out a “greasy” or “grassy” odor as the molecules (分子) exit...
Chemistry is all around us in our daily lives. It explains why food cooks, cars run, and plants grow. By studying chemistry, we learn how things work at a microscopic level. From the smallest atoms to large molecules, chemistry helps us understand the building blocks of the world. 💡 Si...
A polymer is made up of very large chains of molecules. The glue used in slime comprises long chains of polyvinyl acetate molecules (that’s why we recommend PVA glue). These chains slide past one another fairly easily, that keeps the glue flowing. Chemical bonds are formed when you mix ...
sustainable partnerships with local producers to support artisanal know-how while merging it with our internal expertise.By combining synthetic molecules and natural ingredients from around the worldwith our in-house technology, we can provide the most comprehensive collection of qualitative, thrilling ...
While you can't mix pee and bleach, there is a way to deal with the situation when your whole house smells like dog urine. There are a lot of commercially available options marketed as enzymatic cleaners. These products contain enzymes, which are biological molecules that break down compounds...
"This is why it's also important to obtain protein from food sources to ensure you are getting all essential amino acids throughout the day", Enright said. Upton suggested opting for a product that contains a minimum of 15 grams of protein per serving. She also strongly encouraged selecting...
You bake with it, sprinkle it over food, and add it to hot drinks. Sugar makes things taste sweeter. But what are the side effects of eating or drinking too much sugar? What is dextrose used for? To improve the flavour of food and drink ...
are then chemically modified — to break bonds between their molecules, for instance — and combined with techniques like extrusion, which forces soft substances together into a desired shape. Colors, flavors, emulsifiers and other additives are also used to enhance a food's taste and shelf life...
