Among these molecules, harbingers of life, there are amino acids, the base of all proteins found in every living creature. Also in these droplets there are sugars, essential for the construction of DNA.在这些孕育生命的分子中有氨基酸，它是每种生物体内所有蛋白质的基础。在这些液滴中还有糖，它对...
Which one of these is incorrectly matched with its description? A. Triglyceride - the most common form of lipids B. Polypeptide - long chains of amino acids that form proteins C. Starch - a carbohydrate that plants use to store glucose D. Unsaturated fat ...
Arginine is sometimes also considered an essential amino acid, but only children need it, not adults. Plants can make all of the essential amino acids. Benefits of amino acids What foods contain amino acids? You get amino acids from proteins, which are in meats, grains, and some dairy produ...
Closely fitting, brick-shaped plant cells have a rigid outer layer that helps provide the structural support that trees and other plants require. Long, tapered muscle cells have an intrinsic stretchiness that allows them to change length within contracting and relaxing biceps. Still, as different...
Studies have shown that the consumption of CA-rich foods leads to a protective effect against carcinogenesis by preventing the formation of nitro compounds (nitrosamines and nitrosamides) that are the main inducers of this pathology. The anti-carcinogenic action of CA is mainly associated with its ...
Different plants are also sources of asparagine. In addition to asparagus, the acid is found in some root vegetables, such as potatoes. Whole grains such aswheatandoatsare also excellent sources of the compound, as are some types of legumes and soy. Various types of nuts also contain Asn. ...
Plants have evolved a defence mechanism (stomatal closure) to reduce bacterial entry through stomata by detection of pathogen-associated molecular patterns (PAMPs). To defeat stomatal defence, P. syringae uses toxins and T3SS effector proteins to overcome PAMP-induced stomatal closure. Stomatal closure...
Humans have 20 different amino acids that are used to produce all the proteins the body needs. Biologists suggest there are at least 10,000 different types of proteins, but there may be as many as several billion species. The amino acids are linked together first intopolypeptide chains, which...
What amino acids have phosphorus in them? What are complement proteins? What do complement proteins do? What macromolecule is produced during translation? What molecule remains in the nucleus during protein synthesis? Which structure is the site of the synthesis of proteins that may be exported from...
Glutamic acid is a nonessential amino acid that's found in meats, dairy products, and certain plants. The role of glutamic acid in...
