Dietary carbohydrates come in many forms, but ultimately, all carbohydrates are produced by: a. plants b. animals c. microbial life d. oceanic anomalies Where do consumers get their energy from? Where are phytochemicals found in carbs, fats, proteins, and fibers?
Using a method they developed to watch moment to moment as they move a molecule to precise sites inside live human cells, Johns Hopkins scientists are closer to understanding why and how a protein at one location may signal division and growth, and the same protein at another location, death...
Cellulose microfibrils aresynthesized at the cell surface by rosette structures known as the CSC. Each CSC is composed of six rosette subunits, and each subunit contains several catalytically active cellulose synthase proteins (CESAs) that synthesize cellulose chains (Figure 3(a)). What are microf...
J Carstens - 《Nature Medicine》 被引量: 2发表: 2016年 Moving beyond static snapshots: Protein dynamics and the Protein Data Bank Proteins are the molecular machines of living systems. Their dynamics are an intrinsic part of their evolutionary selection in carrying out their biologica... MD Mill...
A growing number of biological processes have been found to be regulated by the covalent attachment of the ubiquitin-like protein SUMO to key cellular targets. A critical step in the process of analyzing the role of SUMO in regulating the activity of these proteins is the identification of the...
What is osmosis and which role does it play in nature? What is meant by "electron carrier?" Where are radula found? What is the role of the collecting duct? What is an amniotomy, and what important nursing roles go along with it? What is the Allee effect? Why is it...
Some examples of cells using exocytosis include:the secretion of proteins like enzymes, peptide hormones and antibodies from different cells, the flipping of the plasma membrane, the placement of integral membrane proteins(IMPs) or proteins that are attached biologically to the cell, and the recycling...
Liquid-ordered assemblies in biomembranes, known as lipid rafts, are small and transient but can coalesce and become stabilized during signalling and vesicle budding. How proteins contribute to phase separation and preferentially distribute into one of the two different phases (or at their interface) ...
aonly in the 1930s was his controversial widely accepted , after John Northrop and Moses Kunitz crystallized pepsin,trypsin,and other digestive enzymes and found them also to be proteins 只在30年代是他有争议宽接受,在约翰Northrop和Moses Kunitz被结晶的蛋白酵素、胰蛋白和其他消化酶以后和也发现他们是...
What state are polar molecules are found in? Why is it important that the nasal cavity warms the air that is passing into the body? Explain wave function. What is gas liquid chromatography? And how is it done? Describe the importance of light in the process of photosyn...
