1)蛋白质一级结构(Primary structure)是组成蛋白质多肽链的线性氨基酸序列 (amino acid sequences)。 2)蛋白质二级结构(Secondary structure) 则是依靠不同氨基酸之间的C=O和N-H基团间的氢键(hydrogen bonds)形成的稳定结构。最常见的二级结构是α螺旋(α helix)和β折叠(β pleated sheet)。 3)蛋白质三级结构(...
Ⅱ Samples of A-LEVEL biology examination for analyzing 1 describe the structure of RNA and DNA and explain the importance of base pairing and the different hydrogen bonding between bases; the structure of DNA and RNA DNA RNA Stand Double strands ...
Most proteins fold into 3D structures that determine how they function and orchestrate the biological processes of the cell. Recent developments in computational methods for protein structure predictions have reached the accuracy of experimentally determined models. Although this has been independently verifie...
To facilitate analysis of RNA caps, we developed a systems-level mass spectrometry-based technique, CapQuant, for accurate and sensitive quantification of the cap epitranscriptome. The protocol includes the addition of stable isotope-labeled cap nucleotides (CNs) to RNA, enzymatic hydrolysis of ...
The expression level of ORAI2 mRNA was higher in classical and mesenchymal types as described in a certain study [94]. ORAI2 has a prominent role in epithelial mesenchymal transition in both types of GBM and was found to correlate with self-regenerating features of stem cells. SOCE compound...
Thellungiella halophila (also known as T. salsuginea) is a model halophyte with a small size, short life cycle, and small genome. Thellungiella genes exhibit a high degree of sequence identity with Arabidopsis genes (90% at the cDNA level). We previously
At present, the attention has been drawn to the fundamental understanding of the behavior of food macromolecules to interpret bioactivities at the molecular level. In this contribution, an overview of the main interactions between phenolics and proteins in foods including their effects on biological ...
