解析 B。本题考查细胞膜的主要成分。选项 A“Protein”蛋白质在细胞膜中有重要作用,但不是主要成分;选项 B“Lipid”脂质是细胞膜的主要成分;选项 C“Carbohydrate”碳水化合物在细胞膜上起识别等作用,并非主要成分;选项 D“Nucleic acid”核酸主要存在于细胞核和细胞质中,不是细胞膜的主要成分。
The amino acid chain of an integral membrane protein can pass through the cell membrane once, or weave in and out of the cell membrane multiple times. They contain non-polar side chains, which allow them to interact with the fatty acid chains of the phospholipids. This interaction holds the...
Integral membrane proteinscontain large hydrophobic domains embedded in cell membranes which are essential to supporting proteins' correct fold and function. A rapidly developing structural method of solid-state NMR offers a unique advantage over other structural methods in that it can be applied to ...
Protein functions in the cell, such as enzymatic activity, signaling, and transport, are driven by conformational changes between multiple states1,2,3. To understand biological processes at the molecular level, we therefore require a precise description of protein dynamics1. Pump-probe time-resolved...
Entry of enveloped viruses relies on insertion of hydrophobic residues of the viral fusion protein into the host cell membrane. However, the intermediate conformations during fusion remain unknown. Here, we address the fusion mechanism of Rift Valley fev

And previously mapped touch receptors float free in the cell membrane, responding only when their particular patch of the cell's surface changes shape. The new structural data show how NOMPC's spring-like tethers might tie it to the cytoskeleton, potentially enabling the receptor to sense distant...
We and others have observed that in naïve, non-injured, rodent brains endogenous MANF protein expression is primarily localized in neurons. However, mRNA levels are relatively high in all brain cell types. Endogenous MANF is localized in the endoplasmic reticulum (ER) lumen but can also be ...
