(a) Their complex folded shape allows them to link together (b) Their polar and nonpolar regions allow them to form an amphipathic bilayer (c) Their hydrogen bonds help hold them t Explain why phospholipids are considered amphipathic molecules. What d...
Explain using S and P orbitals how methane is formed. ^1H_1 ^{12}C_6 How do hydrogen atoms make a covalent bond? In chemical compounds, what is meant by the term the valency and the bonding requirements of the individual atoms? How do ions form ionic bonds? How are atoms held togeth...
Bonding interface tilting has been observed to be associated with changes in the number of hydrogen bonds bridging the TCR and pMHC molecules as they were pulled to unbind in SMD simulations6. Therefore, we investigated whether, and if so, how well the tilting angle would correlate with the ch...
Answer to: Explain why hydrogen fluoride (HF) has a higher boiling temperature than hydrogen chloride (HCL) (19.4 o C vs. - 85 o C), even though HF...
Explain how sugars can relate to both the proper sorting of proteins and the functioning of neutrophils. What function do carbohydrates serve in our bodies? Why are lipids, which contain more covalent bonds per ounce than carbohydrates, not used for this function primarily?
Artwork: Top: Natural, latex rubber is easy to pull apart because the long polymer molecules it contains (made from carbon and hydrogen atoms) are only weakly linked together. Bottom: When natural rubber is cooked with sulfur, the sulfur atoms form extra cross-links (shown here as yellow bar...
View Solution (a) What is polygenic inheritance? Explain with the help of a suitable example. (b) How are pleiotropy inheritance different from polygenic pattern of inheritance ? View Solution Explain with the help of suitable example polar covalent bond. ...
Indeed, many important parameters, such as area per lipid, mem- brane thickness (Table S1), free volume in the interface area (Figs. 6 and S5), and number of hydrogen bonds per lipid head (Fig. S9B) are very similar. In other words, despite the dramatic differences in the organization...
In addition, residues from the C-terminal tail engage in van der Waals interactions and three hydrogen bonds with α5 and α6, the N terminus of α7, and the loops connecting these structure elements, in total accounting for almost 20% of the buried surface. The other interface is formed...
Many theories have been suggested to explain how PAHs mix with other carbon molecules to form soot and other carbon nanoparticles. All these studies, however, are insufficient to explain the inception of ‘peri-condensed aromatic hydrocarbons’ with only pi-bonds between carbon atoms, which can be...
