Amides are less reactive than are esters due to the fact that nitrogen is more willing to donate its electrons than is oxygen. As a result, the partial positive
genes do not contain all the information needed to make proteins. They only specify a one-dimensional protein chain; the three-dimensional structure that the proteins take, which is vital for their function, is determined by the cellular...
We always learnt (from GCSE bond enthalpies) that "Bigger bonds are stronger", so to speak; my teacher often quoted N≡NN≡N as very unreactive as the triple bond is very strong. However, now we are covering organic chemistry in a bit more depth at A-level,...
Unengaging characters might be: Too passive. They’re sitting back and letting life happen to them – rather than doing anything to fight for what they want and need. While characters may be stuck inreactivemode in the first half of a novel, you don’t want characters who just sit around...
Motilin stimulates peristalsis in the stomach and small intestine motility, causing undigested food to move into the colon. This, in turn, stimulates the urge to defecate (poop). Any new mother has seen the gastrocolic reflex in action. This is why infants often need their diapers changed so...
I don't think it is useful to categorize this to suggest all atoms should have a given ratio or that the ratio should exceed some value. I find it sufficient to understand that the non-bonded electrons of oxygen and nitrogen can interfere with nucleophilic attack, but those of a chlorine ...
L-histidine (HIS) is an essential amino acid with unique roles in proton buffering, metal ion chelation, scavenging of reactive oxygen and nitrogen species, erythropoiesis, and the histaminergic system. Is histidine essential for adults? Rose's later work showed that eight amino acids are essential...

In addition, nitrogen dioxide stands out as a very reactive pollutant generated mostly through the combustion of fossil fuels, with traffic pollution being the primary source (He et al 2020a, 2020b). It is linked to a 6.94% rise in daily COVID-19 confirmed case numbers in 120 Chinese ...
