steric

Second, the interactions here appear to be entirely steric (that means size/shape related).

Due to the shape of the molecule and steric interactions, the chlorines are very difficult to knock off.

Of course unlabeled nucleotides will outcompete labeled ones, they're smaller so they get less steric hindrance.

They do silly things like predict pretty awful secondary structure, and their predictions can have steric clashes and the like.

It analyzes steric/electronic properties of your molecule and ranks compatible reaction templates with optimized conditions.

You're going from a primary amine to a secondary amine, one with a moderately steric hindrance on it (considering that the amine is the focal point of the polypeptide production reactions).

I believe there has been research taking these sorts of molecule imprinted polymers beyond strictly steric interactions.

For instance, not factoring in steric factors (e.g.

Remember, we are talking about overall steric and electrostatics here.

One of the advantages of natural antibodies is that they can bind their targets via H-bonding, ionic interactions, van der Waals interactions, and hydrophobic interactions in addition to steric interactions.

And it doesn't get absorbed because it doesn't react with sucrase (or invertase), maybe because the big chlorine atoms bumping around there result in steric hindrance that keeps it from binding to the enzyme properly.

There was a community I discovered a few years ago deliberately trying to up their saturated fat intake (specifically steric acid) and on it's own it's about as pleasurable as chewing on a candlestick (steric acid is used as a stiffener in paraffin candles).

Its called steric interference, which is a fancy way of saying "something is in the way".

Intercalators typically have 300-500 daltons worth in a "planar greasy brick" regime, with very little in the way of bulky or floppy steric groups.

Also to quote the wikipedia article, "Chaperones do not necessarily convey steric information required for proteins to fold: thus statements of the form `chaperones fold proteins` can be misleading."

This is assuming there is some mechanism by which you can "scan" the DNA, which in itself has a whole host of steric/timing issues (different chromatin states, how do you deal with cell division?
