carboxyl

The two viruses use their spikes’ S1 subunit carboxyl-terminal domains (S1-CTD) for high-affinity and species-specific ACE2 binding.

It is composed of two amino acids, with a carboxyl group converted to a methyl ester.

That proton is missing from the carboxyl group resulting in a carboxylate group (COO-).

This -A form, called the acid form, has a carboxyl group attached to it which changes how the cannabinoids interact with your body.

Fatty acids are not hydrocarbons as they all contain a carboxyl group.

The carboxyl groups are comparatively strong acids, the amino groups are comparatively strong bases, so there is a proton transferred to NH2, making it NH3+.

Being a dicarboxylic acid—here the simplest, just two carboxyl groups bolted together—it's reasonably strong, stronger than say acetic acid but mild enough that it doesn't suffer the drawbacks of the easily-available inorganic acids.

Normally the lipid bilayer is in a liquid phase but the the switching out of monovalent sodium for bivalent calcium ions changes the number of phospholipid carboxyl head groups each ion is electrostatically associated with.

Our vaccine formulation is composed of a FEN-like hapten containing a linker with a carboxyl moiety suitable for carbodiimide coupling chemistry to form amide bonds to lysine residues on the carrier protein CRM197, a genetically deactivated diphtheria toxin contained in several FDA-approved conjugate vaccines.

"Decarboxylation" or the removal of a carboxyl group, where it's usually released as CO2, is a common reaction in chemistry, and it doesn't tend to require a lot of activation energy.

Analyzing N-terminal and C-terminal of the polypeptide chain Peptide chain end group amino acids are divided into two classes: amino-terminal and Carboxyl-terminal.
