adding methacryloyl groups. GelMA retains the similar properties of gelatin and ECM components and is temperature sensitive and shear thinning. During the 3D printing process, as the temperature decreases, the number of triple helix structures and hydrogen bonds in the hot GelMA solution increases, an...
A carbonyl functional group consists of a carbon atom which is double-bonded with an oxygen atom. The general structure of an amide is given as {eq}{\rm{R}}\left( {{\rm{C = O}}} \right){\rm{N}}{{\rm{R}}_1}{{\rm{R}}_2} {/eq}, where R, {eq}{{\rm{R}}_1,}\;...
Replacement of the hydrogen atoms of an ammonia molecule by hydrocarbon groups gives amines. The carbonyl group consists of a carbon atom and an oxygen atom joined by a covalent double bond. An aldehyde, RCHO, is a compound in which a hydrogen atom and a hydrocarbon group are bonded to a...
The hydroxyl functional groups (shown in Table 6.2) that exist in water consist of a hydrogen atom and an oxygen atom bonded together. It is the dominant reactive surface functional group for clay minerals, amorphous silicate minerals, metal oxides, oxyhydroxides, and hydroxides (Sposito, 1989)...

Esters have a pair of alkyl or aromatic groups attached to a carbonyl + linking oxygen function. Esters can be shown in text as: RCOOR or (occasionally) ROCOR. carboxylic acid + alcohol -> ester + water This is an acid catalysed equilibrium. Amide Primary amides (shown) have an alkyl or...
Alkenyl and carboxamide groups receive more attention due to the higher bond energy of the carbon–carbon double bond and the stability of the amide bond, requiring more energy to break them apart into separate atoms. The interpretability exploration illustrates how functional prompts bridge the gap ...

31). Thus, the zwitterionic phospholipid headgroups (PC, PE) combined with monounsaturated tails cause the stabilization of non-functional open states. If the anionic headgroup PG is combined with the PO tails, we observed a semi-stabilization of non-functional open states (SoPIP2;1 in one ...
