The phrase "aliphatic group" is correct and usable in written English.
It is typically used in the context of chemistry to refer to a group of organic compounds that do not contain aromatic rings and are characterized by straight or branched chains of carbon atoms.
Example: "The aliphatic group in this molecule contributes to its hydrophobic properties."
Alternatives: "alkane group" or "open-chain group".
Among the aliphatic group are the unsaturated polyesters, a class of resins that are molded into fibreglass-reinforced structures such as pleasure-boat hulls.
Surface ligands generally have an amphiphilic structure consisting of a polar head group and a nonpolar aliphatic group.
In our knowledge, it is the first time where fibrous cellulose is enzymatically acylated by a long chain aliphatic group in one step, without the necessity of any pretreatment.
The spectrum reveals that the carbonyl group (C = O, 1635 cm−1) and –OH stretching and the aliphatic group (–C H stretching of 3465 and 2,088 cm−1), are involved in the reduction of Ag+ to Ag.
A weak peak at 2,923 cm−1 was ascribed to aliphatic group stretching vibration, and according to Huang et al. (2012) the low intensity of this peak is due to the decrease in aliphaticity in the activated carbon by increasing temperature.
Furthermore, peaks at 1450 1650 cm−1 were assigned to benzene ring and (C=C) moiety and those at 1522 1590 cm−1 were attributed to (C O) stretching [16] while peaks for aliphatic group were seen at 2900 2940 cm−1.
Amines are also classified as aliphatic, having only aliphatic groups attached, or aromatic, having one or more aryl groups attached.
Single arrows indicate aliphatic groups.
The weak -CH2, -CH3 bands suggest that the aliphatic groups associated with the deposits are negligible.
Moreover, it can be concluded that aliphatic groups get collapsed at high temperature.
The spectra show peaks at 2935/1460 and 2850/1370 cm−1 which correspond to CH3 and CH2 aliphatic groups.
