The phrase "acids of about" is correct and usable in written English.
It can be used when discussing the approximate concentration or quantity of acids in a scientific or technical context.
Example: "The solution contained acids of about 0.5 molarity, which is suitable for the experiment."
Alternatives: "acids approximately" or "acids roughly".
The ancestor sequence is generated as a random Bernoulli amino acid sequence of about 200 a.a., probabilities of selection of amino acids were taken as advised in [ 19].
In the case of temperature structuring alone an increase of the methacolein and methacrylic acid yield of about three points has been verified experimentally.
Other FAR transcripts are homologous to the fatty acyl-CoA reductase from a wide range of insect species including H. virescens, N. vitripennis, Danaus plexippus, Bombus terrestris and Apis mellifera with amino acid identities of about 60% (Table 3).
VP6 has an amino acids sequence identity of about 20% with the σ2 protein of MRV species (Table 2).
Importantly, all fusion proteins were constructed with an identical five amino acids linker region of about 20 angstroms long (see Methods).
Similarly, each paratope has about 15 amino acids of which about five contribute to the binding energy for the epitope.
The experiments showed that the most immunogenic domain of the NS3 protein was the fourth designed fragment (F4), a 122 amino-acid (AA) region of about 13.5 kDa (nucleotide 1003 1368; residue 335 456).
The stochastic process of indel accumulation reaches saturation at an amino acid identity level of about 15% (Pascarella and Argos 1992).
One of those encodes an efflux pump homologous to the characterized PmpM MATE efflux pump from Pseudomonas aeruginosa with translated amino acid sequence identity of about 40% over 99% of the protein sequence.
Under normal conditions, the human omnivorous diet generates a net gain of acid of about 1 mmol H+/kg body weight/day, such that there is little need for renal bicarbonate-excretory function.
