'absorbance' is a correct and usable word in written English.
It is a technical term used in the fields of chemistry and physics to refer to a measure of how well a material absorbs light. For example, "The absorbance of the sample was found to be 0.75."
If the tyrosine or tryptophan content of the protein is known, therefore, the concentration of the protein solution can be determined by measuring its absorbance between 280 and 290 nanometres.
The absorbance of ultraviolet light by tryptophan is greatest, that of tyrosine is less, and that of phenylalanine is least.
Spectrophotometry of protein solutions (the measurement of the degree of absorbance of light by a protein within a specified wavelength) is useful within the range of visible light only with proteins that contain coloured prosthetic groups (the nonprotein components).
For example, the UV-visible spectrum of azulene, a molecule that contains five conjugated π bonds, shows a strong absorbance in the visible region of the electromagnetic spectrum, which correlates with its intense blue colour.
Scientists use a test called the O.R.A.C. (short for oxygen radical absorbance capacity) to rate the antioxidant capacity in foods, and by this measure blueberries always come out on top.
"It was a David Eagleman book called Sum, which is 40 short stories about what the afterlife might be and atomic reincarnation, where you get to heaven and God is presented to you as a bacteria, and of the absorbance of life …" I give him a look that suggests he has lost me.
They are designed to combine strength and shock absorbance with lightness, and that is a genuine achievement.
Xoçai is a product of MXI Corp., a Reno, Nev., company that heavily promotes the chocolate's oxygen radical absorbance capacity, or ORAC.
