The molecular masses of proteins, nucleic acids, and other large polymers are often expressed with the unit kilodalton (kDa) ... 0.999 999 999 65 (30) g/mol: 3.0 ...
In mammals, GAD exists in two isoforms with molecular weights of 67 and 65 kDa (GAD 67 and GAD 65), which are encoded by two different genes on different chromosomes (GAD1 and GAD2 genes, chromosomes 2 and 10 in humans, respectively).
For example, water has a molar mass of 18.0153(3) g/mol, but individual water molecules have molecular masses which range between 18.010 564 6863(15) Da (1 H 2 16 O) and 22.027 7364(9) Da (2 H 2 18 O). Atomic and molecular masses are usually reported in daltons, which is defined in terms of the mass of the isotope 12 C (carbon-12).
The molecular mass (for molecular compounds) and formula mass (for non-molecular compounds, such as ionic salts) are commonly used as synonyms of molar mass, differing only in units (daltons vs g/mol); however, the most authoritative sources define it differently. The difference is that molecular mass is the mass of one specific particle or ...
The mole and the atomic mass unit (dalton) were originally defined in the International System of Units (SI) in such a way that the constant was exactly 1 g/mol, which made the numerical value of the molar mass of a substance, in grams per mole, equal to the average mass of its constituent particles (atoms, molecules, or formula units) relative ...
L-selectin varies between cell types, has ranging molecular weight from 65 kDa in lymphocytes to 100 kDa in neutrophils, and is due to cell type-specific glycosylation. Most glycoproteins undergo either N- or O-linked glycosylation, and it is very likely that the type of L-selectin glycosylation determines the specific functions of individual ...
Ingredients. 1 burger bun. 1/3 oz butter. 7 oz fresh ground Wagyu beef, formed into a patty. 3 slices fresh tomato. 2 pieces of Gem lettuce. 3 sweet pickles, sliced
Protein G is an immunoglobulin-binding protein expressed in group C and G streptococcal bacteria much like protein A but with differing binding specificities. It is a ~60-kDA (65 kDA for strain G148 and 58 kDa for strain C40) [1] cell surface protein that has found application in purifying antibodies through its binding to the Fab and Fc region.
