The enzyme unit, or international unit for enzyme (symbol U, sometimes also IU) is a unit of enzyme's catalytic activity. [ 1 ] 1 U (μmol/min) is defined as the amount of the enzyme that catalyzes the conversion of one micro mole of substrate per minute under the specified conditions of the assay method .
Specific activity is equal to the rate of reaction multiplied by the volume of reaction divided by the mass of total protein. The SI unit is katal/kg, but a more practical unit is μmol/(mg*min). Specific activity is a measure of enzyme processivity (the capability of enzyme to be processed), at a specific (usually saturating) substrate ...
The size of a synthesized protein can be measured by the number of amino acids it contains and by its total molecular mass, which is normally reported in units of daltons (synonymous with atomic mass units), or the derivative unit kilodalton (kDa).
Calculate how much protein you need according to your body weight Molloy advises people to eat about 0.75 grams of protein per pound of total body mass, or 1.6 grams per kilogram.
The derived quantity relative molecular mass is the unitless ratio of the mass of a molecule to the atomic mass constant (which is equal to one dalton). [2] The molecular mass and relative molecular mass are distinct from but related to the molar mass. The molar mass is defined as the mass of a given substance divided by the amount of the ...
The average adult should consume at least 0.35 grams of protein per pound of body weight daily to maintain their existing muscle mass and promote overall health, according to the The Academy of ...
The dissociation constant has molar units (M) and corresponds to the ligand concentration [] at which half of the proteins are occupied at equilibrium, [6] i.e., the concentration of ligand at which the concentration of protein with ligand bound [] equals the concentration of protein with no ligand bound []. The smaller the dissociation ...
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 ...
