Do not inculde a header or ID line. There are plenty of plant-based protein options, but they generally contain less protein in a given serving. The molecular weight (mw) of an oligopeptide or a protein can be determined by summation of the mw of its corresponding amino acid sequence. There is nothing wrong with incomplete proteins however, and there are many healthy, high protein foods that are incomplete proteins. 0.8g/kg of body weight is a commonly cited recommended dietary allowance (RDA). NIH, "What are proteins and what do they do? Dietary Protein Requirement of Men >65 Years Old Determined by the Indicator Amino Acid Oxidation Technique Is … Protein Molecular Weight Protein Molecular Weight accepts a protein sequence and calculates the molecular weight. 0.73 cm 3 /g x 10 24 A/cm 3 x molecular weight g/mole-----6.02 x 10 23 molecules/mole and results in a protein volume of approximately: (1.21 x MW) A 3 /molecule This provides a reasonable estimate for general uses. Note: Sequences are treated as sigle-stranded linear DNA with a 5' phosphate. This is used to convert the weight (weight concentration) into the molar quantity (molar concentration) for proteins, and vice versa. No more than 3,000,000 characters are recommended.
