STRUCTURA’s collagen has a stated molecular weight of 4,000 Daltons. Here is how to read that number alongside the rest of the formula.
A unit of molecular mass
A Dalton, abbreviated Da, is a unit scientists use for molecular mass. Four thousand Daltons is also written as 4 kDa. This measurement is different from the grams of collagen in a serving.
From protein chains to peptides
Hydrolysis breaks long collagen protein chains into smaller fragments called peptides. A hydrolysed ingredient contains a distribution of peptide sizes, rather than millions of identical fragments.
A single stated molecular-weight figure does not describe that entire distribution or identify how it was measured.
Inside STRUCTURA
STRUCTURA provides 10g hydrolysed marine collagen peptides per serving. Its collagen is derived from the skin of non-endangered, farmed fish and has a stated molecular weight of 4,000 Daltons. The source and molecular-weight details apply specifically to STRUCTURA.
What the number does not establish
Molecular weight can be relevant to the properties of an ingredient, but a Dalton number alone does not prove superior absorption or a particular health outcome. Processing, peptide composition and the finished formula all matter.
