一般描述

All collagen molecules are composed of three peptide chains arranged in a triple helix conformation, and their primary structure is mainly composed of three amino acids as repeating motifs, with every two amino acids being a glycine residue. The first two positions are usually proline or 4-hydroxyproline
Type I collagen differs from other collagens in its low lysine hydroxylation and low carbohydrate composition
Col1a1 (collagen, type I, alpha 1) or collagen is a major human structural protein that aggregates in the form of fibers
This is a very long and thin protein, and the most abundant protein found in the human body
It is composed of three left-handed polypeptides
The supercoiled right-handed helix structure composed of chains consists of~1040 amino acids, which are essentially repeating sequences of three amino acids - (Gly-X-Y) n. Gly is glycine, X is Y can be any amino acid, but in the human body, it is usually proline and hydroxyproline, respectively
Product is clear to hazy colorless solution with a few insolubles at 1 mg/ml in water with 2 μl acetic acid (or 0.1 N acetic acid). The insolubles can be removed by settling or centrifugation. 应用
