Conformational energy computations were carried out on collagenlike triple-stranded conformations of several poly(tripeptide)s with the general structure CH3CO(GlyXY)3NHCH3. The sequences considered had various amino acid residues in position X or Y of the central tripeptide, with either Pro or ...
The body’s need for amino acids depends on our age, nutritional and health status. Collagen peptides such as Peptan has a specific amino acid composition that is beneficial to our health...
THE composition of collagen is known to vary between species and between different tissue sources of the same animal 1 . The amino-acid hydroxyproline is a characteristic amino-acid of collagen since it is found, to a limited extent, in only one other protein, elastin. The hydroxyproline co...
amino acid n. Any of various compounds containing an amino group (NH2), a carboxylic acid group (COOH), and a distinctive side chain, especially any of the 20 amino acids that link together to form proteins. Some amino acids (called nonessential) can be synthesized in the human body, whi...

This hypothesis is of substantial importance, as the glycine residues in collagen constitute nearly 10% of the amino acid residues in humans. To test this hypothesis, we synthesized a series of collagen mimic peptides that contain one or more d-alanine or d-serine residues replacing the ...
The amino acid sequence of alpha1-CB3, a peptide containing 149 residues obtained from the central portion of the alpha1(I) chain of chick skin collagen by cyanogen bromide cleavage, has been determined. As in the other sequences from the helical region of collagen chains, the repeating trip...
Amino-acid Composition and Thermal Stability of the Skin Collagen of the Antarctic Ice-fish 来自 Semantic Scholar 喜欢 0 阅读量: 157 作者:RIGBY,B. J 摘要: THE various families of fish (for example, Chaenichthyidae, Nototheniidae, Zoarcidae) in the order Perciformes—found exclusively in the...
The unique structure of praline (and its hydoxylated derivative, hydroxyproline) causes this amino acid to play a unique role 17、in protein structure.The amino acids with positively charged (basic) r groups at ph 6-7 are lysine; argiine has a positively charged quanidino group. At ph...
