It introduces their basic structural subunits and points out major steps in the biosynthesis and supramolecular processing of fibrillar collagens as prototypical members of this protein family. Collagen’s maps are rather different from those of ball-shaped proteins such as enzymes ; tough packages of collagen called collagen fibres are a major constituent of the extracellular matrix that supports most tissues and gives cells construction from the exterior. Collagen fibers not only make up your skeletal muscle fibers, but they also make up your smooth muscles (such as those in the bladder and reproductive system) and your cardiac (heart) muscles. how does a collagen's structure help its function? 1 Answer. Favorite Answer. Lv 7. A single protein molecule may contain one or more of these protein structure levels and the structure and intricacy of a protein determine its function. Collagen, for example, has a super-coiled helical shape that is long, stringy, strong, and rope-like—collagen is great for providing support. Relevance. Collagen the major structural protein is made up with three parallel strands wound in a right handed fibril. How the structure of DNA is related to its function. The polypeptide strands have a left-handed, polyproline II-type (PPII) helical coil. As DNA is so important, we need it to store lots of information without becoming damaged. As a connective tissue its structure is relatively simple and the peculiar helical arrangement of collagen fibres confers highly non-linear as well as time-dependent mechanical properties. Functional significance cannot be attributed to any facet of mechanical response until the physiological pattern of loading is established. Collagen is besides present in certain cells as it has great tensile strength. 27/03/2013 by sdagar1 Leave a comment. 9 years ago. and is the chief constituent of facia. Its function is to carry oxygen around in the blood, and it is facilitated in doing so by the presence of the haem group which contains a \(\text{Fe}^{2+}\) ion, onto which the oxygen molecules can bind. Collagen fibers provide your muscles with the strength and structure needed to move and function throughout the day. Collagen also provides important functions for your muscles. Each protein strand in the fibril is a left handed helix. There are several ways in which DNA is suited to this role: The sugar-phosphate backbone makes the molecule more stable; DNA coils up into a double helix so that it’s more compact, so lots of … Each of the three chains is a coil itself. According to About.com Biology section, there are three different types of muscle cells, and each has a different structure related to its function. Answer Save. Collagen is a fibrous protein consisting of three polypeptide chains wound around each other. Hemoglobin, on the other hand, is a globular protein that is folded and compact. Type I collagen has always aroused great interest in the field of life-science and bioengineering, thanks to its favorable structural properties and bioactivity. gardengallivant .
