Elastin is a key protein that permits stretching and recoiling after being stretched. It is found in various tissues, including skin, lungs, and blood vessels, allowing these structures to maintain their shape and flexibility. Elastin's unique molecular structure enables it to return to its original form after deformation, contributing to the resilience of elastic tissues in the body.
Pepsin
Titin is part of the A-band of a Sarcomere.
Collagen is the major insoluble fibrous protein in the extracellular matrix and in connective tissue. It’s found in our muscles, bones, skin and tendons. Collagen production naturally begins to slow down as we age. Making wrinkles, sagging skin and weaker cartilage in the joints
Collagen is the substance that gives tendons their strength. It is a fibrous protein that provides structure and support to the tendon, allowing it to withstand tension and resist stretching.
Gluten relaxation is how well their elasticity relaxes with time, usually in wheat flours. It helps the dough retain shape. Protein and gluten strands link together, and resist stretching.
Bone salts (calcium, mainly) lend hardness; the protein-rich organic matrix permits some flexibility
The giant protein titin maintains the organization of sarcomeres in striated muscle cells. Sarcomeres are the basic contractile units of muscle cells and are responsible for muscle contractions. Titin provides structural support and stability to sarcomeres during muscle contraction and relaxation.
Keratin disulfide bonds are strong chemical bonds that link together the protein molecules in hair. These bonds provide strength and structure to hair by forming a network that holds the protein molecules tightly together. This network helps hair maintain its shape and resist damage from stretching or bending.
Western Blots used to diagnose HIV infection detect antibody to a range of HIV proteins. Instead of giving just one answer, they show "positive" or "negative" for each protein on the western blot strip. This makes them very specific for HIV.
The polymer is 'proteine' or better 'polypeptide' (n= big number) and monomer is a 'tetrapeptide' existing of 4 (=tetra) amino acids: -[Gly-Ser-Gly-Ala]n- (lineary coupled, n-times, in this order).(Note the alternating sequence of glycene (Gly) with serine (Ser) and alanine (Ala))The high proportion (50%) of glycine (GLY), which is the smallest amino acid (H2N-CH2COOH), allows tight packing, so the fibers are strong and resistant to stretching. The tensile strength is due to the many interseeded hydrogen bonds.Since the protein forms a 'Beta plated sheet', when stretched the force is applied to these strong bonds and they do not break.
To effectively help sore muscles recover, you can try methods such as rest, gentle stretching, applying ice or heat, getting a massage, staying hydrated, and eating foods rich in nutrients like protein and antioxidants.
Egg protein gives off less protein then meat protein.
