Titin Titin is the third most abundant protein in muscle (after myosin and actin), and an adult human contains approximately 0.5 kg of titin. With its length of ~27,000 to ~33,000 amino acids (depending on the splice isoform), titin is the largest known protein.

Biotin Biotin, also known as vitamin H or coenzyme R, is a water-soluble B-vitamin (vitamin B7). It is composed of a ureido (tetrahydroimidizalone) ring fused with a tetrahydrothiophene ring. A valeric acid substituent is attached to one of the carbon atoms of the tetrahydrothiophene ring.iotin is necessary for cell growth, the production of fatty acids, and the metabolism of fats and amino acids. Biotin assists in various metabolic reactions involving the transfer of carbon dioxide. It may also be helpful in maintaining a steady blood sugar level.

What Is Biotin (Appearex)? Biotin is a form of vitamin B, present in many foods and available as a supplement. Biotin is sold under many names, including Appearex, vitamin B7, vitamin H, biotina, biotine, and coenzyme R. Many multivitamins and B-vitamin supplements also contain biotin.: Biotin is an essential water-soluble B vitamin. It is a supplement that is used for a variety of reasons including skin, nails and heart health. The U.S. Recommended Dietary Allowance (RDA) for biotin is 300 micrograms daily. This is the dose used in many dietary supplements.

Chapter 5: Macromolecules It is formed of glucose monomers and found in liver and muscle cells. It is hydrolyzed when fuel is needed. Chitin is a polysaccharide similar to cellulose except that it has a nitrogenous appendage on each glucose monomer. It is actually leathery but becomes hardened when encrusted with calcium carbonate.
