WebWikipedia: Carbohydrate; The Chemistry of Health: Sugars and Fats; Collagen: Connective Tissue. Collagen literally holds us together. Collagen is a relatively simple protein, made of three separate chains of amino acids that twist together. Just as strong rope is made of small strands twisted together, collagen is strong, yet flexible. Carbohydrates are polyhydroxy aldehydes, ketones, alcohols, acids, their simple derivatives and their polymers having linkages of the acetal type. They may be classified according to their degree of polymerization, and may be divided initially into three principal groups, namely sugars, oligosaccharides and … See more In organic chemistry, a carbohydrate is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water) and thus with the empirical formula Cm(H2O)n … See more Formerly the name "carbohydrate" was used in chemistry for any compound with the formula Cm (H2O)n.

The failure to effectively use these molecules accounts for the majority of the inborn errors of human carbohydrates metabolism.
Carbohydrates are typically stored as long polymers of glucose molecules with glycosidic bonds for structural support (e.g. chitin, cellulose) or for energy storage (e.g. glycogen, starch). However, the strong affinity of most carbohydrates for water makes storage of large quantities of carbohydrates inefficient due to the large molecular weight of the solvated water-carbohydrate complex. In most organisms, excess carbohydrates are regularly catabolised to form acetyl-CoA, which is a feed s… WebSacharidy. Sacharidy (z lat. saccharum = cukr ), též glycidy, zastarale uhlovodany, uhlohydráty nebo karbohydráty, jsou organické sloučeniny patřící do skupiny polyhydroxyderivátů karbonylových sloučenin ( aldehydů nebo ketonů ).
