Lactose is a disaccharide found in animal milk. It consists of a molecule of D-galactose and a molecule of D-glucose bonded by beta-1-4 glycosidic linkage.. A carbohydrate (/ ˌ k ɑːr b oʊ ˈ h aɪ d r eɪ t /) 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 C m ...
Carbohydrate metabolism is the whole of the biochemical processes responsible for the metabolic formation, breakdown, and interconversion of carbohydrates in living organisms. Carbohydrates are central to many essential metabolic pathways . [ 1 ]
According to Oxford English Dictionary the specific term glycobiology was coined in 1988 by Prof. Raymond Dwek to recognize the coming together of the traditional disciplines of carbohydrate chemistry and biochemistry. [3] This coming together was as a result of a much greater understanding of the cellular and molecular biology of glycans.
In molecular biology and biochemistry, glycoconjugates are the classification family for carbohydrates – referred to as glycans – which are covalently linked with chemical species such as proteins, peptides, lipids, and other compounds. [1] Glycoconjugates are formed in processes termed glycosylation.
Biochemistry, or biological chemistry, is the study of chemical processes within and relating to living organisms. [1] A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology, and metabolism. Over the last decades of the 20th century, biochemistry has become successful at ...
In biochemistry, a metabolic pathway is a linked series of chemical reactions occurring within a cell.The reactants, products, and intermediates of an enzymatic reaction are known as metabolites, which are modified by a sequence of chemical reactions catalyzed by enzymes.
Oligosaccharides are carbohydrates that consist of a polymer that contains three to ten monosaccharides linked together by glycosidic bonds. Glucose reacts with oxygen in the following reaction, C 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H 2 O. Carbon dioxide and water are waste products, and the overall reaction is exothermic .
Carbohydrase is the name of a set of enzymes that catalyze five types of reactions, turning carbohydrates into simple sugars, from the large family of glycosidases. [1] Carbohydrases are produced in the pancreas, salivary glands and small intestine, breaking down polysaccharides.
