Summary
Starch metabolism involves diverse enzymes across organisms. This review details structural aspects of key starch-degrading enzymes (glycoside hydrolase families 15, 31, 77) and their use in producing oligosaccharides.
Area of Science:
- Biochemistry
- Enzymology
- Carbohydrate Chemistry
Background:
- Starch, a plant-derived polysaccharide, is a crucial energy source for many organisms.
- Metabolism of starch occurs through hydrolysis pathways in mammals and plants, with unique bacterial pathways involving oligosaccharides.
- Enzymes responsible for starch metabolism exhibit diverse enzymatic properties across different species.
Purpose of the Study:
- To review the structural characteristics of starch-metabolizing enzymes.
- To focus on eukaryotic alpha-glucosidases and bacterial alpha-glucoside-hydrolyzing enzymes.
- To explore the application of these enzymes in oligosaccharide production.
Main Methods:
- Literature review focusing on starch-metabolizing enzymes.
- Analysis of structural aspects of enzymes within glycoside hydrolase families 15, 31, and 77.
- Examination of enzyme applications in oligosaccharide synthesis.
Main Results:

Introduction to Carbohydrates
12.6K
Carbohydrates, proteins, and fats are the primary macronutrients in the human diet. However, carbohydrates are the most favored source of energy in the body. They can be found in a wide variety of foods, including whole grains, fruit, and vegetables, in various forms, such as sugars, starch, and dietary fiber. Based on their structure, carbohydrates are classified into three main classes— monosaccharides, disaccharides, and polysaccharides. The body's cells can only utilize simple...

Enzymes
81.4K
Inside living organisms, enzymes act as catalysts for many biochemical reactions involved in cellular metabolism. The role of enzymes is to reduce the activation energies of biochemical reactions by forming complexes with its substrates. The lowering of activation energies favor an increase in the rates of biochemical reactions.
Enzyme deficiencies can often translate into life-threatening diseases. For example, a genetic abnormality resulting in the deficiency of the enzyme G6PD...

Sugars as Energy Storage Molecules
8.4K
Sugar (a simple carbohydrate) metabolism (chemical reactions) is a classic example of the many cellular processes that use and produce energy. Living things consume sugar as a major energy source because sugar molecules have considerable energy stored within their bonds. Consumed carbohydrates have their origins in photosynthesizing organisms like plants. During photosynthesis, plants use the energy of sunlight to convert carbon dioxide gas into sugar molecules, like glucose. Because this...

Introduction to Enzymes

The use of enzymes by humans dates to 7000 BCE. Humans first used enzymes to ferment sugars and produce alcohol without knowing that this was an enzyme-catalyzed reaction. Wilhelm Kuhne coined the term 'enzyme' in 1877 from the Greek words ‘en’ meaning ‘in’ or ‘within’ and ‘zyme’ meaning ‘yeast.’

Carbohydrate Metabolism
11.0K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Allosteric Proteins-ATCase
5.7K
Binding sites linkages can regulate a protein's function. For example, enzyme activity is often regulated through a feedback mechanism where the end product of the biochemical process serves as an inhibitor.
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis...
