Dietary Carbohydrates Classification Biochemistry And Physiology
Dietary carbohydrate characterization should reflect relevant nutritional and functional attributes and be measured as chemically identified components.
Dietary carbohydrates classification biochemistry and physiology. Introduction properties classification and biological significance carbohydrates are polyhydroxy aldehydes or ketones. It should be noted that only the retrograded amylose type of rs the dominating type in processed foods is included in the present aoac dietary fibre methods classification of dietary carbohydrates totid cm h7 ab by wince 1 f. In deciding how to classify dietary carbohydrate the principal problem is to reconcile the various chemical divisions of carbohydrate with that which reflects physiology and health. Carbohydrates biochemistry of carbohydrates.
This in the words of the editor s preface is a complete revision and expansion in scope of chemistry of the carbohydrates published 10 years ago and reviewed in abst. They are commonly known as sugars because most of them have a sweet taste. A classification based purely on chemistry does not allow a ready translation into nutritional terms since each of the major classes of carbohydrate have a variety. For food labelling carbohydrates have to be divided into a number of nutritionally meaningful classes.
In the classification of carbohydrates as saccharides glucose is a while starch is a homopolysaccharide and consists of repeating units of glucose molecules. Food databases should include as much specific and detailed information as possible on food carbohydrates. Carbohydrates all coming from the process of photosynthesis represent the major part of organic substance on earth are the most abundant organic components in the major part of fruits vegetables legumes and cereal grains carry out many functions in all living organisms and are the major energy source in a mediterranean type diet. The passage of a decade is in respect of any branch of science bound to lead to considerable additional knowledge and the subject of carbohydrate chemistry seems in no way to have lagged.
Classification carbohydrates are also classified as reducing and non reducing sugars. The following points highlight the top three classifications of carbohydrates. A first classification should then aim at differentiating the digestible and undigestible carbohydrates i e. Carbohydrates are the most abundant bio macro molecules on the earth.
It is a minor classification.
