Effects of Light on Secondary Metabolites in Selected Leafy Greens: A Review

Raja and Ramasamy Vijayakumar. Reviewed: June 26th Published: September 5th Secondary Metabolites - Sources and Applications. The metabolism can be defined as the sum of all the biochemical reactions carried out by an organism. Metabolites are the intermediates and products of metabolism and are usually restricted to small molecules.

Maquis species play a central role in the maintenance of coastal ecosystems thanks to anatomical, physiological and biochemical features evolved to cope with severe stress conditions. Because the seasonal and daily dynamics of physiological and biochemical traits of maquis species are not fully addressed, we performed a field study on three coexisting Mediterranean shrubs Pistacia lentiscus L. These species differed in their physiological and biochemical responses especially on a seasonal level. Temperature resulted the most important climatic factor controlling the physiological and biochemical status of these coexisting shrubs and, thus, in determining plant performances in this Mediterranean coastal habitat. Evergreen sclerophylls face drought conditions with a high specific leaf area, thick cuticle and deep root system Karavatas and Manetas, In addition, Mediterranean plants can be also classified as drought avoiding and drought-tolerant species based on their physiology Lo Gullo and Salleo, This is achieved by either restricting water loss from the plant body water saving or by increasing water absorption to replace losses by transpiration water spending Kozlowski and Pallardy,

Primary and secondary metabolites are often used in industrial microbiology for the production of food, amino acids, and antibiotics. Bacterial metabolism can be classified into three major categories: the kind of energy used for growth, the carbon source, and the electron donors used for growth. Pathogenic bacteria are capable of exhibiting various types of metabolism. Metabolites, the intermediates and products of metabolism, are typically characterized by small molecules with various functions. Metabolites can be categorized into both primary and secondary metabolites. These metabolites can be used in industrial microbiology to obtain amino acids, develop vaccines and antibiotics, and isolate chemicals necessary for organic synthesis. Primary metabolites are involved in growth, development, and reproduction of the organism.

Primary and secondary metabolisms are coextensive; they can occur at the same time in the same cell and draw carbon-containing intermediates from the same sources. Generally, though, as nutrients are depleted the rate of growth slows and eventually stops. The progress of metabolism is correspondingly altered and a number of special biochemical mechanisms appear or become amplified to establish what is called secondary metabolism. The resultant secondary metabolites seem to be unnecessary for normal growth of the organism, but rather appear to be aimed at functions such as intercellular communication and defence and competition with other organisms. Secondary metabolism is a common feature of fungi.

Effects of Light on Secondary Metabolites in Selected Leafy Greens: A Review

Secondary metabolites are chemicals produced by plants for which no role has yet been found in growth, photosynthesis, reproduction, or other "primary" functions. These chemicals are extremely diverse; many thousands have been identified in several major classes. Each plant family, genus, and species produces a characteristic mix of these chemicals, and they can sometimes be used as taxonomic characters in classifying plants. Humans use some of these compounds as medicines, flavorings, or recreational drugs.

1. Introduction

Это просто как день. Как они этого сразу не заметили. Северная Дакота - вовсе не отсылка к названию американского штата, это соль, которой он посыпал их раны. Он даже предупредил АНБ, подбросив ключ, что NDAKOTA - он. Это имя так просто превращается в Танкадо. И лучшие в мире специалисты-криптографы этого не поняли, прошли мимо, на что он и рассчитывал.

Их прикосновение было знакомым, но вызывало отвращение. Б нем не чувствовалось грубой силы Грега Хейла, скорее - жестокость отчаяния, внутренняя бездушная решительность. Сьюзан повернулась. Человек, попытавшийся ее удержать, выглядел растерянным и напуганным, такого лица у него она не видела. - Сьюзан, - умоляюще произнес Стратмор, не выпуская ее из рук.  - Я все объясню.

Любые частные лица, которые попытаются создать описанные здесь изделия, рискуют подвергнуться смертоносному облучению и или вызвать самопроизвольный взрыв. - Самопроизвольный взрыв? - ужаснулась Соши.  - Господи Иисусе. - Ищите.  - Над ними склонился Фонтейн.  - Посмотрим, что у них .
