Definition. Phytochemicals are chemicals of plant origin. [ 1] Phytochemicals (from Greek phyto, meaning "plant") are chemicals produced by plants through primary or secondary metabolism. [ 2][ 3] They generally have biological activity in the plant host and play a role in plant growth or defense against competitors, pathogens, or predators.
Food chemistry is the study of chemical processes and interactions of all biological and non-biological components of foods. [1] [2] The biological substances include such items as meat, poultry, lettuce, beer, milk as examples. It is similar to biochemistry in its main components such as carbohydrates, lipids, and protein, but it also includes ...
Nutrient. A nutrient is a substance used by an organism to survive, grow and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures such as hair, scales, feathers, or exoskeletons.
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral [ 2] and even weakly acidic properties. [ 3] Some synthetic compounds of similar structure may also be termed alkaloids. [ 4]
Carrots, squash, broccoli, sweet potatoes, tomatoes (which gain their color from the compound lycopene ), kale, mangoes, oranges, seabuckthorn berries, wolfberries (goji), collards, cantaloupe, peaches and apricots are particularly rich sources of beta-carotene, the major provitamin A carotenoid. Vitamin C (ascorbic acid) is a water- soluble ...
There are three principal classes of macronutrients: carbohydrate, protein and fat. [ 1] Macronutrients are defined as a class of chemical compounds which humans consume in relatively large quantities compared to vitamins and minerals which provide humans with energy. Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per ...
An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group –COOH. Sulfonic acids, containing the group –SO 2 OH, are relatively stronger acids. Alcohols, with –OH, can act as acids but they are usually very weak.
