Sunflower seed The sunflower seed is the fruit of the sunflower ("Helianthus annuus"). There are three types of commonly used sunflower seeds: linoleic (most common), high oleic, and NuSun developed for sunflower oil. Each variety has its own unique levels of monounsaturated, saturated, and polyunsaturated fats. The information in this article refers mainly to the linoleic variety.

Linoleic acid Linoleic acid (LA), a carboxylic acid, is a polyunsaturated omega-6 fatty acid, an 18-carbon chain with two double bonds in cis configuration. A shorthand notation like "18:2 (n-6)" or "18:2 "cis"-9,12" may be used in literature. It occurs in nature as a triglyceride ester, free fatty acids are typically low in foods.

Propiolic acid Propiolic acid is the organic compound with the formula HCCOH. It is the simplest acetylenic carboxylic acid. It is a colourless liquid that crystallises to give silky crystals. Near its boiling point, it decomposes. It is soluble in water and possesses an odor like that of acetic acid.

Carvone Carvone is a member of a family of chemicals called terpenoids. Carvone is found naturally in many essential oils, but is most abundant in the oils from seeds of caraway ("Carum carvi"), spearmint ("Mentha spicata"), and dill.

Sulfonic acid A sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula R−S(=O)−OH, where R is an organic alkyl or aryl group and the S(=O)−OH group a sulfonyl hydroxide. A sulfonic acid can be thought of as sulfuric acid with one hydroxyl group replaced by an organic substituent. The parent compound (with the organic substituent replaced by hydrogen) is the hypothetical compound sulfurous acid. Salts or esters of sulfonic acids are called sulfonates.

Homocitric acid Homocitric acid is an organic compound with the formula HOC(COH)(CHCOH)(CHCOH). This tricarboxylic acid occurs naturally as a component of the iron-molybdenum cofactor of certain nitrogenase proteins. Biochemists often refer to this cofactor as homocitrate, which is the conjugate bases that predominate in neutral aqueous solutions of this species.

Naphthazarin Naphthazarin, often called 5,8-dihydroxy-1,4-naphthoquinone or 5,8-dihydroxy-1,4-naphthalenedione (IUPAC), is a naturally occurring organic compound with formula C10H6O4 , formally derived from 1,4-naphthoquinone through replacement of two hydrogen atoms by hydroxyl (OH) groups. It is thus one of many dihydroxynaphthoquinone structural isomers.

Glutamic acid Glutamic acid is an α-amino acid with formula C5H9O4N . It is usually abbreviated as Glu or E in biochemistry. Its molecular structure could be idealized as HOOC-CH(NH2 )-(CH2 )-COOH, with two carboxyl groups -COOH and one amino group -NH2 . However, in the solid state and mildly acid water solutions, the molecule assumes an electrically neutral zwitterion structure OOC-CH(NH3+ )-(CH2 )-COOH.

Acetic anhydride Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CHCO)O. Commonly abbreviated AcO, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis. It is a colorless liquid that smells strongly of acetic acid, which is formed by its reaction with moisture in the air.

Helianthus annuus Helianthus annuus, the common sunflower, is a large annual forb of the genus "Helianthus" grown as a crop for its edible oil and edible fruits (sunflower seeds). This sunflower species is also used as bird food, as livestock forage (as a meal or a silage plant), and in some industrial applications. The plant was first domesticated in the Americas. Wild "Helianthus annuus" is a widely branched annual plant with many flower heads. The domestic sunflower, however, often possesses only a single large inflorescence (flower head) atop an unbranched stem. The name "sunflower" may derive from the flower's head's shape, which resembles the sun, or from the impression that the blooming plant appears to slowly turn its flower towards the sun as the latter moves across the sky on a daily basis.

Selinene Selinenes are a group of closely related isomeric chemical compounds which are classified as sesquiterpenes. The selinenes all have the molecular formula CH and they have been isolated from a variety of plant sources. α-Selinene and β-selinene are the most common and are two of the principal components of the oil from celery seeds. γ-Selinene and δ-selinene are less common.

Asterids In the APG IV system (2016) for the classification of flowering plants, the name asterids denotes a clade (a monophyletic group). Common examples include the forget-me-nots, nightshades (including potatoes, eggplants, tomatoes, peppers and tobacco), the common sunflower, petunias, morning glory and sweet potato, coffee, lavender, lilac, olive, jasmine, honeysuckle, ash tree, teak, snapdragon, sesame, psyllium, garden sage, and table herbs such as mint, basil, and rosemary.

Caprylic acid Caprylic acid is the common name for the eight-carbon saturated fatty acid known by the systematic name octanoic acid. Its compounds are found naturally in the milk of various mammals, and as a minor constituent of coconut oil and palm kernel oil. It is an oily liquid that is minimally soluble in water with a slightly unpleasant rancid-like smell and taste.

Hydnocarpic acid Hydnocarpic acid is an unsaturated fatty acid. It differs from most fatty acids by having a cyclic ring system at the terminus, rather than being entirely straight chain. It is found in the oil from plants of the genus "Hydnocarpus" from which it derives its name.

Xanthophyll Xanthophylls (originally phylloxanthins) are yellow pigments that occur widely in nature and form one of two major divisions of the carotenoid group; the other division is formed by the carotenes. The name is from Greek "xanthos" (ξανθός, "yellow") and "phyllon" (φύλλον, "leaf"), due to their formation of the yellow band seen in early chromatography of leaf pigments.

Cultivar group A cultivar group – represented in a botanical name by the symbol Group or Gp (previously cultivar-group) – is a formal category for cultivated plants that share a defined characteristic according to the "International Code of Nomenclature for Cultivated Plants" ("ICNCP"). "Group" or "Gp" is always written with a capital "G" in a botanical name, or "epithet". The cultivar group is not italicized in a plant's name. The "ICNCP" introduced the symbol "Group" in 2004, as a replacement for the lengthy and hyphenated "cultivar-group", which had previously been the category's name since 1995. The non-standard abbreviation cv. group is also sometimes encountered.
