Abstract:
Jasmonates, including (+)-7-iso-jasmonic acid and related compounds, are plant hormones that regulate both developmental and defense responses. Among jasmonates, 12-hydroxyjasmonates, such as 12-hydroxyjasmonic acid (12-OH-JA) and 12-hydroxyjasmonoyl-l-isoleucine (12-OH-JA-Ile), are commonly observed in various plant species. 12-Hydroxyjasmonates regulate jasmonate responses, both dependent and independent of CORONATINE-INSENSIVE 1 and JASMONATE ZIM-DOMAIN proteins, which are the most studied jasmonate co-receptors. This review summarizes the existence, biosynthesis, metabolism, bioactivities, and biological functions of 12-hydroxyjasmonates.

Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...

Overview of Fatty Acid Metabolism
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...
Types of Hormones
Steroids and eicosanoids fall under the category of lipid-soluble hormones. Steroids are derived from cholesterol and feature four interconnected carbon rings with variable side chains. Notable examples include estradiol from ovaries and testosterone from testes, exemplifying the critical roles of these lipid-soluble hormones in reproductive physiology. Eicosanoids, derived...
