5 天之前 · A lipid is any of various organic compounds that are insoluble in water. They include fats, waxes, oils, hormones, and certain components of and function as energy-storage molecules and chemical messengers. Together with proteins carbohydrates, lipids are one of the principal structural components of living . Why are lipids important?
Wax - Chemistry LibreTexts
A wax is a simple lipid which is an ester of a long-chain alcohol and a fatty acid. The alcohol may contain from 12-32 carbon atoms. Waxes are found in nature as coatings on leaves and stems. The wax prevents the plant from losing excessive amounts of water.
27.1 Waxes, Fats, and Oils - Organic Chemistry - OpenStax
Animal fats and vegetable oils are the most widely occurring lipids. Although they appear different—animal fats like butter and lard are solids, whereas vegetable oils like corn and peanut oil are liquid—their structures are closely related.
3.4: Waxes - Chemistry LibreTexts
2021年5月11日 · Waxes are esters of fatty acids with long chain monohydric alcohols (one hydroxyl group). Natural waxes are often mixtures of such esters, and may also contain hydrocarbons. Plant waxes on the surfaces of leaves, stems, flowers, and fruits protect the plant from dehydration and invasion by harmful microorganisms.
Waxes - LIPID MAPS
Biochemists often link waxes with the thin layer of fatty constituents that cover the leaves of plants or provide a surface coating for insects or the skin of animals for which the primary requirements are hydrophobicity, spreadability, and chemical and metabolic stability.

2019年11月12日 · Waxes Definition: Waxes are the organic compounds composed of lipophilic compounds and malleable solids. Waxes form the protective coating by the mixture of long-chain apolar lipids. In plants, wax forms a protective coat of cutin on plants, leaves, and fruits. Waxes Structure Defined Below. There are two types of waxes: True Waxes.
