A saturated fat is a type of fat in which the fatty acid chains have all single bonds between the carbon atoms. A fat known as a glyceride is made of two kinds of smaller molecules: a short glycerol backbone and fatty acids that each contain a long linear or branched chain of carbon (C) atoms.
Pentadecylic acid, also known as pentadecanoic acid or C15:0, is an odd-chain saturated fatty acid. Its molecular formula is CH 3 (CH 2) 13 CO 2 H. It is a colorless solid. A laboratory preparation involves permanganate oxidation of 1-hexadecene (CH 3 (CH 2) 13 CH=CH 2). [2] It is one of the most common odd-chain fatty acids, although it is ...
Generally, the epidermal lipid matrix is composed of an equimolar mixture of ceramides (about 50% by weight), cholesterol (25%), and free fatty acids (15%). [39] Saturated fatty acids 16 and 18 carbons in length are the dominant types in the epidermis, [39] [40] while unsaturated fatty acids and saturated fatty acids of various other lengths ...
There are three basic types of freshwater ecosystems: Lentic (slow moving water, including pools, ponds, and lakes), lotic (faster moving water, for example streams and rivers) and wetlands (areas where the soil is saturated or inundated for at least part of the time). Limnology (and its branch freshwater biology) is a study about freshwater ...
The food base of streams within riparian forests is mostly derived from the trees, but wider streams and those that lack a canopy derive the majority of their food base from algae. Anadromous fish are also an important source of nutrients. Environmental threats to rivers include loss of water, dams, chemical pollution and introduced species. [12]
Capric acid, also known as decanoic acid or decylic acid, is a saturated fatty acid, medium-chain fatty acid (MCFA), and carboxylic acid.Its formula is CH 3 (CH 2) 8 COOH. Salts and esters of decanoic acid are called caprates or decanoates.
A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton. The second trophic level (primary consumers) is occupied by zooplankton which feed off the phytoplankton. Higher order consumers complete the web.
