In solid modeling and computer-aided design, boundary representationâoften abbreviated as B-rep or BREPâis a method for representing shapes using the limits. A solid is represented as a collection of connected surface elements, the boundary between solid and non-solid.
0.07-0.88 mmol/L. The Nonesterified Fatty Acids (Free Fatty Acids) assay is useful in evaluating lipolysis and fatty acid oxidation. Nonesterified Fatty Acids may be useful in evaluating patients with hypoglycemia and for nutritional assessment.
Lipids could be fats, oils, sterols, some vitamins, and waxes (long chained alcohols). One example of a lipid that is a free fatty acid is the polyunsaturated fat Linoleic acid, and omega-6 fatty acid with a chemical formula of C18H32O2.This particular molecule has a COOH group at one end that is acidic, and a methyl group at the other.roteins refer to groups of Amino Acids, which are a group of compounds that contain nitrogen (unlike carbohydrates and lipids), these molecules contian a carbonyl group (carbon double bonded with an oxygen) or a COO-group.
